Human CD272 (BTLA, B and T Lymphocyte Attenuator) is a member of the Immunoglobulin superfamily and has sequence homology to PD-1 and CTLA4. It is expressed on T and B lymphocytes and other hemopoetic lineages. Engagement of this molecule by its ligand, CD270(HVEM, a TNF superfamily member) can down regulate activated T and B cell responses. CD272 levels on antigen specific CD8+ T cells have been reported to decrease in viral specific, but not melanoma specific activated lines (1). Polymorphism of the CD272 molecule has been linked to rheumatoid arthritis (3).
Antibodies ANC6E9(cat #272-020) and ANC5A5(cat #372-020) each bind to a distinct epitope of CD272 and are suitable as a matched pair for EIA (see attachment).
Isotype: Murine IgG1k
Immunogen: Recombinant extracellular human CD272
Specificity: Antibody from clone ANC5A5 binds to CD272 on the cell surface of human PBMC in Flow cytometry, and to recombinant CD272-muIg (cat #542-020) in EIA.
Functional Application: Antibody ANC5A5 does not block binding of Biotinylated CD270(HVEM)-muIg(cat #531-030) to CD272-muIg in EIA, but appears to enhance this interaction.

【消过毒的无菌棉球】分几种
1、放在铁盒子里一起消过毒的
2、放在超净台上、用紫外照过30min的
急求，谢谢了！
个人大胆一次，把内表面用酒精灯考一下，让表面重新融化。就可以了。各位可以用一块有机版的边缘试试。
测流式由侧面通过工作台（左右 上下皆可），于是缺点就是在气流层边缘可能出现负压，导致污染。而且其较为封闭，只有手伸入的圆洞，取拿物品较为
2、关闭紫外灯，打开风机；
3、消毒液消毒台面、手
4、无菌操作
5、整理台面，关闭风机
