| Usage |
Experimental equipment required for the experiment: 1. Microplate reader (450nm) 2. High-precision pipette and gun tips: 0.5-10uL, 5-50uL, 20-200uL, 200-1000uL 3. 37℃ constant temperature box 4. Distilled water or deionized water Sample processing and requirements: 1. Serum: Place the whole blood sample collected in the serum separation tube at room temperature for 2 hours or at 4℃ overnight, then centrifuge at 1000×g for 20 minutes, and take the supernatant, or store the supernatant at -20℃ or -80℃, but avoid repeated freezing and thawing. 2. Plasma: Collect specimens using EDTA or heparin as an anticoagulant and centrifuge at 1000 × g for 15 minutes at 2-8°C within 30 minutes of collection. The supernatant can be assayed immediately or stored at -20°C or -80°C, but avoid repeated freeze-thaw cycles. 3. Pre-Assay Preparation: 1. Remove the test kit from the refrigerator 10 minutes in advance and equilibrate to room temperature. 2. Prepare the standard gradient working solution: Add 1 mL of universal diluent to the lyophilized standard, let stand for 15 minutes to completely dissolve, then gently mix (concentration 10 ng/mL). Then dilute to the following concentrations: 10 ng/mL, 5 ng/mL, 2.5 ng/mL, 1.25 ng/mL, 0.625 ng/mL, 0.3125 ng/mL, 0.15625 ng/mL, and 0 ng/mL. Serial dilution method: Take seven EP tubes and add 500uL of universal diluent to each. Pipette 500uL of the 10ng/mL standard working solution into the first EP tube and mix thoroughly to make a 5ng/mL standard working solution. Repeat this procedure for subsequent tubes. The last tube serves as a blank well; there is no need to pipette liquid from the penultimate tube. See the figure below for details. 3. Preparation of biotinylated detection antibody working solution: Centrifuge the concentrated biotinylated antibody at 1000×g for 1 minute 15 minutes before use. Dilute the 100× concentrated biotinylated antibody to a 1× working concentration with universal diluent (e.g., 10uL concentrate + 990uL universal diluent). Prepare and use immediately. 4. Prepare the enzyme conjugate working solution: 15 minutes before use, centrifuge the 100× concentrated enzyme conjugate at 1000×g for 1 minute. Dilute the 100× concentrated HRP enzyme conjugate to a 1× working concentration with universal diluent (e.g., 10 μL of concentrate + 990 μL of universal diluent). Prepare immediately. 5. Prepare the 1× wash solution: Dispense 10 mL of 20× wash solution into 190 mL of distilled water (concentrated wash solution removed from the refrigerator may crystallize; this is normal. Allow to stand at room temperature until the crystals have completely dissolved before preparing). Procedure: 1. Remove the desired strips from the aluminum foil bag after equilibration at room temperature for 10 minutes. Seal the remaining strips in a ziplock bag and return to 4°C. 2. Sample addition: Add 100 μL of sample or standard of varying concentrations to the corresponding wells. Add 100 μL of universal diluent to the blank wells. Cover with a film and incubate at 37°C for 60 minutes. (Recommendation: Dilute the sample to be tested at least 1-fold with universal diluent before adding it to the ELISA plate. This will reduce the impact of matrix effects on the test results. The sample concentration should be multiplied by the corresponding dilution factor when calculating the final sample concentration. It is recommended to run replicates for all test samples and standards.) 3. Add Biotinylated Antibody: Remove the ELISA plate and discard the liquid without washing. Add 100 μL of Biotinylated Antibody Working Solution directly to each well. Cover with a film and incubate at 37°C for 60 minutes. 4. Wash: Discard the liquid and add 300 μL of 1x Wash Solution to each well. Let stand for 1 minute, shake off the wash solution, and pat dry on absorbent paper. Repeat this process three times (a plate washer can also be used). 5. Add Enzyme Conjugate Working Solution: Add 100 μL of Enzyme Conjugate Working Solution to each well. Cover with a film and incubate at 37°C for 30 minutes. 6. Washing: Discard the liquid and wash the plate five times as in step 4. 7. Adding substrate: Add 90 μL of substrate (TMB) to each well, cover with a sealing film, and incubate at 37°C in the dark for 15 minutes. 8. Adding stop solution: Remove the ELISA plate and add 50 μL of stop solution directly to each well. Immediately measure the OD value of each well at a wavelength of 450 nm. Calculating experimental results: 1. Calculate the average OD value of the standard and sample replicates and subtract the OD value of the blank well as a correction factor. Plot the standard curve of the four-parameter logistic function on double-logarithmic graph paper, with concentration as the horizontal axis and OD value as the vertical axis. 2. If the sample OD value is higher than the upper limit of the standard curve, dilute the sample appropriately and retest. Multiply the sample concentration by the corresponding dilution factor. |

