Product Description	Recombinant Human B7-H7/HHLA2 Protein is expressed from HEK293 with His 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 38.1 kDa. Due to glycosylation, the protein migrates to 50-70 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human B7-H7, His Tag at 5 ug/ml (100 ul/well) on the plate. Dose response curve for Human CD28H, hFc Tag with the EC50 of 63.4 ng/ml determined by ELISA (QC Test). See testing image for detail.
Product Tag	C-His
Expression System	HEK293
Purity	>95% as determined by Bis-Tris PAGE;>95% as determined by HPLC
Endotoxin	Less than 1 EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution	Centrifuge the tube before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
