Human BTLA (31-150) Protein, Fc Tag

分子别名(Synonym)

BTLA,CD272

表达区间及表达系统(Source)

Human BTLA, Fc Tag (BTA-H5256) is expressed from human 293 cells (HEK293). It contains AA Lys 31 - Ser 150 (Accession # AAP44003.1).

Predicted N-terminus: Lys 31

蛋白结构(Molecular Characterization)

Online(Lys 31 - Ser 150) AAP44003.1

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 40.4 kDa. The protein migrates as 46-66 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>92% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human HVEM, His Tag (Cat. No. HVM-H52E9) at 5 μg/mL (100 μL/well) can bind Human BTLA, Fc Tag (Cat. No. BTA-H5256) with a linear range of 0.02-0.625 μg/mL (QC tested).

Protocol

背景(Background)

B- and T-lymphocyte attenuator (BTLA) is also known as B- and T-lymphocyte-associated protein, CD antigen CD272. BTLA contains one Ig-like V-type (immunoglobulin-like) domain. As a lymphocyte inhibitory receptor, BTLA / CD272 inhibits lymphocytes during immune response. BTLA / CD272 can interact with tyrosine phosphatases PTPN6/SHP-1 and PTPN11/SHP-2, and interact with TNFRSF14/HVEM.
