Laboratory Reconstitution & Handling Protocol

To maintain sterility and peptide integrity, swab the vial septum with sterile 70% isopropyl alcohol prior to needle insertion. Using a sterile luer-lock syringe (27G to 30G), slowly introduce the diluent into the lyophilized peptide vial by directing the liquid stream down the interior glass wall. Allow the lyophilized powder to dissolve naturally through gentle circular swirling; avoid vigorous shaking or vortexing to prevent protein denaturing. Sealed vials should be stored at room temperature (15°C to 30°C). Post-puncture solutions must be maintained at 2°C to 8°C and utilized within 28 days.

Research Pathways & Profile

Bacteriostatic Water (BAC Water) supplies an analytical-grade, sterile non-pyrogenic reconstitution solvent formulated with 0.9% (9 mg/mL) benzyl alcohol USP. In biochemical and molecular research, it serves as the essential diluent for lyophilized peptides, proteins, and biochemical reagents. The benzyl alcohol bacteriostatic agent suppresses microbial and fungal proliferation across repeated vial access, allowing multi-dose laboratory aliquoting for up to 28 days under refrigerated conditions (2°C to 8°C) without compromising peptide solubility or bio-activity. Supplied strictly for laboratory research and analytical assay evaluation.

Handling, Solvent & Storage Guidelines

Laboratory Reconstitution Protocol: Cleanse vial septum using a sterile 70% isopropyl alcohol prep pad prior to needle puncture. Use a sterile luer-lock syringe (27G to 30G) to draw the required volume. When reconstituting lyophilized peptide vials, aim the needle toward the inner glass wall and introduce solvent slowly, allowing it to trickle down without creating foam. Do not vortex or shake vigorously. Storage: Store sealed vials at room temperature (15°C to 30°C) shielded from direct light. Once punctured, preserve between 2°C and 8°C and utilize within 28 days. Discard if particulate matter, cloudiness, or discoloration is observed. Strictly for laboratory in-vitro investigation only.
