Prokaryotic proteins purification services

prokaryotic expression is the method of inserting cloned gene into suitable vector and introducing into E. coli for expression of large amounts of protein.prokaryotic expression system is by far the mature and reliable protein expression system which rapidly express and purify a variety of protein sources. Prepared recombinant protein can be used for drug screening, structural biology, cell biology, proteomics and other fields of biomedical.Based on different expression requirements, such as volume of expression, viability of targeted protein and different purification method, we choose proper expression system and corresponding expression strategy. We make use of our mature and steady protein purification system to optimize expression terms and purify targeted protein.
