BP005585: Biotinylated Human/Cynomolgus/Rhesus macaque CD28 Protein with the N-His-Avi Tag (生物素化的人/食蟹猴/恒河猴 CD28 蛋白 N-His-Avi 标签)
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.
