Algenex’ core expertise is in the production of subunit vaccines using Baculovirus vectors.

CrisBio® harnesses pupae from the Trichoplusia ni as living bioreactors to take recombinant protein production to the next level.

Pupae are "programmed" to produce recombinant proteins by inoculation with a virus containing Algenex' improved expression cassette TopBac®.

CrisBio® and Topbac® are propietary, patent protected technologies which can be applied in combination or on a stand-alone basis.

CrisBio®

Current production methods for recombinant proteins present a series of challenges in respect to development speed, scalability, technical complexity and cost.

CrisBio®, is an automated process that enables productivity of gram/litre levels with an extremely low investment and the upside of production flexibility and immediate scalability.

CrisBio® is a simple and robust process that has proven efficient in producing complex antigens.
CrisBio® uses pupae from the Trichoplusia ni, the natural host of the AcMNPV baculovirus vector used in the commercial vaccine production.

TopBac®

TopBac®

TopBac® consists in a proprietary patented expression cassette composed by several genetic regulatory elements working in cascade. When incorporated into the genome of a baculovirus vector, TopBac® significantly improves the productivity and quality of recombinant proteins produced by host cells.

TopBac® is fully compatible with the most common baculovirus vector-based production technologies, consistently providing increase in production yields in insect cells significantly above current industry standards. TopBac® has also demonstrated its capacity to improve product quality by reducing foreign protein proteolysis. TopBac® has been tested for the production of a variety of proteins in insect cells and in combination with CrisBio®, significantly increasing productivities in both platforms.
