Comparison of four methods for the purification and refolding of human interleukin-2-mouse granulocyte/macrophage colony-stimulating factor fusion protein.

abstract：:Recently, hPNAS-4 [human PNAS-4; also known as C1orf121 (Genbank accession number NP-057160)] was reported to be a novel pro-apoptotic protein in mammalian cells. However, at present there is little information about hPNAS-4 and its molecular mechanisms. In our present studies, the hPNAS-4 gene was first cloned into t...
