Each time the microscope is to be used it should be set up correctly to give a good image. Most often users forget to adjust the iris diaphragm and focus the condenser to give its optimum performance, this could result in objects in the preparation being undetected. There are many microscope set up procedu ...

Alpha Factor Arrest and ReleaseAlpha factor stock is 10-3 M in 0.1N HCl (i.e. resuspend 5 mg alpha factor in 2.97 ml 0.1N HCl). To arrest BAR1 strains, the pheromone should be diluted to a final concentration of approximately 3 x 10�5 M, while bar1 strains require much lower pheromone concentrations (10-8M). To ...
