Storing lyophilised peptides: a laboratory guide
Storage conditions for lyophilised research peptides before and after reconstitution: temperature, light, moisture, freeze-thaw, aliquoting and how long each form keeps. Laboratory guidance only.
Bacteriostatic water vs sterile water: what the label means
Bacteriostatic water contains 0.9% benzyl alcohol and can be drawn from for 28 days; sterile water has no preservative and is single-use. What each is, when a laboratory…
What “99% HPLC purity” actually means
