For Best Results. Apply the Upper Brush against the top lashes and sweep from root to tip until a clean, voluminous look is achieved, followed by the lower lash line using the Micro Brush. Do not let dry between coats. Removes with soap and water or with MaybellineÂ® Clean Express!Â® Eye Makeup Remover.
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 simple particle model is less helpful in explaining why there is a limit to the solubility of any material or why the solubility varies at different temperature. Although we most commonly think of dissolving solids in water other liquids can act as solvents. Nail varnish remover is used to dissolve nail varnish and, white spirit to dissolve some kinds of paint and petrol is a good solvent for grease. Many non water solvents are not really suitable for use with primary children.
