分子别名(Synonym)

BTLA,CD272

表达区间及表达系统(Source)

Biotinylated Human BTLA (31-150), His,Avitag (BTA-H82E6) 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 polyhistidine tag at the C-terminus, followed by an Avi tag.

The protein has a calculated MW of 17.4 kDa. The protein migrates as 28-42 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Biotinylation)

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(Biotin:Protein Ratio)

The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Human HVEM, Mouse IgG2a Fc Tag, low endotoxin (Cat. No. HVM-H5255) at 5 μg/mL (100 μL/well) can bind Biotinylated Human BTLA (31-150), His,Avitag (Cat. No. BTA-H82E6) with a linear range of 0.156-2.5 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.
