Product Description	Recombinant Human B7-H4 Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Phe29-Ala258.
Product Background	B7-H4, also known as B7x and B7S1, is a 50-80 kDa glycosylated member of the B7 family of immunomodulatory proteins.B7-H4 is up-regulated in several carcinomas in correlation with tumor progression and metastasis. A soluble form of B7-H4 is elevated in the serum of ovarian cancer, renal cell carcinoma, and rheumatoid arthritis patients, also in correlation with advanced disease status-.
Product Category	Recombinant Protein / Antibody discovery / Immune checkpoint proteins

Protein	B7-H4
Synonyms	B7H4; B7-H4; B7S1; B7h.5; B7x; FLJ22418; VTCN1; PRO1291
Accession	Q7Z7D3-1
Species	Human
Biotinylated	no
Amino Acid Range	Phe29-Ala258
Molecular Weight	The protein has a predicted MW of 52.1 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human B7-H4, hFc Tag at 0.5ug/ml (100ul/Well) on the plate. Dose response curve for Biotinylated Anti-B7-H4 Antibody, hFc Tag with the EC50 of 7.8ng/ml determined by ELISA. See testing image for detail.
Product Tag	C-hFc
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um 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.
