描述：

TRA-1-81抗体识别内源性的TRA-1-81抗原蛋白。此单克隆抗体由人类胚胎癌细胞2102Ep cl.2A6免疫动物产生。TRA-1-60和TRA-1-81抗体识别存在于人干细胞、胚胎癌细胞、胚胎生殖干细胞表面的抗原蛋白（1）。TRA-1-60(S)与神经氨酸酶敏感型抗原表位的蛋白聚糖相互作用（2,3），而TRA-1-81与神经氨酸酶非敏感型的相同抗原表位相互作用。近来，这种抗原蛋白被认为是足糖萼蛋白的一种形式（4）。而在生殖细胞肿瘤病人的血清中也检测到TRA-1-60的存在（5,6）。

原厂资料：

Specificity / Sensitivity

TRA-1-81 antibody detects endogenous levels of TRA-1-81 antigen.

Source / Purification

Monoclonal antibody is produced by immunizing animals with human embryonal carcinoma 2102Ep cl.2A6 cells.

Background

TRA-1-60 and TRA-1-81 antibodies detect antigens present on the surface of human stem, teratocarcinoma, and embryonic germ cells (1). TRA-1-60(S) reacts with a neuraminidase sensitive epitope of a proteoglycan (2,3), while TRA-1-81 reacts with a neuraminidase insensitive epitope on the same antigen. Recently this antigen has been proposed to be a form of the protein podocalyxin (4). TRA-1-60 is also detected in the serum of patients with germ cell tumors (5,6).
