Unconjugated Human TPBG / 5T4 Protein, His,Avitag™
分子别名（Synonym）
TPBG,5T4,M6P1,5T4AG,WAIF1,5T4 oncofetal antigen,Trophoblast glycoprotein,5T4 oncofetal trophoblast glycoprotein
表达区间及表达系统（Source）
Unconjugated Human TPBG, His,Avitag (TPG-H52E5) is expressed from human 293 cells (HEK293). It contains AA Ser 32 - Ser 355 (Accession # Q13641-1).
Predicted N-terminus: Ser 32
蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 39.0 kDa. The protein migrates as 50-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
应用说明（Application）
TPG-H52E5 is the unconjugated version of TPG-H82Eb (Biotinylated Human TPBG, His,Avitag). It can be utilized for assay development or customized biotinylation according to the experimental designs.
内毒素（Endotoxin）
Less than 0.1 EU per μg by the LAL method / rFC method.
纯度（Purity）
>90% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
滋养层细胞糖蛋白（TPBG），亦称5T4，是多个临床研发阶段抗癌药物的治疗靶点，这主要归因于其在肿瘤组织中高表达、在正常成人组织中低表达的特性。该基因编码一种富含亮氨酸的跨膜糖蛋白，可能参与细胞粘附过程。TPBG在胚胎发育早期（最早9周）即表达于所有类型的滋养层细胞中。
