It is a member of the immunoglobulin superfamily and is also known as T44 or Tp44. CD28 is expressed on most T lineage cells, NK cell subsets, and plasma cells. CD28 binds both CD80 and CD86 using a highly conserved motif MYPPY in the CDR3-like loop. CD28 is considered a major co-stimulatory molecule, inducing T lymphocyte activation and IL-2 synthesis, and preventing cell death. In vitro studies indicate that ligation of CD28 on T cells by CD80 and CD86 on antigen presenting cells provides a costimulatory signal required for T cell activation and proliferation.\u003c\/p\u003e\n\n\u003cp\u003eConcentration: 0.5 mg\/mL\u003c\/p\u003e\n\n\u003cp\u003eControl Catalogue Number: E-AB-F097930\u003c\/p\u003e\n\n\u003cp\u003eBuffer: 0.2 μm filtered in PBS, pH 7.2.
