Alternative Names:
CD276; B7H34Ig-B7-H3; B7-H3; B7 homolog 3; CD276 antigen; CD276 molecule; Costimulatory molecule
Apparent Molecular Weight:
65-90 KDa, reducing conditions
Background:
CD276, also known as B7-H3, is a member of the B7 superfamily with signature IgV and IgG regions in extracellular domains. It is a type I transmembrane protein and shares 20?27% amino acid identity with other B7 family members. B7-H3 is involved in the activation of T lymphocytes, and regulates murine bone formation. It is also reported that B7-H3 may play an important role in muscle-immune interactions, providing further evidence of the active role of muscle cells in local immunoregulatory processes. B7-H3 is expressed on T-cells, natural killer cells, and antigen presenting cells, as well as some non-immune cells, such as osteoblasts, fibroblasts, fibroblast-like synoviocytes and epithelial cells. High expression of B7-H3 in tumor vasculature also correlates with poor survival in patients, suggesting that it may play a role in tumor cell migration.
Biological Activity:
Immobilized Human B7-H3-His(Cat#CK62) at 2ug/ml (100 ul/well) can bind Anti-Human B7-H3 mAb(Cat#NC055 ) The ED50 of Anti-Human B7-H3 mAb(Cat#NC055 ) is 7.98 ng/ml.
Endotoxin:
Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.
Molecular Weight:
47.3 KDa
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 100ug/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.?
