Abstract:
Objective:To study the function of transcription factor 4 (TCF4) and to prepare TCF4 polyclonal antibody.Methods:pET-41/TCF4 was transformed into E.coli BL21(DE3) and induced by IPTG.The purified GST-TCF4 fusion protein was applied to immunize rabbit to produce antiserum. The specificity of the affinity of purified anti-TCF4 antibody was examined by Western blotting analysis of the eukaryotic expressed products of TCF4. Dig-labeled probe and antibody against TCF4 were used to examine the expression of TCF4 in Saos-2 cells under mechanical stretch. Results:Western blotting showed that the antibody could bind to TCF4 specifically. The expression of TCF4 mRNA and protein were significantly increased in Saos-2 cells under mechanical stretch. Conclusion: TCF4 antibody has been prepared successfully.
