Recombinant Human CD28 protein, His-Avi-tagged, Biotinylated

• Cat.No.: CD28-747HB
• Product Overview: Biotinylated Recombinant human CD28 Protein is expressed from mammalian with a His Tag and Avi Tag at the N-terminal. It contains Thr17-Pro152.

Specification

• Description: 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.
