Prokaryotic Expression and Identification of Actin Protein in Laticifer Cells of Rubber Tree(Hevea brasiliensis Müll.Arg.)
摘要
Abstract
ACTIN,a component of cytoskeleton,is one of the constituents of the plugs at the end of the severed laticifers.In order to study the interaction of ACTIN with proteins in the plugs,the A CTIN gene prokaryotic expression vector was successfully constructed.Recombinant protein was expressed in abundance in the E.coil BL21 (DE3) after being induced by 0.1 mmol/L IPTG for 2 hours at 37 ℃.The recombinant protein with a molecular mass of about 41.7 ku was mainly present as inclusion body.It was further purified by Ni-NTA affinity chromatography and identified by western-blot with mouse anti-HIS tagged monoclonal antibody.This study laid a good foundation of revealing the mechanism for plug formation at the end of severed laticifers.关键词
