Biological CRO Services --->Services Overview

Services Overview  

 ACRObiosystems is one of the leading research provider for bulk proteins and antibody products. We offer exceptional speed without compromising product quality.

Our Integrated Solutions eliminate uncertainty shorten the production timeline

  • We can go from gene sequences to the milligram level, and then all the way to the gram level expression of proteins within 4-5 weeks.
  • Our unique cell clone screening/assay strategies are able to produce stable cell lines in just two months.
  • Our well characterized processes ensure product consistency and reliability.

High throughput production of proteins and monoclonal antibodies from the milligram all the way to the gram level

  • Parallel production of hundreds of known proteins/mAb at 10mg/L - 1g/L titers with 40 1 - 2L cell culture vessel.
  • Downstream Purification and Analysis services based on our expertise dealing with hundreds of different proteins.

Our Process Platform

  • Highly effective expression system with highly pure reagents, including vectors, host cell lines, and chemically well-defined media.
  • Well established cell culture and compatible downstream purification systems
