Human CD21 is a receptor for complement fragments C3d, C3dg or ic3D (1, 5) and also EBV (4). CD21 is also a ligand for CD23 and plays a role in IgE synthesis (3).
Isotype: Murine IgG1
Immunogen: Human HFB-1 cell line
Specificity: Antibody BU33 recognizes the CD21 molecule of about 145 kd (1). BU33 has been shown to bind to Equine B cells, suggesting cross reactivity (7).
Functional Application: Antibody BU33 inhibits the CD21 - CD23 interaction (2, 6, 8).

【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
