Correction: Bioproduction, characterization, anticancer and antioxidant activities of extracellular melanin pigment produced by newly isolated microbial cell factories Streptomyces glaucescens NEAE-H

scientificreports inhibitory effects of melanin pigment on cell growth using standard 3-(4, 5 dimethythiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay 63 .should read:Both safety and the anticancer activities of the purified melanin pigment of Streptomyces glaucescens strain NEAE-H were measured in vitro on both cancerous (skin cancer cell line (A-431)) and non-cancerous cells (human lung fibroblast (WI-38) and human amnion (WISH)) which obtained from ATCC via holding company for biological products and vaccines (VACSERA), Cairo, Egypt.A-431 cell line was used to determine the inhibitory effects of melanin pigment on cell growth using standard 3-(4, 5 dimethythiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay 63 .
