ABSTRACT
Active fractions were obtained from the c(?)amworm homogenate by reverse-phase concentration, gel filtration and affinity column chromatography. The MTS/PMS assay was used in the screening of antimicrobial peptide in vitro. The MTS/PMS assay and ELISAAFP method were combined to evaluate the effects of antimicrobial peptide on the proliferation and ?-fetoprotein secretion of HepG2 cells as well as on the proliferation of normal mouse osteoblast MC3T3-E1. The results showed that the purified antimicrobial peptide from clamworm Murphysa sanguinea was a constitutive basic protein with MW 8.1 kDa and pI 8.6, which showed inhibition effects on the proliferation and ?-fetoprotein secretion of HepG2 cells at different levels. These effects have a positive correlation with the concentrations of antimicrobial peptide. No obvious inhibition and damage effects were observed on the normal osteoblast.
