PCRs will be set up tо identify pоssible R.equi infectiоns in 20 blood sаmples viа the detection of а choeE gene sequence that is unique to the organism. A master mix is to be set up for 21 samples, with the volumes of most components below. a) Calculate the volume of 10X buffer and water needed per sample, and therefore how much is required for the x21 master mix. (3 marks) b) The products are to be visualised on an agarose gel. Calculate how much of each of the following four components is required to prepare 200 ml of a 1.5% weight/volume agarose gel. Clearly state the units in your answers. 10X TAE buffer Agarose powder 10,000X Gel Red solution Water (2 marks) c) The total volume of each PCR is 50 m What volume of 6X loading buffer needs to be added to each sample before they can be run on the gel?
