  • Background: T-cell-specific surface glycoprotein CD28 is also known as TP44, is a single-pass type I membrane protein which contains one Ig-like V-type (immunoglobulin-like) domain. is one of the molecules expressed on T cells that provide co-stimulatory signals, which are required for T cell activation. CD28 is the receptor for CD80 (B7.1) and CD86 (B7.2). 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.
  • Exp Region: Asn 19 - Pro 152
  • Swiss-prot: P10747
  • Characteristics: This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 43.6 kDa. The protein migrates as 55-70 kDa under reducing (R) condition, and 110-130 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
