- 1) a)What is affinity chromatography and what is it used for? b) A drug called Bamlanivimab is used to treat infections with SARS-CoV-2 (Covid-19).This drug was developed by isolating antibodies from the serum of a patient who recovered from Covid-19.What is possibly on the stationary phase in a column used to isolate antibodies to SARS-CoV-2? How are the antibodies eluted off the column to isolate them for drug development?In normal-phase HPLC chromatography, the stationary phase is polar and the mobile phase is nonpolar. In the reversed phase we have just the opposite; the stationary phase is nonpolar and the mobile phase is polar. Describe molecules in which move faster or slower in each case.Please propose a chromatography-based strategy to purify human insulin proteins that have been expressed in bacterial cells.