| Theory | This kit uses a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Sample, standard, biotin-labeled detection antibody, and HRP enzyme conjugate are sequentially added to microwells pre-coated with Mini Samples for Platelet Derived Growth Factor BB capture antibody. After incubation and washing, the sample is developed using the substrate TMB. TMB is converted to blue by peroxidase (HRP) catalysis and to yellow by acid. The intensity of the color is positively correlated with the presence of Mini Samples for Platelet Derived Growth Factor BB in the sample. The absorbance (OD) is measured at 450 nm using a microplate reader to calculate the sample concentration. | |||||||||||||||||||||||||||||||||

|||||||||||||||||||||||||||||||||
| Background | Platelet-derived growth factor BB (PDGF-BB) is the most extensively studied isoform in skeletal cells. PDGF-BB, produced by activated platelets and macrophages, is the only factor to date demonstrated to selectively and directly promote phonotactic conversion. Thirty years ago, Blank and Owens, along with others (Li et al., 1997), demonstrated that treatment of VSMCs with PDGF-BB is associated with a rapid downregulation of multiple differentiation marker genes. | |||||||||||||||||||||||||||||||||
| General Notes | 1. Strictly adhere to the specified incubation time and temperature to ensure accurate results. All reagents must be at room temperature (20-25°C) before use. Refrigerate reagents immediately after use. 2. Improper plate washing may result in inaccurate results. Ensure that all liquid in the wells is aspirated thoroughly before adding substrate. Do not allow the wells to dry out during incubation. 3. Remove any residual liquid and fingerprints from the bottom of the plate, as this will affect the OD value. 4. The substrate developer solution should be colorless or very light in color. Do not use substrate solution that has turned blue. 5. Avoid cross-contamination of reagents and specimens to prevent erroneous results. 6. Avoid direct exposure to strong light during storage and incubation. 7. Do not expose any reagents to bleaching solvents or the strong fumes emitted by bleaching solvents. Any bleaching agent will destroy the biological activity of the reagents in the kit. 8. Do not use expired products, and do not mix components with different product numbers and batches. 9. Recombinant proteins from sources other than the kit may not be compatible with the antibodies in this kit and will not be recognized. 10. If there is a possibility of disease transmission, all samples should be managed properly and samples and testing devices should be handled according to prescribed procedures. |

Great batana oil for hair
Banana oil is so incredible, I will never stop singing its praises. I am prone to dry scalp and have thin, curly hair that needs just the right amount of moisture or it will frizz out. Batana oil has helped restore balance to my scalp and reduced flakes and it adds just enough moisture to my hair. This oil is a great version. It is thick, but not so thick that it doesn't melt in your hands if you rubs them together. I also have not noticed any stickiness or excessive left on my hands that can happen with some Banana oil brands. I do want to note that I usually put the batana oil on my scalp, let it sit for 15-20 minutes then wash it out, if you are going to let it stay in your hair, this may be too heavy for you. Otherwise, a great deal at the list price of $14, since a little goes a long way.

On the fence...
Will be updating review after I have used it for more than a week.
But so far here are the pros and cons:
Pros:
Smells good
Seems like a little goes a long way
Easy to apply
Cons:
Not sure if this is because I didn't use Sulfate free shampoo, but felt like with one wash I didn't get all the product out of my hair, so when It dried, it still looked greasy/oily
Will be washing my hair again with sulfate free shampoo, then will do another application in another day or so.
it says to use 2-3 times a week, so I'll use it 3 times a week for 2 weeks and then come back and update my review. But so far, it seams like a good product and for the money, it's a fair value.

Great For Dry Hair
I've never tried Batana Oil before, so I had no idea what to expect. It's a great oil for my hair. I love that it is all-natural oil and is more like a paste. It spreads easily on my hair. I love that I can put a tiny bit on my finger and rub it directly into my dry scalp.
The oil has an interesting but pleasant smell. It's hard to describe. It reminds me a bit of a cross between coffee and cacao, but more nutty and mild. I like it. It's not too strong.
The directions say to apply and leave in for 20 minutes, then wash out with a sulfate-free shampoo. I like to leave it in my hair for a day or two before washing it again. It's a great conditioning oil for dry and damaged hair. It might feel heavy on fine or thin hair, but I like it on my medium-thick hair.
The only reason I dropped this a star is that I'm dubious of the claim that it promotes hair growth. I think it helps my dry hair from breaking off, but I don't think it can do much for most hair loss. However, for hair conditioning, this is definitely a five star product.
