精密度
批内差:已知浓度的3个样本在一个板子内重复检测20次,以评估批内精密度。
批内 CV: ≤4.5%
批间差:已知浓度的3个样本在不同的板子上重复测定5次,以评估测定批间精密度。
批间 CV: ≤8.9%
回收率
回收率:低、中和高浓度的分析物被掺入到血清或者血浆样本中,进行回收实验测定。

通用注释


亚单元:
Predominantly monomer of isoform CD22-beta. Also found as heterodimer of isoform CD22-beta and a shorter isoform. Interacts with PTPN6/SHP-1, LYN, SYK, PIK3R1/PIK3R2 and PLCG1 upon phosphorylation. Interacts with GRB2, INPP5D and SHC1 upon phosphorylation (By similarity). May form a complex with INPP5D/SHIP, GRB2 and SHC1.


功能:
Mediates B-cell B-cell interactions. May be involved in the localization of B-cells in lymphoid tissues. Binds sialylated glycoproteins; one of which is CD45. Preferentially binds to alpha-2,6-linked sialic acid. The sialic acid recognition site can be masked by cis interactions with sialic acids on the same cell surface. Upon ligand induced tyrosine phosphorylation in the immune response seems to be involved in regulation of B-cell antigen receptor signaling. Plays a role in positive regulation through interaction with Src family tyrosine kinases and may also act as an inhibitory receptor by recruiting cytoplasmic phosphatases via their SH2 domains that block signal transduction through dephosphorylation of signaling molecules.


亚细胞位置:
Cell membrane Single-pass type I membrane protein
