Source:
Optimized DNA sequence  encoding extracellular domain of human CD48 including a C-terminal 6His tag was expressed in HEK293 cells.

 
Molecular weight:

Recombinant human CD48 is a monomer protein consisting of 205 amino acid residue subunits,  due to glycosylation migrates as an approximately 40 kDa protein on SDS-PAGE.


 
Purity:
>95%, as determined by SDS-PAGE and HPLC

 
Biological Activity
The activity was tested by immobilized recombinant CD48 (10ug/ml) ability to bind recombinant CD244 with a linear range of 20-100 ng/ml.

 
Endotoxin:
Endotoxin content was assayed using a LAL gel clot method.
Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

CD48

CD48 is a glycosylphosphatidylinositol -anchored protein belonging to the CD2 subfamily. It is expressed mainly on hematopoietic cells and exists in both membrane- associated and soluble forms . It is a low-affinity ligand for CD2 and is implicated as an important costimulatory molecule in lymphocyte activation. Indeed, CD48 has been described as facilitating cell adhesion, innate responses to bacterial infection, and graft rejection. In addition, CD48 is a high- affinity ligand for 2B4. CD482B4 interactions can modulate T cell, B cell, and natural killer (NK) cell functions and cross-talk.The absence of functional 2B4 CD48 interactions impairs NK cell cytotoxic response and IFN- release on tumor target exposure. Furthermore, activated NK cells significantly increase the CD3-dependent proliferation of CD8+ and CD4+ T cells by a 2B4CD48-dependent mechanism.
