背景介绍
CD22, also known as Siglec-2 (sialic acid binding Ig-like lectin 2) or BL-CAM (B-lymphocyte cell adhesion molecule), is a 130-140 kDa, B-cell restricted, type I transmembrane glycoprotein belonging to the immunoglobulin gene superfamily. The expression of CD22 is developmentally regulated. It is expressed at low levels in the cytoplasm of pro-B and pre-B cells and present on the cell surface only at mature stages of B-cell differentiation. Cell surface expression is lost during terminal differentiation into plasma cell and after B-cell activation. CD22 is an inhibitory receptor for B-cell receptor (BCR) signalling, preferentially binds to alpha-2,6-linked sialic acid and mediates B-cell B-cell interactions. It plays a crucial role in activation and differentiation of the B-cell.

CD22 分子 CD22 常用单克隆抗体或代号： B3,HD39,Leu14,SHCL- 1,HC2 (BL- CAM) 主要表达细胞： B [B] 分子质量(kDa)和结构： gp130/140,髓鞘(磷)脂相关蛋白类似物(MAG)(IgSF) 功 能： 与CD45RO、CD75结合,B细胞粘附到M、红细胞,介导B- B、B- T细胞相互作用 CD22 Aka B
抗体的检测外，还应该用与其抗原成分相关的其它抗原进行交叉试验，方法可用ELISA、IFA法。例如：①制备抗黑色素瘤细胞的McAb，除用黑色素瘤细胞反应外，还应该用其它脏器的肿瘤细胞和正常细胞进行交叉反应，以便挑选肿瘤特异性或肿瘤相关抗原的单克隆抗体。②制备抗重组的细胞因子的单克隆抗体，应首先考虑是否与表达菌株的蛋白有交叉反应，其次是与其它细胞因子间有无交叉。 2．McAb的Ig类与亚类的鉴定 一般在用酶标或荧光素标记的第二抗体进行筛选时已经基本上确定了抗体的Ig类型
-CAM-L1、MAG、Po、F3、NILE、TAG1等以及CD22、CD48、α1-BgP分子等。某此IgH链中C H 2和C H 3可有8个β折叠，在这种情况下，其中一个β折叠股只有3个氨基酸残基。 在V、C1和C2三组中，有些Ig超家族成员之间的同源性要大于该组中平均的类似程度，如在V组中IgV、TCR-V、和CD8V结构域；C1组中IgC、TCR-C、MHC-C结构域；C2组中CD2和LFA-3，NCAM、NCAM-L1和MAG
