The Lab Blog
Research education, lab technique, and compound science — new posts on the regular.
A laboratory-handling guide to peptide reconstitution: research diluents, why solvent runs down the vial wall, and how dissolution beats aggregation.
Learn how lyophilization (freeze-drying) works, why removing water stabilizes lyophilized peptides, and why the freeze-dried cake is the standard form for research.
Learn to read an HPLC chromatogram: main peak, retention time, baseline, impurity peaks, and how peptide purity is calculated from peak area.
Peptide mass spectrometry explained: how labs confirm identity by matching expected vs observed mass, why MS complements HPLC, and how it supports research integrity.
A lab best-practices guide to peptide storage: lyophilized vs reconstituted handling, freeze-thaw damage, light and moisture control, and cold-chain shipping.
A research-focused look at peptide degradation: how oxidation, hydrolysis, deamidation, and aggregation break peptides down and show up in analytical testing.
A clear peptide chemistry primer: amino acids, peptide bonds, N- and C-termini, and how a sequence defines a research peptide's structure. Research use only.
A researcher's overview of solid-phase peptide synthesis (SPPS): resin, coupling, deprotection, cleavage, and how method shapes final peptide purity.
A research-use primer on peptide molecular weight, molarity vs. mass concentration, and the dilution math labs use to plan reference standards.
A material-science comparison of bacteriostatic water and sterile water as research diluents: benzyl alcohol chemistry, solution stability, and reconstitution.
A research-use-only survey of research compound categories: signaling peptides, growth-factor mimetics, fragments, cyclic vs linear, tagged, and standards.
A peptide purity percentage rarely means what it looks like. Learn how chromatographic purity, net peptide content, salts and solvents differ.
Learn what endotoxins are, why low-endotoxin research materials matter for cell-based work, how LAL testing works, and how sterility ties to a COA.
A lab guide to sterile technique and contamination control for peptide research vials: clean-area handling, stopper wiping, and protecting data integrity.
How lot numbers, labeling standards, and documentation build research peptide traceability from supplier to bench, and why it underpins reproducibility.
A lab-workflow guide to reproducible peptide research: controls, standardized protocols, detailed notebooks, consistent handling, and retaining COAs with data.
