ProtExtent Biosolutions Pvt. Ltd. (PBPL) specializes in production of recombinant proteins. PBPL has developed a combination of efficient processes involved in expression and purification for achieving cost-effective production of recombinant proteins.

At PBPL, we have the expertise and proven track-record (core team’s combined experience of >30 years) in expression and purification of recombinant proteins using a variety of recombinant protein expression platforms.

As a flagship in-house R&D program, PBPL is developing a novel and versatile Virus Like Particle (VLP) based platform amenable to highly efficient bioconjugation (essentially in a ‘plug-n-display’ format) with different antigens of choice for improving their immunogenicity. The roadmap involving different business interests of PBPL is shown schematically in the figure below.

PBPL provides Contract Research Services to various requirements in process developments requirements involving optimization of expression, purification and scale-up of recombinant proteins.

PBPL conductsother aligned in-house R&D activities for producing recombinant industrial enzymes and cost-effective biotherapeutics .
