The Virtual Lab – ELISA Test Lab: Immunology 09/04/2013 Instructors: Dr. Charlie Wilson Written by: Dipen Patel I. Objective: The purpose of the lab was to learn the procedure of performing an ELISA test to determine whether a particular antibody is present in a patient’s blood sample. ELISA is an abbreviation for “Enzyme-linked Immunosorbent Assay." II. Introduction: The interaction of antigen and antibody outside the body can be used to determine if patient

flask with an iodine crystal with a bromobenzene solution with a stir bar. Once the stirring began‚ the solution turned brown and over time began to lighten up. The color change to brown indicated that the reaction began and this is why an iodine crystal was placed in the solution. The reaction started to boil due to its own reflux so heat didn’t need to be applied. Next the anhydrous ether solution was added very slowly in a dropwise manner with a needle through the septum cap on the condenser. This

There are many different ingredients in a kitchen that causes a chemical reaction with baking soda. This experiment was designed to test 4 kitchen ingredients(Omega oil‚ water‚ lemon juice‚ and vinegar) mixed with baking soda‚ to see which one will cause a balloon to expand. It was hypothesized that baking soda mixed with lemon juice and vinegar would cause the balloon to expand. Using these ideals the experiment was completed and the data was recorded. It was decided that the hypothesis was correct

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Abstract The “Chemical Kinetics” experiment was done to investigate the changes in the rate of reaction under the effect of concentration‚ temperature‚ and presence of a catalyst. It was determined that as the concentration of reactants and the temperature increases‚ the rate of the reaction increases as well. Also‚ the reaction was run by the presence of catalyst‚ and the rate of the reaction increased drastically in the presence of it. The order of the reaction with respect to each reactant

Experiment 5 In the first part of this lab‚ the objective was to get the molar concentration of sodium hydroxide by using the secondary standard‚ sodium hydroxide solution with the primary standard‚ potassium hydrogen phthalate. With this information‚ we could create a second derivative plot‚ which can be used to obtain the exact concentration of the secondary standard‚ sodium hydroxide. Also‚ the indicator can give us these results along with the end points and with the readings from the pH meter;
