Process

How It Works

01

Proposal preparation

We work closely with you to define the optimal manufacturing strategy, scope, timeline and quality requirements for your plasmid DNA project.

02

Cell Banking

Generation and characterization of Master and Working Cell Banks (MCB/WCB) to ensure a reliable, traceable and reproducible starting material for manufacturing.

03

Fermentation

Scalable microbial fermentation under tightly controlled conditions to maximize plasmid DNA yield, quality and batch-to-batch consistency.

04

Cell Harvesting and Lysis

Efficient recovery of biomass followed by optimized cell lysis to release plasmid DNA while preserving its integrity and maximizing recovery.

05

Two-step chromatography

High-performance chromatographic purification designed to remove impurities and deliver highly pure plasmid DNA suitable for your intended application.

06

Fill & Finish

Aseptic formulation and filling into the final container, including liquid or lyophilized presentations, under GMP-compliant conditions for clinical or commercial supply.
