Anti-breast cancer synthetic peptides derived from the Anabas testudineus skin mucus fractions
Abstract Previous study has shown the antimicrobial activities of mucus protein extracted from Anabas testudineus. In this study, we are interested in characterizing the anticancer activity of the A. testudineus antimicrobial peptides (AMPs). The mucus was extracted, fractioned, and subjected to ant...
