Sequence
Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH (43 amino acids; N-terminal acetylated)
Form
Lyophilized white powder (acetate salt form)
Storage
-20 °C for long-term storage; 2–8 °C refrigerated after reconstitution; protect from light and moisture; avoid repeated freeze-thaw cycles
Reconstitution
Reconstitute lyophilized powder with bacteriostatic water. Add solvent slowly down the side of the vial to minimize foaming (the larger 43-amino-acid peptide is more shear-sensitive than smaller peptides). Gently swirl until fully dissolved — do not shake. Store reconstituted vial refrigerated at 2–8 °C and use within 7-14 days. Lyophilized form is stable at -20 °C until expiration. Protect from light.
Compliance
Supplied strictly for in-vitro and laboratory research purposes. Not for human or veterinary use. Not for consumption. Not intended to diagnose, treat, cure, or prevent any disease. By purchasing, the buyer confirms qualification to handle research-grade peptides under applicable laboratory protocols.
