SS-20 has lower net charge (+2 vs +3), lacks Dmt, and has different residue ordering — resulting in weaker electrostatic driving force for mitochondrial accumulation in cell-based systems and different membrane interaction properties.
Melanotan I (MT-1) and MT-2 are both synthetic melanocortin agonists derived from the same research program, but they are meaningfully different compounds. Choosing the wrong one for your experiment can introduce significant rece…
Intestinal epithelial scratch assay Caco-2, IEC-6 % wound closure at 24-48h Moderate (several studies) Dermal scratch assay HaCaT, primary keratinocytes % wound closure Limited DSS colitis histology Mouse colon tissue Mucosal arc…
Research Notice: This article covers research on KPV research peptide and GHK-KPV research peptide — available from Palmetto Peptides for laboratory use only. Research Use Only Disclaimer: All peptides listed on this page are sol…
SS-02 differs only at position 2 (Tyr vs Dmt). SS-31 Dmt provides higher membrane affinity, greater metabolic stability due to steric blocking of enzymatic access, and stronger cardiolipin affinity in laboratory models. Researche…
Melanocortin receptor binding studies Primary tool Not useful Alpha-MSH required for MCR pharmacology Intestinal inflammation (in vitro, cell culture) Both applicable; different mechanisms Intestinal inflammation (oral animal mod…
Both pathways converge at NF-kB inhibition, but through entirely different upstream mechanisms. This convergence makes them potentially complementary research tools for studying inflammatory signaling from different angles.

Primary effect: Selank → anxiolytic/immunomodulatory; Semax → stimulating/pro-cognitive GABAergic activity: Selank shows indirect GABAergic modulation; Semax does not significantly modulate GABA systems BDNF upregulation: Both in…
The half-life difference between the two analogs is striking: IGF-1 LR3: Estimated half-life of ~20–30 hours in biological systems IGF-1 DES: Estimated half-life of ~20–30 minutes — substantially longer than free native IGF-1 (~1…
