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

to have in the body. A substrate is the material that is being broken down. In this case‚ the substrate would be hydrogen peroxide. The catalase‚ located in the liver‚ is being used to break down the substrate. Problem The purpose of this lab is to see if the enzyme‚ catalase‚ can be manipulated. We are testing the effects of pH‚ temperature and enzyme concentration. Hypothesis Controlled When we add peroxide to the liver it will bubble a lot and break down faster. When we add peroxide

IS3110 – Risk Management Lab # 9 – Develop recovery back-up procedures and recovery instructions 1. How does documented back-up and recovery procedures help achieve RTO? By having effective backup and recovery procedures you should have the necessary resources to restore systems from backups and a repeatable process that is known to succeed in achieving RTO. By documenting and implementing backup and recovery procedures‚ the process for recovery is much more efficient‚ helping with the time

dish cultures. All kinds of mutants are easily induced and readily obtainable with particular ascospore color mutants. These visual mutants aid in tetrad analysis‚ especially in analysis of intragenic recombination. ( Campbell 72) A common lab use is to observe meiosis and mitosis in the fruiting bodies‚ called perithecia. An interesting feature of S. fimicola is that its fruiting body is phototrophic. Thus‚ as it grows the stalk will bend toward a light source and when the sac bursts‚ the

Introduction: The question investigated in this lab was which drugs have the greatest and least affect on the pulse of the Lumbriculus variegates. Ethanol will cause the worms to become inactive‚ caffeine will cause the worms to become overactive‚ and nicotine will cause the worms to become more active. Lumbriculus variegatus is also known as black worm. This small species of worms currently lives in North America and Europe within marshes and ponds. They survive by eating microorganisms and organic

Friction Page 1 Lab: Friction William Morris Leo Hayes High School Friction Page 2 Purpose: To investigate the coefficient of friction for a given surface and the effects that factors such as weight‚ surface area and changes to the surface have on the coefficient of friction. Hypothesis: The smaller the amount of normal force (weight)‚ the less friction created and the least surface area and the greaser the surface the less friction is created. With

Procedure: Exercise 1: Using the Microscope - Viewing Prepared Slides I started out by reading and reviewed the science lab safety reinforcement Agreement and the instruction to oil immersion lens. After setting up my lab station I view the six prepared slides with 10x and 40x objctives lens. In each slide the differences was magnification and the 40x lans gave a clearer look of the specimen. The observation of slide e

Darwin’s Finches Lab In this inquiry lab‚ we explored natural selection using a laboratory. We wanted to see what was the effect of the type of food available on the frequency of different types of bird beaks. Our hypothesis was that If the type of the food available changes‚ then the frequency of beak types will change‚ because birds with beaks more suited to the available food will be more successful over time. Variables: Independent Variable: type of food available

Samuel Heidenreich Miss.Tatu Biology March 5‚ 2015 Introduction In the Mitosis lab an onion root was observed under a microscope to observe whether or not cell division takes place. Also‚ whether cells replicate in order for it to reproduce. By observing the onion root under the microscope it allows many layers to be looked at through each cell division. The goal of Mitosis is the replication of cells to produce multiple like cells. The steps involved in Mitosis are what is known as

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work
