Name : Biotinylated Human B7-H7/HHLA2 Protein
Product Source :
Recombinant Biotinylated Human B7-H7/HHLA2 Protein is expressed from HEK293 with His tag and Avi tag at the C-terminus. It contains Ile23-Asn344.[Accession | Q9UM44-1]
Molecular Weight :
The protein has a predicted MW of 39.88 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Supplied as 0.22 μm filtered solution in PBS (pH 7.4).
Reconstitution :
Storage and Stability :
Valid for 12 months from date of receipt when stored at -80°C. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Biotinylated Human B7-H7 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Biotinylated Human B7-H7 is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Biotinylated Human B7-H7, His Tag at 1μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Human CD28H, hFc Tag with the EC50 of 4.9ng/ml determined by ELISA.
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.
Synonyms :
B7H7; B7-H7; HHLA2; B7 Homolog 7
