Anti-phosphotyrosine antibody is a tyrosine phosphorylation specific antibody that is part of the Signal-Seeker™ product line. APY03 anti-phosphotyrosine mouse monoclonal antibody clone 27B10 has been tested in western blot, immunofluorescence, immunoprecipitation and ELISA with excellent specificity and low background with strong potent signals. APY03 phosphotyrosine antibody recognizes a wide range of tyrosine phosphorylated proteins in cells treated with kinase inhibitors, hydrogen peroxide (H2O2) and sodium vanadate (Figure 1).
APY03 is a mouse monoclonal antibody 27B10 that recognizes phosphorytated tyrosine residues. APY03 was raised against a proprietary mixture of phosphotyrosine peptides conjugated to KLH. APY03 can detect 10 ng of phosphotyrosine-labeled bovine serum albumin (see Certificate of Analysis [COA]). APY03 is purified by protein G affinity chromatography and is supplied as a lyophilized white powder. Each Lot of antibody is quality controlled to provide a high batch to batch consistency. The Lot specific µg per tube can be found in the Lot specific COA documents at www.cytoskeleton.com. APY03 shows high specificity to phosphotyrosine peptides and does not cross-react with phosphoserine/threonine peptides in a western blot or an ELISA assay (Figures 1 & 4).
Figure 1: Western Blot using Phosphotyrosine Antibody
APY03 is highly specific for p-Tyr and does not recognize p-Ser or p-Thr tagged proteins. To see the full Western blot protocol, see the product datasheet.
Figure 2: Immunoprecipitation using Phosphotyrosine Antibody
APY03 was able to enrich a wide range of tyrosine-phosphorylated proteins from NIH3T3 cells treated with H2O2-activated orthovanadate. No signal was detected with Protein G bead control without APY03. To see the full Immunoprecipitation protocol, see the product datasheet.
Human epidermoid carcinoma A431 cells, untreated (3A) or treated (3B) with EGF (100 ng/ml for 3 minutes), and NIH3T3, untreated (3C) or treated (3D) with H2O2-activated sodium orthovanadate (100 µM for 10 minutes), were stained as described in the method. Phosphotyrosine and nuclei were visualized in green fluorescence and blue DAPI staining, respectively. To see the full Immunofluorescence protocol, see the product datasheet.
Figure 4: ELISA using Phosphotyrosine Antibody
Data show that APY03 does not crossreact with phosphothreonine and phoophoserine modified BSA. To see the full ELISA protocol, see the product datasheet.

We examine the broad effects of this cascade by looking at the phosphorylation patterns of proteins, specifically tyrosine-phosphorylated proteins. In the past we used the anti-phosphotyrosine antibody, 4G10, from Millipore, a staple for these type of westerns. When presented with an opportunity to try a different antibody, APY03, from your company, we were eager to see the results. Overall, we were pleased with the consistent result when compared with the Millipore antibody. In addition, the most significant advantage between the two antibodies was the huge savings in pricing. With these two factors, reduction in cost and reliable results, we will continue to use your product and suggest it to others." Jeff McDermott and Gladis SanchezUniversity of Kansas Medical Center Customer Results Reviewed Product: Anti-Phosphotyrosine Mouse Monoclonal Antibody (Cat. # APY03) Application:Western blot “I have compared APY03 and 4G10 antibodies and I believe that APY03 is as good as 4G10 with the advantage of APY03 being that it is cheaper and also you get more western blots out of one purchase compared to 4G10.” Felipe Navarrete, University of Massachusetts Customer Results Western blot analysis of extracts from non-capacitated (N. Cap) and capacitated sperm (Cap). Cap extracts express a high level of proteins that are phosphorylated on tyrosine residues. Manufacturers’ protocols followed. Primary antibody dilution of APY03 was increased to 1:5000 and still produces a robust signal that detects phosphotyrosine residues undetected by 4G10.

想买消炎药怎么办?
去药店买药想买不是抗生素的消炎药，那工作人员说不是抗生素怎么消炎呢，请问知情网友求一替代品，谢了。
以下来自摆渡百科
细胞在发生凋亡时，会激活一些DNA内切酶，这些内切酶会切断核小体间的基因组DNA。细胞凋亡时抽提DNA进行电泳检测，可以发现180-200bp的DNA ladder。基因组DNA断裂时，暴露的3’-OH可以在末端脱氧核苷酸转移酶(Terminal
Deoxynucleotidyl Transferase, TdT) 的催化下加上荧光素 (FITC) 标记的dUTP
(fluorescein-dUTP) ，从而可以通过荧光显微镜或流式细胞仪进行检测，这就是TUNEL (TdT-mediated dUTP
Nick-End Labeling) 法检测细胞凋亡的原理。
sc-153是兔抗大鼠ERK2的多克隆抗体
还有很多关于ERK1和ERK2的抗体

我们会按照你的实验需求推荐最适合你的产品。
你看这个抗体的质量怎么样，说明里面有没有说可以做组化，还是只能做western blot。
第二个问题：兔子不能免疫兔子的。免疫的一个重要概念是识别“自己”和“非己”，如果对自己的蛋白产生免疫反应，那就麻烦了。
可以类比器官移植，亲缘关系越近，越不容易产生免疫排斥。
