Recombinant Protein Expression And Purification

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.
