Isolation and PC12 cell proliferative protein fraction from pilose antler and its activity / 中草药

ABSTRACT

Objective The lyophilized pilose antler water extract(PAE) was isolated,and their cell proliferation on PC12 cells was observed.Methods S-200 Size-exclusive gel and DEAE negative ion-exchange liquid chromatograph were employed to fractionate the PAE.SDS-PAGE was employed to analyze the proteins composition of PAE.The protein concentration was determined by Folin-Phenol assay.The proliferation rates of PC12 cells were measured by MTT assay.Results The proliferation rate of PAE on PC12 cells at 13.3 mg/mL was 47%(P
