描述：

NTAL/LAB 抗体能检测内源性NTAL/LAB 蛋白总体水平。此多克隆抗体是通过合成人源性NTAL/LAB Gly222周围的肽段免疫动物而获得。抗体是通过protein A和多肽亲和层析法纯化。非T细胞活化连接(NTAL)/链接激活B细胞(LAB)是个小的跨膜转换蛋白与糖脂丰富的细胞膜片段相连(1,2)。 NTAL/LAB 也被称作 LAT2 (连接活化T 细胞 2), WBSCR5, WBS15, WBSCR15 (Williams-Beuren 综合症染色体区域15蛋白)。 NTAL/LAB在B 细胞, 单核细胞, 柱状细胞和自然杀伤细胞中表达, 但是在静息 T 细胞中不表达 (3)。除了激活一些受体外, NTAL/LAB 也能使酪氨酸磷酸化并招募信号分子Grb2 和 c-Cbl组成信号受体复合体(4-6)。

原厂资料：

Specificity / Sensitivity

NTAL/LAB Antibody detects endogenous levels of total NTAL/LAB protein.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly222 of human NTAL/LAB. Antibodies are purified by protein A and peptide affinity chromatography.

Background

Non-T cell activation linker (NTAL)/linker for activation of B cells (LAB) is a small transmembrane adaptor protein associated with glycolipid-enriched membrane fractions (1,2). NTAL/LAB is also known as LAT2 (linker for activation of T cells 2), WBSCR5, WBS15, WBSCR15 (Williams-Beuren syndrome chromosome region 15 protein). It is expressed in B cells, monocytes, mast cells, and natural killer cells, but not in resting T cells (3). Upon activation of several receptors, NTAL/LAB becomes tyrosine phosphorylated and recruits signaling molecules such as Grb2 and c-Cbl into receptor-signaling complexes (4-6).
