Pre-Lab Lab Unit 03 - Mounting and 1 Simple Stains (Attempt 1 ) Alexis Levine Microbiology Lab T/R 24 January 2010 Introduction: The reason for biological staining is to increase the differentiation of microorganisms when using the light microscope. The use of dyes is used to help people see and study the tiny organisms better. If there was not dyes and we did not have the ability to use a microscope studying different specimen would be much more difficult than it is today. Staining is a necessity when studying microbiology. To better contrast from the bright light microscope dyes and stains are used. Before staining a specimen you have to first make sure it is immobilized. If they weren’t immobilized they would wipe/drift right off the slide because they are liquid. Simple staining and differential staining are the two most significant types of staining procedures frequently used in microbiology. Simple staining and differential staining are two different types of staining techniques.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
