PEPTIDES PREFER THE COLD
Keep peptide vials refrigerated at all times to reduce peptide bond breakdown. DO NOT FREEZE. Most peptides, especially shorter ones, can be preserved for weeks if careful.
Always swab the top of the vial with an alcohol wipe, rubbing alcohol or 95% ethanol before use.
Before drawing solution from any dissolved peptide vial, fill the pin with air to the same measurement you will be filling with solution, ie. if you plan to take 0.1 ml, first fill the pin with 0.1ml of air, push the air into the vial, and then draw the peptide back up to the 0.1 ml marker. Doing so will maintain even pressure in the vial. Always remember to remove air bubbles from the pin by flicking it gently, needle side up, and pushing bubbles out. In addition, push out a tiny amount of solution to ensure there is no air left in the metal tip.
ONLY MIX WITH STERILE BACTERIOSTATIC WATER
The purity and sterility of bacteriostatic water are essential to prevent contamination and to preserve the shelf-life of dissolved peptides.
Push the pin through the rubber stopper at a slight angle, so that you inject the bacteriostatic water toward the inside wall of the vial, not directly onto the powder.
Lyophilized peptide should be stored at -20°C (freezer), and the reconstituted peptide solution at 4°C (refrigerated). Do not freeze once reconstituted.
NEVER SHAKE A VIAL TO MIX.
Air bubbles are unfavorable to the stability of proteins.
