Add to each dilution tube 300uL Buffer for dilution ( 1× 4000pg/mL ), buffer for dilution ( 1× ) can be used as a standard curve zero ( 0pg/mL ）。 2. Operation steps 1. Prepare all necessary reagents and standards. 2. Take out the microplate from the sealed bag that has been equilibrated to room temperature. Please put the unused slats back into the aluminum foil bag and re-seal; 3. Add to the microplate 300uL Washing liquid, let stand and soak 30 Seconds, discard the lotion and pat the microplate dry on absorbent paper. Please use it immediately and do not let the microplate dry; 4. Add different concentration standards, experimental samples or quality control articles into the corresponding wells, and each well 100uL 。 Seal the reaction wells with plate sealing tape and incubate at room temperature 2 hour ; 5. Suck the liquid in the plate and wash the plate using a washing bottle, a multi-channel plate washer or an automatic plate washer. Washing solution per well 300uL Then the wash liquid in the plate is aspirated off. Repeat Operation 3 6. Within each well added 100uL 2 Hour; 7. Repeat th 5 Step washing operation; 8. Within each well added 100uLSA-HRP 20 Minutes. Be careful to avoid light; 9. Repeat th 5 Step washing operation; 10. Within each well added 100uL 5-30 Minutes, pay attention to avoiding light; 11. Within each well added 50uL Stop solution, the color of the solution in the well will change from blue to yellow. If the color of the solution changes to green or the color changes are inconsistent, pat the microplate gently to mix the solution evenly; 12. After addition of stop solution 30 Within minutes, measured using a plate reader 450nm Absorbance value, set 540nm Or 570nm As a correction wavelength. If dual-wavelength correction is not used, the accuracy of the results may be affected; 13. Calculation results: Add the corrected absorbance values of each standard and sample (OD450-OD540 OD570) , average of repeated well readings and then subtract the average zero standard OD Value. Using computer software for four-parameter logic (4-PL) Curve fitting creates a standard curve. Another way is to plot the standard concentration and make the logarithm with the corresponding OD The values were logarithmic to generate a curve, and the best fit line was determined by regression analysis. This process can generate a data fit that is sufficiently useful but less accurate. If the sample is diluted, the concentration should be calculated by multiplying the dilution factor. Note: The standard curve data provided is for reference only, and the sample content should be calculated according to the standard curve drawn in the same test. 3. Kit parameters 1. Recovery: Different levels were spiked into cell culture medium samples Rat IL-1β/IL-1F2 The recovery rate was determined. The recoveries range from 82-110% , the average recovery was in 94% 。 2. Sensitivity: Rat IL-1β/IL-1F2 The lowest measurable dose ( MDD ) is generally less than 1.8pg/mL 。 The lowest measurable value is determined according to 20 The corresponding concentration is calculated by adding two standard deviations to the mean value of the zero-point absorbance values of each standard curve. 3. Linearity: 4 High concentrations of different samples were incorporated into Rat IL-1β/IL-1F2 , followed by a diluent ( 1× ) Dilute the sample to the detection range and determine its linearity. 4. Specificity: This ELISA Method can detect natural and recombinant Rat IL-1β/IL-1F2 Egg whites. The following factors were mixed with diluent ( 1× ) configured to 50ng/mL Concentration to be detected with rats IL-1β Cross-reactivity of. Will 50ng/mL Interference factors incorporated into the intermediate range of recombinant rats IL-1β In the control article, to detect the effect on rats IL-1β Of interference. No significant cross-reactivity or interference was observed.

| Theory | This kit adopts double antibody sandwich enzyme-linked immunosorbent detection technology. Specific anti-rat IL-1beta/IL-1F2 antibodies were pre-coated on high affinity enzyme plates. The standard substance, the sample to be tested and the biotinylated detection antibody are added to the well of the enzyme label plate, and after incubation, the IL-1beta/IL-1F2 present in the sample binds to the solid phase antibody and the detection antibody to form an immune complex. After washing to remove unbound material, horseradish peroxidase-labeled Streptavidin-HRP was added. After washing, a chromogenic substrate is added to protect the color from light. A stop solution was added to stop the reaction, and the absorbance value was measured at a wavelength of 450 nm (reference calibration wavelength of 540 nm or 570 nm). | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

| Background | Interleukin -1 （ IL-1 ) Protein family members include classical IL-1 And IL-1 。 IL-1 Receptor antagonists ( IL-1RA ）、 IL-18 、 IL-33 、 IL-1F5-F10 、 IL-1 And IL-1 Have the same cell surface binding receptors and form the same biological function. Unstimulated cells in healthy people do not produce IL-1 The only exceptions are skin keratinocytes, some epithelial cells, and some cells of the central nervous system. But in response to inflammatory agents, infection, or microbial endotoxin, IL-1 Expression in macrophages and other types of cells increased dramatically. IL-1 In immune and inflammatory responses, bone remodeling, fever, carbohydrate metabolism, GH/IGF-1 Plays an important role in the physiological process of. Multiple diseases and IL-1 Dysregulated expression or delayed expression associated, including diseases related to sepsis, rheumatoid arthritis, inflammatory bowel disease, acute and chronic myeloid leukemia, insulin-dependent diabetes mellitus, atherosclerosis, nerve injury and senile degeneration. IL-1 And IL-1 Are structurally related polypeptides, at the amino acid level about 25% Homology of. Both are first synthesized into 31kDa Precursor, then cleaved to approximately 17.5kDa Of the mature protein. By Caspase-1/ICE Right IL-1 Cleavage of precursors is a critical step in the inflammatory response. Despite IL-1 And IL-1 Neither contain a typical hydrophobic signal peptide, but there is evidence that they can be secreted extracellularly through non-classical pathways. Unprocessed IL-1 Parts may be displayed on the cell membrane and may retain biological activity. With IL-1 The precursors are different, IL-1 Precursors vs. mature IL-1 Compared to having little or no biological activity. IL-1 Precursors vs. mature IL-1 All transported extracellularly. IL-1 And IL-1 Via immunoglobulin superfamily receptors and IL-1RA Combine to exert its effect. 80kDa Of I Type transmembrane receptor ( IL-1RI ) expressed in a variety of cells, including T Cells, fibroblasts, keratinocytes, endothelial cells, synovial lining cells, chondrocytes, and hepatocytes. 68kDa Of II Type transmembrane receptor ( IL-1RII ) in B Cells, neutrophils and bone marrow cells. IL-1RI And IL-1RII The extracellular region of 28% Homology of. But there are significant differences in other areas: II The intracellular domain of type receptor is only 29 Amino acids, and I The intracellular domain of type receptor is 213 Amino acids. IL-1RII It seems to be right IL-1 The signal does not respond, its function is to decoy the receptor and thus weaken IL-1 The role of. IL-1 Receptor ligand protein ( IL-1RAcP ) with IL-1RI The interaction is IL-1RI Necessary for signaling. IL-1RA Is a secreted molecule, is IL-1 Competitive inhibitors. Soluble IL-1RI And IL-1RII It is present in human plasma, joint fluid, and conditioned media of several cell lines. Moreover, vaccinia virus encodes similar to soluble IL-1RII Of IL-1 Binding proteins. |

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.
