Product Description	Recombinant Human B7-H7/HHLA2 Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Ile23-Asn344.
Product Background	B7-H7, also known as HHLA2 (HERV-H LTR-associating 2), is a member of the B7 family of immune regulatory proteins.Through interaction with TMIGD2, costimulates T-cells in the context of TCR-mediated activation. Enhances T-cell proliferation and cytokine production via an AKT-dependent signaling cascade.
Product Category	Recombinant Protein / Antibody discovery / Immune checkpoint proteins

Protein	B7-H7/HHLA2
Synonyms	B7H7; B7-H7; HHLA2; B7 Homolog 7
Accession	Q9UM44-1
Species	Human
Biotinylated	no
Amino Acid Range	Ile23-Asn344
Molecular Weight	The protein has a predicted MW of 63.7 kDa. Due to glycosylation, the protein migrates to 78-100 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human CD28H, His Tag at 5ug/ml (100ul/well) on the plate. Dose response curve for Human B7-H7, hFc Tag with the EC50 of 90.0ng/ml determined by ELISA (QC Test). The affinity constant of 334 nM as determined in SPR assay (Biacore T200). See testing image for detail.
