表達區(qū)間及表達系統(tǒng)(Source)
Mouse Siglec-2, His Tag (SI2-M52Ha) is expressed from human 293 cells (HEK293). It contains AA Ser 22 - Arg 702 (Accession # P35329-1).
Predicted N-terminus: Ser 22
蛋白結構(Molecular Characterization)
![1.jpg 1.jpg](/SupplyImg1/2025-02-10/6387478189692272638213061.jpg)
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 78.3 kDa. The protein migrates as 100 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>95% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

背景(Background)
B細胞受體CD22也被稱為唾液酸結合Ig樣凝集素2(Siglec-2)、B淋巴細胞粘附分子(BL-CAM)、T細胞表面抗原Leu-14,屬于免疫球蛋白超家族和Siglec(唾液酸結合Ig-like凝集素)家族。CD22介導B細胞與B細胞的相互作用,并可能參與B細胞在淋巴組織中的定位。Siglec-2/CD22結合唾液酸化糖蛋白,其中之一是CD45。Siglec2/CD22通過與Src家族酪氨酸激酶的相互作用在正向調(diào)節(jié)中發(fā)揮作用,也可能通過其SH2結構域招募細胞質(zhì)磷酸酶來充當抑制性受體,SH2結構區(qū)通過信號分子的去磷酸化阻斷信號轉(zhuǎn)導。
