Research guides & handling notes
Practical laboratory writing on reconstitution, storage, certificates of analysis and the compound classes we supply. Written for qualified researchers working with unlicensed reference standards.
How to reconstitute lyophilised peptides
Step-by-step laboratory guide to reconstituting lyophilised reference peptides with bacteriostatic water, including volume calculations and handling errors to avoid.
Read the guide →Peptide storage and stability in the laboratory
How to store lyophilised and reconstituted research peptides: temperature ranges, light and moisture control, freeze-thaw limits and realistic shelf-life expectations.
Read the guide →How to read a peptide certificate of analysis
What HPLC purity, LC-MS identity confirmation and net peptide content actually mean on a certificate of analysis, and how to tell a per-lot certificate from a representative one.
Read the guide →Retatrutide, tirzepatide and semaglutide compared
How the single, dual and triple incretin receptor agonist references differ by target, structure and analytical behaviour - a comparison for laboratory method work.
Read the guide →BPC-157 and TB-500 in regeneration research
What BPC-157 and TB-500 are, how they differ in origin and mechanism, and why regeneration protocols so often hold both - written for laboratory reference use.
