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.
The pins and edge connectors came from 2 old computer motherboards and a few sticks of computer memory. There is gold to be found in computer parts but usually it's just a very thin coating ... still, gold is gold ! To dissolve the metal contaminants, we need to use a 50/50 mixture of nitric acid and water. The amount of nitric acid required will be approximately 20 mls mixed with approximately 20 mls of water. Using the plastic pipette, the water is added first followed by the nitric acid.
