Bio-Rad says its technical bulletin 5574A proves Bio-Rad's Bio-Scale Mini Profinity cartridges offer comparable or better yield and purity to other commercially available prepacked affinity columns
The study was performed using Bio-Rad's Profinia protein purification system.
Affinity-tagged purification of recombinant proteins is a common procedure performed in laboratories using glutathione-S-transferase (GST) and polyhistidine (His) affinity tags.
The Profinia protein purification system simplifies the process by automating the purification and desalting of these tagged proteins in a single step.
Bio-Scale Mini Profinity chromatography cartridges are prepacked, disposable, and designed for use on chromatography instruments.
The cartridges offer a number of advantages such as ease of use and reproducibility.
The Profinia system is a chromatography instrument that contains preprogrammed optimized methods for affinity purification of tagged proteins and antibodies resulting in increased efficiency and reproducibility in the laboratory.
It takes as little as 30 minutes to purify the protein of interest and dramatically reduces time and effort.
