Product Description	Recombinant Human B7-H4 Protein is expressed from HEK293 with His tag and Avi 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 28.2 kDa. Due to glycosylation, the protein migrates to 52-68 kDa based on Bis-Tris PAGE result.
Activity	Immobilized Human B7-H4, His Tag at 0.5 ug/ml (100 ul/Well) on the plate. Dose response curve for Anti-B7-H4 Antibody, hFc Tag with the EC50 of 3.1 ng/ml determined by ELISA. See testing image for detail.

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.
