Active Recombinant Human VTCN1, MIgG2a Fc-tagged

• Cat.No.: VTCN1-531H
• Product Overview: The extracellular domain of human B7-H4(NP_078902.2)(Phe29-Ala258) is fused to the N-terminus of the Fc region of mouse IgG2a.

Specification

• Species: Human
• Source: CHO
• Tag: Fc
• Protein Length: 29-258 a.a.
• Description: This gene encodes a protein belonging to the B7 costimulatory protein family. Proteins in this family are present on the surface of antigen-presenting cells and interact with ligand bound to receptors on the surface of T cells. Studies have shown that high levels of the encoded protein has been correlated with tumor progression. A pseudogene of this gene is located on chromosome 20. Multiple transcript variants encoding different isoforms have been found for this gene
• Form: Lyophilized from 0.2μm-filtered solution in PBS.
• Bio-activity: Measured by the ablility to inhibit anti-CD3-induced proliferation of stimulated human T cells. Human T lymphocytes cultured for 72 hours with PHA were incubated for an additional 3 days in 96 well place coated with 500 ng/ml antiCD3 and 10 ug/ml human B7
• Molecular Mass: 55 KDa (monomer)
• AA Sequence: Phe29-Ala258
• Endotoxin: <0.06 eu/μg="" as="" determined="" by="" lal="" test.="">
• Purity: >98%, by SDS-PAGE under reducing conditions.
• Stability: Stable for at least 1 year after receipt when stored at -20°C. Working aliquots are stable for up to 3 months when stored at -20°C.
• Reconstitution: Reconstitute at 100μg/ml in sterile PBS.
• Warning: Avoid freeze/thaw cycles.
