Validation Data Gallery

• 

  Purity of Recombinant Human CD48 was determined by SDS-PAGE. The protein was resolved in an SDS-PAGE in reducing (R) conditions and stained using Coomassie blue.

• 

  Immobilized Human CD48 (Myc tag, His tag) at 2 μg/mL (100 μL/well) can bind Biotinylated Human CD244 (hFc tag, Myc tag, His tag) with a linear range of 66-264 ng/mL.

Background

Signaling lymphocytic activation molecule family 2 (SLAMF2, CD48) is an adhesion and costimulatory molecule expressed constitutively on most hematopoietic cells, particularly in antigen presenting cells (APC). CD48 is expressed on all the hematopoietic cells, both in human and mice, except for murine neutrophils and long term-HSC. as a number of GpI receptors do, also CD48 exists as both a membrane bound (mCD48) and a soluble (sCD48) form. CD48 can have activating roles on T cells, antigen presenting cells and granulocytes, by binding to CD2 or bacterial FimH, and through cell intrinsic effects. Interactions between CD48 and its high affinity ligand CD244 are more complex, with both stimulatory and inhibitory outcomes. CD48 expression is increased in autoimmunity and allergy diseases, and anti-CD48 monoclonal antibodies have been shown to attenuate experimental autoimmune encephalomyelitis.
