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.
Students can test the effectiveness of biological and non-biological detergents by observing the removal of images from exposed photographic film. Protease enzymes (alcalase and savinase) are added to enzyme-free washing powder to make up the âtest powderâ.www.ncbe.reading.ac.uk/NCBE/PROTOCOLS/PRACBIOTECH/PDF/wash.pdf. Hole in the jelly. This set of experiments suggests that students test a biological and ordinary washing powder on gelatine, agar, and egg yolk.he agar should not be dissolved by either washing powder because it is made of carbohydrates rather than proteins. www.saasta.ac.za/biosciences/enzymes.html. Breaking stains. This experiment requires a spectrophotometer and casein protein coloured with blue dye.
