POROS® Analytical Chromatography Columns

High Performance Resin for Analytical and Lab-Scale Separations

POROS Analytical Columns, with 10 and 20 micron particle size resins, deliver excellent resolution at high speed for both analytical and lab-scale preparative applications.

POROS Protein A Analytical Columns are the industry standard for monitoring monoclonal antibody titer and yield from cell culture supernatant.


Affinity Resin

  • POROS® A 20 µm Columns, PEEK™
    Prepacked Protein A Affinity Column is based on an immobilized recombinant Protein A functional group designed for high throughput purification of antibodies.
  • POROS® G 20 µm Columns, PEEK™
    Prepacked Protein G Affinity Column is based on an immobilized recombinant Protein G functional group designed for high throughput purification of antibodies.

Activated Affinity Resin

  • POROS® AL 20 µm Columns, PEEK™
    Prepacked Immobilized Aldehyde Affinity Column is based on an aldehyde functional group designed for the immobilization of proteins through free amine groups.
  • POROS® EP 20 µm Columns, PEEK™
    Prepacked Immobilized Epoxide Affinity Column is based on an epoxide functional group designed for the immobilization of proteins through free amine groups.
  • POROS® OH 20 µm Columns, PEEK™
    Prepacked Immobilized Hydroxyl Affinity Column is based on an hydroxylated functional group designed for the immobilization of proteins through activation with tresyl-chloride, divinyl-sulphone or cyanogen bromide.
