High-Yield System Developed for Efficient Recombinant Peptide Production

Peptides are increasingly recognized for their therapeutic potential, but their production often faces challenges related to yield and cost. Traditional chemical synthesis can be expensive and limited for longer peptides, while existing recombinant expression systems may struggle with peptide stability and solubility. This study addresses the critical need for an optimized, high-yield recombinant expression system to overcome these production bottlenecks.

The newly developed system demonstrated significantly improved peptide production efficiency compared to conventional methods. The optimized system achieved a remarkable yield of 150 mg/L of purified recombinant peptide, representing a 2.5-fold increase over previous standard protocols. Analysis showed that 95% of the expressed peptide was in the soluble fraction, greatly simplifying purification and reducing aggregation issues. Furthermore, the purification process resulted in >98% purity of the target peptide, confirmed by mass spectrometry and SDS-PAGE. This high yield and purity were consistently observed across multiple experimental batches, with a standard deviation of less than 5%.
