Lyophilization: why peptides ship as a powder
Freeze-drying is not just water removal — it changes the stability maths, and it explains most of the handling rules.
Research notes
Category: Analytical Methods
HPLC, mass spectrometry, and how purity is actually measured.
Recordkeeping for research-use materials
What to log at intake, why lot traceability matters more than it seems, and how to make an audit boring.
Why we publish every lot, including the boring ones
Selective transparency is marketing. What matters is not how many certificates a supplier shows you, but what happens to the one they replace.
Reading an HPLC chromatogram without a chemistry degree
Peaks, retention time, area percent, and the shapes that should make you ask a follow-up question.
Cold chain: what actually degrades a peptide
Temperature gets all the attention, but it is one of four degradation pathways worth designing your storage around.
What a Certificate of Analysis actually tells you
A COA is only as useful as your ability to read it. Here is what each section of ours means, and which numbers are worth scrutinising.
