MonoSpin ProG

Brand: MonoSpin

MonoSpin ProG is a protein G functionalized spin column for the purification of antibodies. Protein G is a bacteria-derived protein that binds to the Fab and Fc regions of immunoglobulins. The monolithic silica skeleton is specially modified with a hydrophilic polymer then immobilized with Protein G providing rapid purification and high recovery of antibodies.

Overview

Purification of IgG Using MonoSpin ProA and MonoSpin ProG in only 5 min.

Sample can be neutralized and maintained in stable condition by putting neutral solution in tube when recovering anti-body.

As shown below, the anti-body concentrations were determined quantitatively from medium of CHO cells. The purified antibodies show very less impurities by the results from electrophoresis.

High recovery of Antibodies

Both MonoSpin ProA and MonoSpin ProG have 90% recovery (max 0.4 mg MonoSpin Pro A, max 0.3 mg MonoSpin ProG). MonoSpin ProG enables higher recovery and purification of IgG3 over MonoSpin ProA.

Higher efficiency sorbent

The monolithic silica phase used in MonoSpin columns is state-of-the-art in stationary phase technology allowing high recovery and adsorption and desorption performance. The structure of the silica allows for less obstruction of the binding proteins compared to conventional particle based phases allowing for much higher efficiency of separation.
