Abstract
This study was aimed to investigate the effect of a singlechain fragment variable antibody of connective tissue growth factor antiCTGF scFv against the differentiation of fibroblast into myofibroblast The scFv antibody was firstly expressed in Escherichia coli cells and was then purified by affinity chromatography The yield scFv protein reached a purity over 95 after purification Immunoreactivity assay demonstrated that scFv possessed a special affinity toward CTGF RTPCR western blot and immunofluorescence experiments showed that increased expression of αsmooth muscle actin induced by TGFβ1 could be suppressed by this scFv antibody through inhibiting the phosphorylation of AktWe thanked the Natural Science Foundation of Jiangsu Province China no BK2009274 the Science Foundation of Southeast University no 3290000102 and the National Science Foundation of China grant numbers 30970809 and 30840042 for the financial support to this work Meanwhile we thanked Dr Xiaobo Fan and Dr Jing Xiong for the careful revision to this paper
