WebThe eluted solution is then titrated with a standard NaOH solution to the first equivalence point. Experimentally it required 11.06 mL of a 0.182 M NaOH solution to reach the first equivalence point. Calculate the number of moles of K + in the weighted sample. Calculate the mass (grams) of K + in the weighted sample.
WebAug 15, 2024 · It is possible to change the elution conditions by manipulating the pH or the ionic strength of the binding ligand. This method is often used in biochemistry in the purification of proteins. The ligand tag is bonded and after separation the tag is then removed and the and the pure protein is obtained. WebThe eluted solutions from the column, after gel separation, are collected in different fractions and analysed by UV-Vis absorption. The dye/protein ratio (D/P) of the bioconjugate can be determined by the absorption spectra of the labelled proteins, according to the relationship reported in equation 1 [ 18 ] and represents the average number of ...
