Purexa™ PrA
for Antibody Purification

Our Protein A based affinity membrane chromatography product for capture-step antibody purification. Purexa™ PrA utilizes a convection-based mechanism to improve efficiency, purity, and yield.>

 

Purexa™ PrA DBC 10% versus Speed

  • Loading Buffer: 1xPBS pH 7.3 (15 mS/mL)

  • Sample: 2 mg/mL polyclonal human antibody in Loading Buffer

  • Residence time: 0.6 - 4.8 seconds

 

Increase Productivity with Purexa

Compared to magnetic and resin beads, Purexa™ PrA affinity membrane chromatography is unaffected by pore diffusion and has no incubation time with overall shorter processing times. Purexa™ PrA can operate at rapid flow rates to enhance productivity while maintaining high purity eluates.

 

Purilogics’ membranes can purify
and are not limited to these common biologics :

The Purexa™ product line has pore sizes ranging from 0.3µm to 5 µm. With a much larger pore size, the target molecule is easily able to bind to the membrane at a high capacity, regardless of the size. Thus, Purilogics’ membrane chromatography products can be applied for the purification of many sizes of biologics while also maintaining and a rapid flow rate and high binding capacity.
