Recombinant protein expression and purifification
Technical service advantages
More than 10 years of experience inrecombinant protein research
High success rate of expression
Convenient separation operation
5L-500L large-scale expression capacity
One-stop protein customization
High purity, high bio-activity
Characteristics of eukaryotic expression cells
It has the function of post-translational modi-fication and folding, which can make theexpressedprotein closer to natural molecularstructure, physicochemical properties andbiological functions.
Characteristics of prokaryotic expression cells
It has a clear genetic background, low cost, highexpression amount, and relatively simple separa-tion and purification process.
