Harm Reduction & Laboratory Standards
Critical handling rules to maintain peptide peptide chain integrity and prevent bacterial colonization.
Diluent Selection: BAC vs SWFI
Bacteriostatic Water contains 0.9% benzyl alcohol as a bacteriostatic preservative, allowing multi-dose vial stability for 21-28 days at 2-8°C. Sterile Water (SWFI) lacks preservatives and must be used or discarded within 24 hours.
The 45° Sidewall Trickle Rule
Never inject diluent directly onto the fragile lyophilized peptide cake. Always angle the needle against the glass inner sidewall, allowing liquid to trickle down passively to avoid shearing tertiary molecular peptide structures.
Cold Chain & Freeze-Thaw Integrity
Store lyophilized vials at -20°C for up to 24-36 months. Once reconstituted, refrigerate at 2-8°C. Never subject reconstituted peptide solutions to repeated freeze-thaw cycles; divide into single-use cryogenic aliquots if freezing is required.
Analytical Quality Verification
Reliable in-vitro research requires third-party RP-HPLC purity testing (target: ≥98.0%) and Mass Spectrometry (MALDI-TOF / ESI-MS) to verify molecular weight against degradation adducts, deamidation, and truncations.
