Compound handling sheets

Storage and sensitivity, compound by compound

Sheets exist only where the handling advice can be supported by published data or by well-understood sequence chemistry. Each one states which.

BPC-157 Handling Sheet Partly documented Body Protection Compound 157, PL 14736, bepecin Powder−20 °C Solution−20 °C A 15-residue, proline-rich, acidic peptide with no methionine, cysteine or tryptophan. Chemically one of the more robust research peptides; the main solution… TB-500 / Thymosin β4 Handling Sheet Partly documented Thymosin beta-4, Tβ4, TMSB4X (gene); "TB-500" in research catalogues Powder−20 °C Solution−20 °C A 43-residue acetylated peptide with a single methionine that oxidizes readily. "TB-500" is used for both full-length thymosin β4 and a short… GHK-Cu (Copper Tripeptide) Handling Sheet Partly documented Copper peptide, glycyl-L-histidyl-L-lysine copper complex, prezatide copper Powder−20 °C Solution−20 °C A tripeptide complexed with copper(II). The metal changes the handling rules: avoid chelating agents and reducing agents, protect from light, and expect… Semax Handling Sheet Inferred from structure ACTH(4–7)-Pro-Gly-Pro, Met-Glu-His-Phe-Pro-Gly-Pro Powder−20 °C Solution−20 °C A seven-residue peptide built on the ACTH(4–7) fragment with a Pro-Gly-Pro extension. Its N-terminal methionine is the main stability concern. Selank Handling Sheet Inferred from structure Thr-Lys-Pro-Arg-Pro-Gly-Pro, tuftsin analogue Powder−20 °C Solution−20 °C A seven-residue, proline-rich, basic peptide derived from tuftsin. It has no residues that are especially prone to oxidation or deamidation, so standard… Epitalon Handling Sheet Inferred from structure Epithalon, Epithalone, AEDG peptide Powder−20 °C Solution−20 °C A tetrapeptide, Ala-Glu-Asp-Gly, whose Asp-Gly pair is one of the fastest-isomerizing motifs in peptide chemistry. Dry storage is straightforward; solutions need care. MOTS-c Handling Sheet Inferred from structure Mitochondrial open reading frame of the 12S rRNA type-c Powder−20 °C Solution−80 °C A 16-residue mitochondrial-derived peptide with two methionines, a tryptophan and two tyrosines. It is the most oxidation- and light-sensitive peptide in this… Ipamorelin Handling Sheet Inferred from structure NNC 26-0161 Powder−20 °C Solution−20 °C A five-residue synthetic peptide containing non-natural amino acids (Aib, D-2-naphthylalanine, D-phenylalanine) and a C-terminal amide. Standard storage applies, with light protection for…
