How to Read a Peptide Certificate of Analysis (COA)
A Certificate of Analysis is the paper trail behind a research material. This guide walks through each field on a typical peptide COA and what it does, and does not, tell you.
BPC-157 vs TB-500 in Preclinical Research
BPC-157 and TB-500 are two of the most frequently studied peptides in preclinical tissue research. They differ in origin, structure and the pathways researchers investigate.
How to Reconstitute Lyophilized Peptides for Lab Use
Most research peptides ship as a freeze-dried powder. Reconstituting it carefully protects the material and keeps your experimental results consistent.
What HPLC Purity Testing Measures (and What It Does Not)
"99% pure" is the most quoted number on a peptide listing. Here is how that number is produced by HPLC, and what it can and cannot tell a researcher.
How to Store Research Peptides: Lyophilized and Reconstituted
Peptides degrade through oxidation, hydrolysis and aggregation. Good storage practice slows all three and keeps experimental material consistent from the first run to the last.
