Background: B7 Homolog 4 (B7-H4) is glycosylated member of the B7 family of immune costimulatory proteins.It is widely expressed, including in kidney, liver, lung, pancreas, placenta, prostate, spleen, testis and thymus. B7-H4 negatively regulates T-cell-mediated immune response by inhibiting T-cell activation, proliferation, cytokine production and development of cytotoxicity. When expressed on the cell surface of tumor macrophages, plays an important role, together with regulatory T-cells (Treg) , in the suppression of tumor-associated antigen-specific T-cell immunity. It also involved in promoting epithelial cell transformation.

Description: Recombinant Rhesus Macaque V-set Domain-containing T-cell Activation Inhibitor 1 is produced by our Mammalian expression system and the target gene encoding Phe29-Ala258 is expressed with a Fc tag at the C-terminus.

Alternate Names: B7S1, B7x, Vtcn1, B7h.5, B7-H4, B7H4T-cell costimulatory molecule B7x, B7S1VCTN1, B7XPRO1291, FLJ22418, Immune costimulatory protein B7-H4, Protein B7S1, T cell costimulatory molecule B7x, V-set domain containing T cell activation inhibitor 1, V-set domain-containing T-cell activation inhibitor 1

Purity: Greater than 95% as determined by reducing SDS-PAGE.

Redissolve: Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles. 

Endotoxin: Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.

Molecular Weight: 52.5 KDa

Observed Molecular Weight: 70-100 KDa, reducing conditions

Storage: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
