Sonication can be used to enhance solubility. 1  First, assign a value of â1 to each acidic residue (Asp [D], Glu [E], and the C-terminal âCOOH). 2  If the overall charge of the peptide is positive, the peptide is basic. 3  If the overall charge of the peptide is negative, the peptide is acidic. Acidic peptides might be soluble in PBS (pH 7.4). If this fails, add a small amount of basic solvent such as 0.1 M ammonium bicarbonate to dissolve the peptide, and then add water to the desired concentration.
These peptides act as a signal to tell your skin it was damaged and to make new collagen. Applying peptides directly to your skin is a way to trick your skin into thinking that it has lost collagen recently and needs to make more. The most popular signal peptide for cosmetic use is palmitoyl pentapeptide (Matrixyl). It can be found in many peptide skin products and might be effective in improving the appearance of fine lines. Be a smart skin care consumer â you can find this active ingredient in Strivectin and many other expensive peptide creams.
