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

Biology Laboratory Report 4 Practical 7 Osmosis Name: Diana Baktybayeva Tutorial Group: D Lab Partner: Nurlan Mukazhanov Day: Monday afternoon Date: 17.11.14 Title: Osmosis Introduction. Osmosis is a particular type of passive transport involving the movement of water molecules from the region of low solute concentration to the region of high solute concentration through semi permeable membrane‚ which allows movement of solvent molecules‚ but not solute. The main principle

We can monitor the rate at which a chemical decomposes or the rate at which a chemical substance appears. In this experiment we will be measuring the rate of decomposition of hydrogen dioxide with the following reaction: 2 H202 (aq) 4 2 H20 (l) + 02 (g) We can trap the

SCOPE OF THE STATEMENT Concepts Statement no. 7 includes general principles that govern accountants’ use of present value‚ especially when the amount of future cash flows‚ their timing‚ or both‚ are uncertain. This might happen when a business sells an asset and receives payments over time. The statement is limited to measurement issues (how much) and does not address recognition issues (when or if). It does not specify when fresh-start measurements are appropriate. Rather‚ FASB expects to decide

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

Then tip the cylinder to about 45 degrees then put sample into it slowly‚ DON’T spill any water or have to restart. Make sure no air bubbles are clinging. Then take down final volume of water cylinder. 6. Dump the water out‚ then dry sample off. 7. Repeat this over with the other metal samples. * Hypothesis: * My hypothesis is that even though I will find the densities and names of the unknown metals its not going to be accurate because some water will spill out.
