Catalog no. :  RKP01590

Optimized DNA sequence  encoding extracellular domain of mouse CD25  including a C-terminal polyHis tag was expressed in HEK293 cells.

Molecular weight:

Recombinant mouse CD25 is a monomer protein consisting of 223 amino acid residue subunits,  due to glycosylation migrates as an approximately 50 kDa protein on SDS-PAGE.

>97%, as determined by SDS-PAGE and HPLC

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

Recombinant CD25  is supplied as a 0.2 μm filtered PBS solution,  pH7.2 .

Recombinant CD25, as supplied, can be stored in working aliquots at 2° - 8° C for one month, or at -20°C to -70°C for twelve months.

Avoid repeated freeze/thaw cycles.

This cell surface antigen is known also as TAC antigen . It is expressed on T-cells and B-cells following cell activation by antigens. An old designation for the murine counterpart is Ly43 . The rat antigen is OX39. CD25 is identical with IL2RA , which is the approved gene symbol. It is called also T- cell growth factor receptor (TCGFR)
