EastMabBio offers end-to-end custom development and manufacturing services for RUO-grade and GMP-grade recombinant proteins, supporting pre-clinical research, cell and gene therapy raw material preparation and clinical trial material manufacturing. Their custom protein service covers gene design, vector construction, protein expression, multi-step purification and comprehensive quality control testing. Leveraging both mammalian and E. coli expression platforms, production scales range from milligram-level research batches to gram-level manufacturing.
In addition, EastMabBio provides highly flexible protein engineering options for custom cytokines, including truncated variants, site directed mutants, fusion tag modification and special molecular modifications. RUO grade projects can be seamlessly upgraded to GMP grade material manufacturing by inheriting validated upstream and downstream processes, avoiding extensive process re-development. The custom products are widely applied in immune cell expansion, stem cell differentiation, organoid culture, cell function mechanism study as well as CGT related pre-clinical and clinical R&D. Every batch is supplied with complete documentation including COA, process records and sequence information.
Through Bio-Connect, customers in the Benelux can access EastMabBio’s RUO-grade and GMP-grade custom proteins solutions with local scientific and logistical support. Our team helps define your sequence, construct format, expression system, quality requirements (RUO or GMP oriented QC panel), and project scale expectations. We coordinate the whole custom development and manufacturing workflows with EastMabBio, and ensure reliable delivery of high-quality, fit-for-purpose cytokine reagents tailored to your research, assay development, organoid, immune cell and CGT projects.
