Biologic activities of recombinant human-beta-defensin-4 toward cultured human cancer cells
Aim - the aim of the study was in vitro analysis of biological activity of recombinant human beta-defensin-4 (rec-hBD-4). Methods: hBD-4 cDNA was cloned into pGEX-2T vector, and recombinant plasmid was transformed into E. coli BL21(DE3) cells. To purify soluble fusion GST-hBD-4 protein, affinity chr...
