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

effect on heart rate‚ using the freshwater crustacean‚ Daphnia magna‚ as the experimental subject. For humans‚ alcohol works as a depressant‚ slowing down the heart rate of the consumer; caffeine works as a stimulant‚ increasing the heart rate of the consumer. The heart depends on an internal pacemaker system to keep it pumping consistently and at the right speed. Alcohol disturbs this pacemaker system and causes the heart to beat irregularly. Studies show that caffeine consumption raises blood pressure

Exercise affects all people differently‚ specifically a person’s heart rate and blood pressure. After exercising your heart rate should increase and your blood pressure should decrease (Blood Pressure Association‚ 2008). The purpose of this lab was to determine which level of exercise would have the greatest impact on affected pulse and blood pressure. In this lab we tested how exercise affected heart rate by testing a random group of people with different body types and exercise levels to see how

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

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Hypertension (63 yr old) Hypertension or high blood pressure is a common disorder when blood pressure remains abnormally high 140/90 or greater for a period of time and doesn’t go down. Seniors with high blood pressure‚ a single specific cause is not known. Factors that can raise blood pressure are eating too much salt‚ drinking too much alcohol‚ not excising‚ taking certain medicines‚ having long lasting stress‚ and smoking. If high blood pressure is not brought down to normal it can have serious

Exploring Rates‚ Equilibrium‚ and Organic Chemistry Brandon Sher SCH 4U For: Ms. Merhai Due date: June 1st‚2013 Introduction: Organic chemistry. Two quantities one could measure with the presence of organic chemicals are chemical equilibrium and rate of reaction. Chemical equilibrium is the ratio between the forward and reverse process of a reaction. This is represented by the equation: K = products / reactants. When a reaction has reached equilibrium‚ the

Practical 1.1 Introduction: Caffeine belongs to a class of compounds called methylxanthines and can block a receptor on the surface of heart muscle cells for adenosine. In fact‚ it is caffeine’s blockade of the A1 adenosine receptor in the heart that causes the heart to pound after a significant caffeine dose. Caffeine and similar compounds also inhibit a class of enzymes known as cyclic nucleotide phosphodiesterases. These enzymes are‚ in part responsible for degrading a stimulatory signal produced
