Description

Introduction
B- and T-lymphocyte attenuator, also known as B- and T-lymphocyte-associated protein, BTLA and CD272, is a Single-pass type I membrane protein which Contains 1 Ig-like V-type (immunoglobulin-like) domain. BTLA expression is induced during activation of T cells, and BTLA remains expressed on Th1 cells but not Th2 cells. Like PD1 and CTLA4, BTLA interacts with a B7 homolog, B7H4. However, unlike PD-1 and CTLA-4, BTLA displays T-Cell inhibition via interaction with tumor necrosis family receptors (TNF-R), not just the B7 family of cell surface receptors. BTLA is a lymphocyte inhibitory receptor which inhibits lymphocytes during immune response. BTLA also is a ligand for tumour necrosis factor (receptor) superfamily, member 14 (TNFRSF14), also known as herpes virus entry mediator (HVEM). BTLA-HVEM complexes negatively regulate T-cell immune responses.

BP001608-C563: Recombinant Human B- and T-lymphocyte attenuator (BTLA) Protein

Source: HEK 293-derived.
Recombinant Human B- and T-lymphocyte attenuator (BTLA) Protein is expressed with sequence (Lys31-Leu150) of Human BTLA (Uniprot #Q7Z6A9) fused with a polyhistidine tag at the C-terminus.
Purity: > 95% by SEC-HPLC and reducing SDS-PAGE.
Endotoxin: < 0.1 ng/ug (1 IEU/ug).
Formulation: lyophilized from a 0.2 um filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.
Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 ug/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Shipping: The product is shipped with ice pack. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70°C as supplied.
