Description
Biotinylated Human B7-H7 / HHLA2 Protein, His, Avitag™ (MALS verified) | B77-H82E3-200ug| Gentaur Distribution US, UK & Europe
B7-H7 (HHLA2) is a newly identified B7 family member that regulates human T-cell functions. B7-H7 was previously known as human endogenous retrovirus-H long terminal repeat associating 2 (HHLA2) with unidentified function. Recently, B7-H7 has been identified as a specific ligand for human CD28H. The B7-H7-CD28H pathway strongly promoted CD4+ T-cell proliferation and cytokine production via an AKT-dependent signaling cascade in the presence of TCR signaling, suggesting B7-H7 comprises a new co-stimulatory pathway. The first IgV domain of B7-H7, which presumably binds to a putative receptor, shows the highest homology to other B7 family members.
Source: Biotinylated Human B7-H7, His, Avitag (B77-H82E3) is expressed from human 293 cells (HEK293). It contains AA Ile 23 - Asn 344 (Accession # Q9UM44-1).
Format: Powder.
Tag: C-10×His & C-Avi.
Expression System: HEK293.
Expression Region: Ile 23 - Asn 344.
Conjugate: Biotin-labeled.
Molecular Weight: 40.7 kDa.
Characteristics: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 40.7 kDa. The protein migrates as 50-66 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
