Developing recombinant proteins that closely match their native biological counterparts remains a key challenge in biomanufacturing. Human prolactin (hPRL), a complex protein with clinically and scientifically relevant functions, provides an ideal model for evaluating emerging expression platforms. Through comprehensive physico-chemical and biological characterization, this technical note examines fly-derived hPRL and compares its structural and functional attributes with recombinant hPRL produced in both E. coli and HEK293 systems.

Key analyses explore protein integrity, glycosylation profiles, molecular characteristics, and biological activity, offering insight into how expression host selection can influence final product quality. The findings highlight important considerations for researchers seeking alternatives to conventional production platforms, particularly for proteins that depend on eukaryotic processing pathways.

Explore the data to better understand the relationship between protein expression systems and recombinant protein performance.
