BTLA, CD272

表达区间及表达系统（Source）

Biotinylated Human BTLA (31-150) (M105V, G138S, V148M), Fc,Avitag (BTA-H82F5) is expressed from human 293 cells (HEK293). It contains AA Lys 31 - Ser 150 (Accession # AAP44003.1 (M105V,G138S,V148M)).

Predicted N-terminus: Lys 31

蛋白结构（Molecular Characterization）

This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 41.9 kDa. The protein migrates as 53-60 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记（Labeling）

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度（Protein Ratio）

Passed as determined by the HABA assay / binding ELISA.

纯度（Purity）

>95% as determined by SDS-PAGE.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 25 mM Arginine, 150 mM NaCl, pH7.5 with trehalose as protectant.
