Ensuring a secure supply of Protein A resins for our customers

Why Join?

Supply shortages in the industry are resulting in longer lead times for Protein A resins. For early-phase antibody therapeutics, these can be as high as 8 months.

We know that keeping your process moving is vital now, more than ever, so we have have introduced the Protein A Resin Urgent Supply Scheme, a dedicated supply platform which guarantees delivery of Protein A resin to your site within weeks, not months. 

You will receive guaranteed, immediate access to off-the-shelf, pilot-scale volumes of best-in-class Protein A resins at dedicated, fixed prices. Whether you require bulk resin or pre-packed columns, our expedited lead times will ensure your processing goals are met efficiently and on-schedule.
