描述

SLAMF2/CD48 protein is a GPI-anchored glycoprotein that regulates immune cell function by interacting with CD2 and CD244. SLAMF2/CD48 Protein, Human (HEK293, mFc) is the recombinant human-derived SLAMF2/CD48 protein, expressed by HEK293 , with C-mFc labeled tag. The total length of SLAMF2/CD48 Protein, Human (HEK293, mFc) is 194 a.a., with molecular weight of 60-80 kDa.

研究背景

SLAMF2/CD48 蛋白是一种糖基磷脂酰肌醇 (GPI) 锚定的细胞表面糖蛋白,通过其 N 端免疫球蛋白结构域与细胞表面受体(如 2B4/CD244 或 CD2)相互作用,在免疫细胞调节和激活中发挥关键作用。在T细胞信号转导中,SLAMF2与CD2结合,促进Src家族蛋白激酶LCK和LAT有效招募至TCR/CD3复合物,从而促进LCK磷酸化和随后的激活。此外,SLAMF2 诱导 CD244 的细胞质免疫受体酪氨酸开关基序 (ITSM) 磷酸化,启动一系列信号传导事件,最终形成免疫突触,并通过 T 淋巴细胞和颗粒酶直接释放含有穿孔素和颗粒酶的溶细胞颗粒。NK 细胞。值得注意的是,SLAMF2 直接与 CD2、CD244 和 LCK 相互作用,突显其在免疫细胞功能和信号通路中的复杂参与。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2
