pAVEway™ Microbial Expression Platform
pAVEway™ is an efficient microbial protein expression and scale-up platform
pAVEway™ is a proven and innovative technology platform for the efficient microbial expression of proteins based on E.coli. The system offers industry-leading titers with proven scalability in more than one hundred projects over the last decade. Time to first clinical manufacture and strain generation has been reduced from six to four weeks, through ambr™ 250 technology.
Antibiotic-free fermentation ensures low regulatory risk without the loss of yield or versatility. And the class leading fermentation productivity ensures high yield recombinant protein production for a wide range of targets.
pAVEway™ offers efficient expression for a wide range of biotherapeutic proteins, through a variety of accumulation routes; intracellular soluble, intracellular insoluble, and periplasmic secretion. The optimal route can be tailored for each individual protein.

Platform description
Host cells
Available host cells include a panel of E.coli host cells. The cell lines were selected for their ability to express recombinant proteins with great efficiency and because of their robust fermentation performance at high cell densities.
Fast track process definition
Rapid entry into first clinical manufacture is accomplished by the integrated use ambr™250 technologies to achieve strain generation in four weeks.
Unique protein vectors and expression controls
pAVEway™ expression is based on unique protein vectors that are designed to maintain transcription control via DNA looping. Modulation of expression is based on level of inducer added. The technology allows for the manipulation of induction conditions to optimize accumulation allowing for maximization of protein expression as either inclusion bodies, cytoplasmic soluble or periplasmic secretion.
Batch feed and induction protocols
pAVEway™ is based on batch medium with a pre-developed feed strategy that delivers high ‘protein productive’ biomass levels – with proven scalability. Induction protocols are pre-developed, no matter how the protein is expressed:
- Inclusion body formation
- Soluble intracellular accumulation
- Secretion – periplasmic/growth medium

Rapid and scalable upstream process development with ambr® 250
High-throughput design and analysis tools ensure rapid, scalable upstream process development. Workflow is accelerated by automated screening for specificity and productivity using integrated ambr™ 250 technology. By implementing the ambr™250 technologies we have reduced strain generation from six to four weeks.
