IMG-EK (pro-EMAPII), also known as p43, is a new cytokine that stimulates apoptosis in endothelial cells. IMG-EK (pro-EMAPII) is one of the three auxiliary components invariably associated with nine aminoacyl-tRNA synthetases as a multienzyme complex . IMG-EK (pro-EMAPII), recombinant , is a 34.3kDa polypeptide containing 312 amino acids, that induces cell death of endothelial cells in vitro (1) and demonstrates potent anti-angiogenic activity (2,3).

IMG-EK (pro-EMAPII), recombinant, is supplied as a dried powder.

Optimal Biological Range
For most in vitro applications IMG-EK (pro-EMAPII) exerts its biological activity in the concentration range 1nM~1uM.

Dried IMG-EK (pro-EMAPII) is soluble in water and most aqueous buffers and can be diluted into other buffered solutions and stored at -20°C for future use.

Recombinant DNA expressed in E. coli.

Storage Temperature
Store dried IMG-EK (pro-EMAPII), desiccated at -20°C. Avoid exposure to frequent temperature changes. Store reconstituted IMG-EK (pro-EMAPII), in aliquots at -20°C. The performance of this product is guaranteed for at least six months from the date of purchase, if stored and handled properly.

Biological Activity
The ED50 for FGF, Basic, i.e., the concentration of factor that produces one-half the maximal response, is determined in a cytotoxicity bioassay using bovine aortal endothelial cells in DMEM with 10% FBS and MTT assay. The ED50 value obtained is reported on the Product Information Label affixed to this document.
