Technologies available for transfer

Filgrastim (recombinant G-CSF) Technology​

Epygen Biotech employs recombinant DNA technology in E. coli to produce Filgrastim Biosimilar (recombinant G-CSF), optimizing a 175-amino-acid, non-glycosylated protein (18.8 kDa). An advanced high-density fermentation and precision refolding techniques, coupled with rigorous chromatographic purification ensures high-purity output. This scalable, cost-effective process targets chemotherapy-induced neutropenia and stem cell mobilization, meeting stringent quality standards. Technology is available for Bench, Pilot and CGMP scale transfer.

At Epygen Biotech, we offer technology for Filgrastim, a recombinant G-CSF, using *E. coli*-based systems at our facility near Mumbai, India. The process entails cloning the G-CSF gene into *E. coli* for enhanced protein expression. High-cell-density fermentation in bioreactors to optimize yield, followed by cell lysis to harvest Filgrastim-containing inclusion bodies (IB). These are denatured, refolded, and purified using advanced chromatography (e.g., ion-exchange, hydrophobic interaction) to achieve high purity. The protein is formulated with stabilizers and excipients and finally filled into vials or syringes under sterile cGMP conditions. Epygen’s innovative, cost-effective approach ensures affordable, high-quality Filgrastim producing technology for Oncology, meeting global regulatory standards.

Epygen Biotech employs advanced analytical and biological testing to ensure the quality and safety of its biopharmaceuticals, including recombinant proteins and biosimilars for oncology and cardiovascular diseases. Analytical tests, such as HPLC and mass spectrometry, verify purity, stability, and potency. Biological testing, including cell-based assays, confirms bioactivity and safety. Conducted in multiple facilities, these tests ensure compliance with global regulatory standards, supporting Epygen’s mission to deliver affordable, high-quality therapeutics.​
