Why choose Praesto® Jetted A50?

Praesto® Jetted A50 demonstrates superior Protein A purification performance characteristics, including:

  • Ultra-high dynamic binding capacity of ~ 80 g/l
  • Increased productivity and process economics
  • Alkaline stabilized Protein A
  • Increased surface area from patented 'Jetting' manufacturing method
  • Ideal for continuous chromatography and intensified batch processing

How have we achieved this?

​​​​​​Praesto Jetted A50 is a novel, agarose-based Protein A affinity resin with industry-leading performance characteristics, and utilizes a new ligand from Repligen Corporation - NGL-ImpactTM A.

It is the first Protein A resin to meet the future demands in mAb processing, and the only bioprocess-scale agarose resin available with a uniform particle size distribution. 

This is achieved by using a patented 'Jetting' manufacturing technology - an innovative process that produces agarose beads with a uniformity coefficient of <1.3. This delivers superior performance characteristics when compared to other resins.
