重组CC家族趋化因子RANTES的原核表达及趋化活性分析
Expression in E.coli and Chemotactic Activity Analyzing of Recombinant CC-chemokine RANTES
摘要
Abstract
Objective To further understand the structure and function of RANTES and provide basis for research
for application. Methods PCR product corresponding to region encoding mature RANTES protein was
cloned into E.coli expression vector;, purified recombinant protein was obtained by heparin affinity chro
matography and its chemotactic activity was determined by Boyden chamber. Results The recombinant
RANTES was expressed in E.coli with high efficiency. Purified protein showed chemotactic activity to pe
ripheral blood lymphocytes, U937 cells, and CCR4 stable-transfected HEK293 cells. Conclusion The puri
fled recombinant protein exerted chemotactic activity on PBL and cultured cell lines, and we have estab
lished a experimental system for further study of structure and function of RANTES.关键词
