Description
Biotinylated Mouse CD28 Protein, His, Avitag™, active dimer (MALS verified) | CD8-M82E3-25ug| Gentaur Distribution US, UK & Europe
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.
Source: Biotinylated Mouse CD28, His, Avitag (CD8-M82E3) is expressed from human 293 cells (HEK293). It contains AA Asn 20 - Lys 149 (Accession # P31041-1).
Format: Powder.
Tag: C-10×His & C-Avi.
Expression System: HEK293.
Expression Region: Asn 20 - Lys 149.
Conjugate: Biotin-labeled.
Molecular Weight: 18.6 kDa.
Characteristics: This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 18.6 kDa. The protein migrates as 34-42 kDa under reducing (R) condition, and 60-70 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.
