Key sterile technique principles: work in a clean, draft-free area; wash hands thoroughly; use alcohol wipes on all vial tops and injection sites; use sterile, single-use needles and syringes; never touch needle tips or allow them to contact non-sterile surfaces; use a 0.22-micron filter syringe (Whatman-style) to additionally filter reconstituted compounds before use; discard opened sterile water vials promptly; refrigerate reconstituted peptides. Sterility failures in research settings can introduce bacteria and endotoxins — the primary preventable source of injection-site infections and systemic reactions.
