The purity and sterility of bacteriostatic water are essential to prevent contamination & preserve dissolved peptides' shelf-life. Push the pin through the rubber stopper at an angle so that bacteriostatic water is injected into the vial's interior wall rather than directly onto the powder. We should keep the peptide solution at 4°C & the lyophilized peptide at -20°C. Once reconstituted, do not freeze.
