are you hoping to elicit from the candidate? | The candidate should demonstrate a great sensitivity to laboratory precautions and therefore that ability must start right from the onset of laboratory experiment. The candidate is expected to give an answer that will ensure that the laboratory will be a safe place to stay in from the arrival time and also the period the experiment is planned to last. | 3) Interview Question: | What makes you consider yourself to be a qualified Science laboratory

Byakhya Lamichhaney Immunology lab 03/13/13 Answer the following questions: 1) Describe the mechanism of indirect ELISA. Why is ELISA so sensitive? The indirect ELISA maintains the following mechanism wherein the antigen which needs to test for first is added on to every well of the microtiter plate. Then a solution which contains the non reactive protein like casein or the bovine serum albumin is introduced to stop any further changes that had not drawn the interest protein‚ which is called

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are
