Overview

Solyn peptides are often supplied as lyophilized powder to support stability in storage and transit. Before use in a research protocol, the powder is reconstituted with an appropriate laboratory diluent. Reconstitution can vary by sequence and protocol. The steps below are general laboratory best practices.

General best practices

• Work in a clean laboratory environment using aseptic technique and appropriate PPE.

• Allow the vial and diluent to reach room temperature to reduce condensation and improve dissolution.

• Add diluent slowly down the inside wall of the vial (avoid forceful injection into the powder).

• Gently swirl or roll the vial until the solution is clear; do not vigorously shake (bubbles and agitation can promote foaming or aggregation).

• Do not exceed the vial’s labeled fill volume; if you need a larger volume, use an appropriately sized container.

If the solution stays cloudy

• Give it time: some sequences dissolve slowly; gentle rolling and a short rest period can help.

• Try a lower-ionic-strength diluent if your workflow allows (some peptides can be sensitive to salts).

• For sequences known to require acidified conditions, a small amount of acidified water may help (consult literature and your lab protocol)
