For almost all research applications involving peptides like IGF-1 LR3, this is impractical and wasteful
Rather than working with multiple individual preparations, investigators may choose combination formulations when consistency and defined composition are important parts of a research protocol
At 9,111 Da with three disulfide bonds (C6-C48, C18-C61, C47-C52) essential for receptor binding, IGF-1 LR3 is a folded protein that can irreversibly denature under conditions that small peptides tolerate easily, including vigorous vortexing, repeated freeze-thaw cycles, room temperature exposure exceeding 30 minutes, and adsorption to untreated plastic surfaces

If you are comparing a Jessner peel vs TCA peel, you are probably trying to answer a few practical questions at once: Which one gives stronger results
