yeast expression vectors

Utilizing Profacgen's proprietary YeastXceedTM Technology, selected stable and durable production strains that resemble mammalian system are employed for high-yield, high-productivity protein processing, thus dramatically reducing the associated costs and inherent time requirements. HostOptimTM boosts recombinant protein production per cell by increasing the protein per mRNA ratio across a range of eukaryotic production hosts. Other available recombinant production technologies typically target transcription and are limited to specific production systems. HostOptimTM can be used to increase the production yield of your recombinant protein and can be combined with transcription enhancing or other production improving technologies.
