Semax Aerosol Kit appears in research contexts involving neuropeptide research, cognitive pathway models, melanocortin-related signaling studies
Furthermore, purified CFE systems by design contain no chaperones and extract-based systems may or may not have sufficient levels of endogenous chaperones to adequately support proper folding, and thus CFE systems are frequently supplemented with additional chaperones (e.g., DnaK/DnaJ/GrpE, GroEL/GroES)
