Recombinant Proteins

​Biopharma PEG provides a portfolio of high-purity recombinant proteins engineered to meet the rigorous standards of biopharmaceutical research and development. Produced in E. coli or yeast expression systems and refined through robust purification workflows, our proteins deliver reliable performance with high purity, consistent biological activity, and low endotoxin levels.

Leveraging our expertise in PEG chemistry, selected proteins can also be supplied in PEGylated formats using aldehyde, NHS, maleimide, or site-specific conjugation strategies to enhance stability, solubility, and pharmacokinetics.

Every batch undergoes comprehensive analytical characterization, including SEC-HPLC, RP-HPLC, SDS-PAGE, MALDI-TOF, endotoxin testing, and peptide mapping, ensuring the quality and reproducibility required for advanced research, formulation development, and early-stage drug discovery.

We offer recombinant protein services and PEGylation services, delivering high-quality PEG solutions to support efficient and reliable protein modification. Contact us at sales@biochempeg.com for more details.
