What does reconstituting peptides mean?

Reconstituting peptides means mixing lyophilized (freeze-dried) peptide powder with bacteriostatic water or sterile water to create a liquid solution suitable for research use. This process is essential for preparing peptides for laboratory applications.

What do I need to reconstitute peptides?

You need: lyophilized peptide vial, bacteriostatic water (0.9% benzyl alcohol), sterile syringes, alcohol swabs, and a clean workspace. All materials should be sterile to maintain peptide integrity for research purposes.

How much water should I use to reconstitute peptides?

The amount of bacteriostatic water depends on your desired concentration. Common ratios include 1ml, 2ml, or 3ml of water per vial. Calculate based on the peptide dosage in your research protocol to achieve the appropriate concentration.

How do I store reconstituted peptides?

Reconstituted peptides should be stored in the refrigerator at 2-8°C (36-46°F). Most reconstituted peptides remain stable for 2-4 weeks when refrigerated. Lyophilized peptides should be stored in the freezer at -20°C until reconstitution.

Can I shake the peptide vial after adding water?

No, never shake peptide vials. Shaking can damage the peptide structure. Instead, gently swirl the vial or let it sit in the refrigerator until the powder fully dissolves. This preserves peptide integrity for research applications.

Where can I buy bacteriostatic water in Canada?

Webber Science supplies bacteriostatic water along with research-grade peptides to qualified researchers in Canada. All supplies are intended for laboratory research purposes only.
