The RA3-6B2 antibody reacts with the human and mouse CD45 isoform known as CD45R, or B220, a protein tyrosine phosphatase of 220 kDa. CD45 is one of the most abundant hematopoietic markers, and is expressed on all leukocytes (the Leukocyte Common Antigen, LCA). Various isoforms are generated and expressed in cell-specific patterns, all critical for leukocyte function. In mouse, the CD45R/B220 isoform is predominantly found on B cells, at varying levels on all stages from pro-B cells to activated B cells, and may also be detected on certain T cell and NK cell subsets. It is of note that B220 is not similarly expressed on human B cells, where it appears to be differentiation-specific and therefore expressed on only some B cell subsets. Other forms of CD45 with restricted cellular expression include CD45RA, CD45RB, CD45RO and several others.
The RA3-6B2 antibody is one of the most consistently used leukocyte markers for B cells, T cell subsets and NK cell subsets in human and mouse. This antibody has also been reported as cross-reactive with feline CD45R/B220.

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。
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。
