CD28-UNLB, CD28.2, 0.2 mg, ASR
Product No:IM1376
The CD28 antigen (Tp44) is a homodimer of disulfide-linked chains, with a molecular weight of 44 kDa each. CD28 antigen is expressed by a majority of CD3+ T lymphocytes. CD4+ T lymphocytes express the CD28 antigen more frequently than do CD8+ T lymphocytes. CD28 antigen is also present on plasma cells and thymocytes. This antigen is involved in the adhesion of T lymphocytes with B lymphocytes, through the B7/BB-1 (CD80) or B70/B7-2 (CD86) glycoproteins and provides a major co-stimulatory signal for T cell activation.
