Category: Compound Identity

A longer sequence than most in this catalogue, N-terminally acetylated, and easily confused with the thymosin beta family. An identification reference.

Semax is the heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro, about 814 g/mol. Sequence, the methionine oxidation impurity to look for, and how to verify a vial.

Epithalon is the tetrapeptide Ala-Glu-Asp-Gly (AEDG), about 390 g/mol. Sequence, the related short peptides, HPLC behaviour and verification.

Sermorelin denotes a specific 29-residue amide. Understanding its relationship to the modified GRF analogues clarifies a category where names overlap heavily.

The three letters in brackets change the molecule, its mass and its analysis. The distinction that causes the most ordering errors in this category.

Ipamorelin contains residues that do not appear in proteins, and that is the most important thing to know when confirming its identity. A reference.

GHK-Cu is a metal complex, not simply a tripeptide, and that changes how it must be handled analytically. An identification reference.

TB-500 is a name that gets applied to more than one thing. An identification reference for what it denotes, and why the distinction matters when you order.

An identity reference for BPC-157: sequence, nomenclature, and the analytical characteristics that shape how it behaves on a column.
