Research peptides from ChinaPeptides are supplied exclusively for scientific research. They are not intended for clinical, diagnostic, veterinary or direct human use.
Typical applications include receptor studies, immunoassay development, proteomics standards and mechanism-of-action research in academic and industrial laboratories.
A research peptide can arrive as a catalog item when the classical sequence is listed, or as a custom project when the sequence, termini or labels are unique. Both paths use the same research-use restriction and the same expectation of HPLC and mass-spectrometric documentation.
If you are comparing suppliers, send the sequence, purity and the assay. A cheaper crude lot is not equivalent to a ≥95% HPLC lot when the impurity profile can bind the same receptor or stain the same blot.
