Reconstitution
Peptide Reconstitution
Peptides are stored in a lyophilized (a freeze dried fine powder) state and so need reconstitution before they can be used. Sterile water with a bacteriostatic agent (0.9% Benzyl Alcohol) added is generally (except for IGF1 type peptides, see below) the best choice, as it both extends the storage life of the reconstituted product and also allows multiple doses to be drawn up out of the vial, which is more convenient and cost-effective in a research context. However, for IGF1 DES and IGF1 Long R3, Acetic Acid 0.9% should be used for reconstitution due due to buffering issues and poor solubility when using bacteriostatic water.
Bacteriostatic Water
This is a sterile, nonpyrogenic preparation of water for
injection containing 0.9% (9 mg/mL) of benzyl alcohol added as a bacteriostatic
preservative. It is supplied in a multiple-dose container from which repeated withdrawals
may be made to dilute or dissolve drugs for injection. The pH is 5.7 (4.5 to
7.0).
Acetic Acid
Similar to Ethanol and water, Acetic Acid is a protic (polar) solvent. This means that it dissolves both polar compounds, like salts and sugars, but also non-polar compounds, such as oils.Peptide solubility characteristics vary strongly from one peptide to another. Residues such as Ala, Cys, Ile, Le..
