Abstract
We report the cloning, purification and cell proliferative activity of a novel recombinant GST tagged human granulocyte macrophage colony stimulating factor (GST-hGMCSF). The hGMCSF gene was PCR amplified from the cDNA of ACHN renal carcinoma cells and was cloned into the bacterial expression vector. The GST-hGMCSF was purified to homogeneity using glutathione agarose affinity chromatography and subsequently characterized by Western blot, circular dichroism (CD) and MALDI TOF-TOF analysis. Homology modelling studies revealed the possible binding domains of the recombinant cytokine with cognate receptor. The proliferation of THP-1, Raw 264.7, MCF-7 and U87MG cells upon GST-hGMCSF addition was found to be dose dependent. Hence, this functionally active recombinant cytokine has potential application in cancer therapy for stimulating facile growth recovery of normal cell population.
