Name : Mouse B7-H4 Protein

Product Source :
Recombinant Mouse B7-H4 Protein is expressed from HEK293 with His tag at the C-terminus. It contains Leu25-Gly257.[Accession | Q7TSP5]

Molecular Weight :
The protein has a predicted MW of 26.70 kDa. Due to glycosylation, the protein migrates to 48-68 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 :
Lyophilized from 0.22 μm 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 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt.-80°C for 3-6 months after reconstitution.2-8°C for 2-7 days after reconstitution.Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Product Concentration :
Tris-Bis PAGE Mouse B7-H4 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Mouse B7-H4 is greater than 95% as determined by SEC-HPLC.

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 .

Synonyms :
B7H4; B7-H4; B7S1; B7h.5; B7x; FLJ22418; VTCN1; PRO1291
