Answer all parts of the following question, showing all workings and reasonings/assumptions. 5. Antibodies immobilised on surfaces are often used to detect proteins or other antibodies that indicate disease, e.g., cancer, cardiovascular disease, infection etc. Antibodies are deposited on a plastic surface so that their concentration is 5x10-12 mol cm—2 (NOTE THE UNITS, THEY ARE 2-DIMENSIONAL, MOLES PER CENTIMENTRE SQUARED RATHER THAT MOLES PER CENTIMETRE CUBED AS YOU WOULD FIND IN SOLUTION!). The surface confined antibodies are to be labelled...
