    背景
    CD28 is the receptor for CD80 (B7-1) and CD86 (B7-2) proteins.When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen presenting cells (APCs). The CD86 expression on antigen presenting cells is constitutive. CD28 is the only B7 receptor constitutively expressed on naive T cells.
    分子量
    18.2 kDa. Due to glycosylation, the protein migrates to 36-52 kDa based on Tris-Bis PAGE result.
