Problems when growing bacterial cultures for the expression of recombinant proteins at a laboratory scale can include insufficient yield, and quality issues such as poor protein solubility and low activity. Biosilta’s EnPresso B range of reagent-based growth systems typically increase protein yields by five- to 100-fold and improve protein functionality when compared to results using conventional growth media. The products are supplied as pre-sterilized tables, which are simply added to sterile filtered water. Optimized protocols enable researchers to go from pre-culture to harvest within two days, using standard lab equipment such as shake flasks or 24 deep well plates. Biosilta Oy
