Physical Properties
DSIP is a short-chain synthetic peptide composed of nine amino acids. Its compact structure supports strong aqueous solubility and efficient laboratory handling under controlled research conditions. As a small peptide, DSIP is susceptible to enzymatic degradation when exposed to biological systems, making lyophilized storage and cold-chain handling important for preserving structural integrity. Protection from moisture, light, and repeated freeze–thaw cycles helps maintain analytical consistency during laboratory use.
