Biotinylated Human B7-H4 Protein (BH7-HM174B) Summary
Product Description |
Recombinant Biotinylated 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. |

Shipping, Reconstitution, & Storage
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 |
Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
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. |
