WALTHAM, Mass., June 28, 2018 (GLOBE NEWSWIRE) -- Repligen Corporation (NASDAQ:RGEN), a life sciences company focused on bioprocessing technology leadership, today announced it has entered into an agreement with Purolite Life Sciences to supply its next-generation Protein A ligand, NGL-Impact™ A,  which will be commercialized by Purolite Life Sciences using their novel Praesto® agarose jetting base bead technology. Repligen is a longtime market leader in Protein A, with two facilities that produce the majority of the global Protein A ligand demand to biopharmaceutical customers worldwide.

NGL-Impact™ A was developed as part of Repligen’s collaboration with Navigo Proteins GmbH. This new ligand has outstanding performance attributes when immobilized on jetted agarose bead technology, with ultra-high binding capacities and excellent alkaline stability. These attributes are important in providing improved monoclonal antibody capture to handle increased upstream product titres, and in allowing higher concentrations of sodium hydroxide (NaOH) for sanitization of resins.

Purolite Life Sciences’s jetting technology is a new patented method that produces agarose beads with a uniform particle size distribution to drive higher capacity and increase pressure flow properties.  

Tony J. Hunt, Repligen CEO, said, “We are delighted by this agreement with Purolite Life Sciences, which is a natural extension of our existing Protein A supply agreement with them. We look forward to seeing how this next-generation ligand performs in the marketplace with Purolite Life Sciences’s Praesto® jetted agarose bead technology.”

Chris Major, VP of Sales for Purolite Life Sciences said, “We are pleased that Repligen has chosen Purolite Life Sciences to commercialize their next generation ligand. We’ve been very impressed in evaluations by the ligand’s overall performance characteristics, particularly the high binding capacity and caustic stability features that are so important to an efficient biologics manufacturing process. We look forward to continuing a productive relationship with Repligen and adding this ligand technology into our suite of products.”

The Protein A ligands and growth factor products that we produce are essential components of Protein A affinity resins and cell culture media, respectively. Protein A affinity resins are the industry standard for downstream separation and purification of monoclonal antibody-based therapeutics. Our growth factors are used in upstream processes to accelerate cell growth and productivity in a bioreactor. Our innovative line of OPUS® chromatography columns, used in downstream processes for bench-scale through clinical-scale purification needs, are delivered pre-packed to our customers with their choice of resin. Our XCell™ ATF Systems, available in stainless steel and single-use configurations, are used upstream to continuously eliminate waste from a bioreactor, to concentrate cells and increase product yield. Single-use Sius™ TFF cassettes and hardware are used for biologic drug concentration in downstream filtration processes. Spectrum KrosFlo™ TFF cartridges and systems are used in both upstream and downstream filtration processes. Repligen’s corporate headquarters are in Waltham, MA (USA), with additional administrative and manufacturing operations in Shrewsbury, MA, Rancho Dominguez, CA, Lund, Sweden and Ravensburg, Germany.
