PE-22-28
PE-22-28 is a synthetic heptapeptide corresponding to residues 22–28 of spadin, a naturally occurring peptide fragment derived from the sortilin propeptide. The sequence represents a shortened analogue of the parent peptide. PE-22-28 is produced via solid-phase peptide synthesis (SPPS) and supplied as a lyophilized powder intended exclusively for controlled in-vitro laboratory research by qualified professionals. This product is not formulated for clinical, diagnostic, or therapeutic use.
