Product Specification
| Usage | Before the trial guidelines: 1, the corresponding animal experiment, EdU suggested initial dosage of 50 mg/kg (50 mu g/g), dilute concentration is 0.5 1 mg/mL. Are injected into mice weight 20 g, mg, 1 to 1 mg/mL, need injection of 1 mL. 2, for the cells, the recommended 10 microns, EdU work for in vitro culture cell, specific EdU use concentration, incubation time along with the samples and research purpose is different, can be adjusted appropriately. 3. This kit can be used for EdU experiments of about 200T in 6-well plates, and EdU experiments of about 2000T in 96-well plates or paraffin sections. The amount of use should be calculated according to the sample conditions during the experiment. I. Sample processing 1. Animal experiments (1) EdU injection in animals For mice, EdU can be prepared with PBS at a dose of 10 to 200mg/kg and injected intraperitoneally, locally into specific tissues or organs, or added to drinking water. The specific dosage is related to the type, weight and mode of use of animals, and can be referred to the relevant literature. Therefore, it is recommended to conduct a certain exploration of the use concentration of EdU for the first use, or directly use the concentration of 50mg/kg for testing. Injection methods: according to customer experiments, such as intraperitoneal injection, subcutaneous injection, intramuscular injection, tail vein injection, etc., among which intraperitoneal injection is the most common. After 6 hours or according to the specific experiments to determine the appropriate time, quickly kill mice, take out the organization, in accordance with the general steps to make frozen section and paraffin section. EdU tag when also can consult relevant literature to adjust. Small intestinal epithelial cells proliferate rapidly, and positive information can be detected 6 hours after EdU injection in adult mice, which can be used as a positive control for pre-experiments. (2) slice processing Before slicing processing: best cleaning tissues and organs, to remove residues in the tissues of the blood, EdU, reduce the background. It is advisable to slice thickness: 3-10 microns, biopsy had thick could affect the background and dyeing efficiency. Slice post-processing: Paraffin dewaxing: dimethyl benzene dewaxing 2 times, 15 minutes per times, gradient ethanol (100%, 95%, 85%, 75%), 5 minutes per times, deionized water elution 1 times. Processing of frozen sections: After 30 min at room temperature, the sections were fixed for 10 min and washed three times with PBS for 5 min each. 2, cell experiment (1) EdU labeling of cells a.with cell complete medium and EdU mother liquor by 2000:1 the ratio of dilution, preparation of a moderate amount of 100 microns EdU medium; b.each hole adding suitable amount of 10 microns EdU medium 2 hours incubation, abandon culture medium (optimal incubation time for 1/10 of the cell cycle) commonly, EdU incubation medium and EdU reaction liquid volume may refer to the table below; c.Cells were washed 3 times with PBS for 5 minutes each time
(2) cells fixed fully a.Cell fixative (PBS containing 4% paraformaldehyde) was added to each well and incubated at room temperature for 15 minutes. The fixative was discarded and washed with PBS for 3 times, 5 minutes each time. b.Each well was decolorized with an osmotic agent (0.5% TritonX-100 in PBS) and incubated for 15 minutes. PBS was washed three times for 5 min each. Second, EdU response

| Description | EdU(5-ethynyl-2' -deoxyuridine), also known as 5-ethynyl-2' -deoxyuridine (5-ethynyl-2' -deoxyuridine), is a thymidine analogue with an alkynyl hydroxyl group that is rare in natural compounds and can replace thymidine (thymidine, 5-ethynyl-2' -deoxyuridine) in cell proliferation. thymidine (thymidine) is inserted into the replicating DNA molecule, the ethynyl group on EdU can react covalently with the fluorescently labeled small molecule Azide probe (Azide Alexa Fluor 488, etc.) through the catalysis of copper monovalent ion to form a stable triazole ring. "It is called the Clickreaction, which allows for an efficient and rapid measurement of cell proliferation, especially the percentage of cells in S phase." Compared with the traditional immunofluorescence staining (BrdU) detection method, EdU is only 1/500 of the size of BrdU antibody, and it is easier to diffuse in cells. It does not require strict sample denaturation (acid hydrolysis, pyolysis, and enzymatic hydrolysis), which effectively avoids sample damage and helps to observe the real situation of cell proliferation at the overall level of tissues and organs. Has higher sensitivity and faster detection speed.
According to PB, CU: AC: 488 chromogen = 855: spoken, Catalan than column configuration EdU reaction liquid (liquid of reaction is used). Each sample add 50-500 mu L EdU staining reaction liquid liquid evenly cover samples (reaction), 15 to 60 minutes at room temperature away from light incubation, abandon the dyeing liquid reaction, PBS wash 3 times, each time for 5 minutes. 3. DAPI staining DAPI(100x) was diluted with PBS at a ratio of 1:100 to make ready-to-use DAPI staining solution. 50-500μL of DAPI staining solution was added to each sample and stained in the dark for 15 minutes, followed by three washes with PBS for 5 minutes each. 4. Take pictures Fluorescence microscope, confocal microscope or whole-film scanner were used to collect images. After staining, the slides were stored in a dark place at 4℃. Above are stained images of 50mg/kg labeled mice for 6 hours. |

Treasure!! The best!!
I had been using Avene Compensating cream for years before it was reformulated and renamed as “Revitalizing” in (as I remember) 2020. At the time, every single comment I saw complained about its pilling and its getting worse after reformulation. Every single comment wished for the old formulation back. Because Avene Compensating was PERFECT for me, I got very anxious after reading the comments and decided not to purchase the new Revitalizing cream. I jumped around from products to products for the last 2 years (from expensive La Mer cream, Cle de peau La Creme, Lancome soft cream, Amorepacific Time Response to less expensive Clarins Hydra, Embryolisse). Nothing beat Avene Compensating cream. Nothing came close to Avene Compensating cream in terms of giving my easily irritated skin that clear, well moisturized, trouble-free, healthful look. Fast forward to the week of Thanksgiving 2022 after I got back from a Las Vegas trip with terribly dry and dehydrated reddish skin that nothing helped (and I always use sheet masks daily), I decided to give Avene Revitalizing a try. Worst case scenario, I would waste my $40 that I, very likely, would otherwise waste on another non Avene moisturizer. I’m so grateful I gave it a try. I don’t know if Avene listened to its loyal customers and brought the old formulation back, or if they improved the new formulation that pilled, but the Avene Revitalizing cream (I tried both rich and regular versions) did not pill at all for me and as far as I can still remember, Avene Compensating cream felt the same to me. After 2 nights of Avene Revitalizing, my skin is pretty much back to normal now. I think this is the old formulation but I can’t say for sure because it was more than 2 years ago when I last used the cream, but no matter what, if it keeps being what it is now, I will be a customer for life. Please Avene. Don’t change formulation again.
