Novatein Biosciences supports researchers who need a protein that is not available in a catalog with its custom recombinant protein expression and purification service (NB-SC101).
The customer provides the accession number or the amino acid sequence of the target gene. Novatein Biosciences performs codon optimization and cDNA synthesis free of charge, then clones the cDNA into an expression vector for a bacterial, yeast, baculoviral or mammalian host. The sequence is verified by DNA sequencing.
The target gene is expressed under optimized conditions, and expression level and integrity are checked by SDS-PAGE and/or Western blot. The protein is then purified by column chromatography (affinity and gel filtration) and identified by SDS-PAGE and immunoblot. Mass spectrometry can be added for an additional charge.
Researchers can also send their own expression vector to start production, or send protein preparations for further purification. Related services include expression optimization, stable isotope labeling, and refolding or purification from inclusion bodies.
