Protein Production

Protein production is the biotechnological process of generating a specific protein. It is typically manipulating the gene expression in an organism. The expression includes the transcription of the recombinant DNA to messenger RNA (mRNA), the translation of mRNA into polypeptide chains, which are ultimately folded into functional proteins and may be targeted to specific subcellular or extracellular locations.

BOC Sciences supports all steps of protein production including the mutagenesis and cloning of target genes in expression vectors, the heterologous expression in prokaryotic and eukaryotic hosts, as well as the subsequent purification of the corresponding proteins as a service. We have a range of state-of-the-art equipment for the producing of recombinant proteins, including high-throughput cloning and large-scale purification from bacteria, insect and mammalian cells.
