Reliable data begins long before the first assay. How a lyophilized peptide is reconstituted, how the solution is stored, which solvent is drawn into the syringe and how the accompanying paperwork is read — each of these steps decides whether a batch behaves as its certificate says it should. These guides collect the laboratory practices we consider baseline for anyone working with research peptides.
Each guide is written for a research setting: bench technique, concentration arithmetic and documentation. None of it is usage advice, and none of it changes the nature of these products — they are reagents, nothing more.
Materials, mg/ml calculations from the solvent volume you choose, aseptic technique, and the handling errors — shaking above all — that quietly degrade a sample.
What HPLC purity and mass-spectrometry identity each prove, what “≥ 99%” actually means, why third-party testing matters, and the red flags of a certificate that proves nothing.
Lyophilized versus reconstituted, the three temperature regimes, light and freeze–thaw risks, and a labeling habit that saves entire experiments — with a summary table.
What 0.9% benzyl alcohol does, how bacteriostatic water differs from sterile water, and why it is the standard solvent for multiple-withdrawal preparations at the bench.
Practical questions about ordering, shipping to our ten supported countries, or our testing program are covered in the FAQ. Batch documentation lives on the Certificates of Analysis page, where independent Janoshik Analytical results are being published as batches are tested. For the analytical background — synthesis, HPLC, mass spectrometry — see the Science page.
