SPEED, SCALABILITY AND
PROVEN COMMERCIAL SUCCESS
Your Protein. A GMP-Ready
Manufacturing Process.
From sequence to scalable, manufacturing-ready process.
Whether you are evaluating a new molecule, improving
expression, scaling a process, or preparing for
manufacturing — we help you determine the right path
forward. Just tell us about your protein.
What Brings
Teams to Us
You don’t need to diagnose
the problem. Just tell us
what’s happening.
Sound familiar?
I need to express a new protein
Starting from sequence with no established production strategy.
..
My yields are too low or inconsistent
Expression works, but not at the level or quality required.
Site specific conjugation
I’m struggling to make a protein incorporating a ncAA coding sequence.
I’m running into downstream or quality issues
Purification challenges, impurities, or product quality constraints.
I need material for studies
Preclinical material, GLP lots, or data to support advancement decisions.
Platform
A high-yield microbial expression platform built on Pseudomonas fluorescens,
engineered specifically for biologics production, not adapted from a laboratory
research tool. Pfenex supports protein expression from early-stage evaluation
through manufacturing-ready process development. We integrate strain engineering,
process development, and analytics in one system — so you don’t have to manage
multiple handoffs.
Approved vaccines and therapeutics marketed worldwide by leading pharmaceutical companies.
