The total protein content was estimated as proposed by Lowry et al. A bovine serum albumin stock solution (1mg/ml) was prepared in sodium hydroxide (1N). Five different concentrations (0.2‚ 0.4‚ 0.6‚ 0.8‚ 1 ml) of the prepared solution were taken in different test tubes. In another set of test tubes‚ 0.1 and 0.2 ml of the extract were taken. In each test tube‚ the volume was made up to 1 ml‚ followed by addition of the prepared alkaline solution (5 ml) at room temperature. The solutions were left

purpose of this lab was to find the theoretical and experimental percentage yields of the double displacement reaction between the solutions Lead (II) Nitrate (PbNO3) and Potassium Iodide (KI). It is important to obtain amounts of Lead (II) Nitrate and Potassium Iodide as close to 1.44g as possible. This reaction creates Lead (II) Iodide and Potassium Nitrate. The precipitate during this reaction is Lead (II) Iodide. The balanced equation is Pb(NO3)2 + 2KI= PbI2 + 2KNO3. In this lab the Lead (II) Iodide

March 18‚ 2012 Title: Types of Chemical Reactions Data: Reaction Observations Evidence #1 It turned a reddish brown and the liquid went clear. The color change proved it was a chemical change. #2 The reaction turned yellow and it separated and created a fog. The solid formed precipitation and had a color change during the reaction proving it to be a chemical change. #3 There was green smoke and the crystals turned black. The green liquid turned dark green and continued to sizzle with

Abstract The experiment is to identify the guilty suspect that is present at the crime scene by comparing with the DNA samples. Polymerase Chain Reaction(PCR) is used to amplify the small amount of Deoxyribonucleic Acid (DNA) for forensic or genetic studies‚ which require necessary product and placed in the thermal cycle. Gel electrophoresis is being run in order to analyze and compare the DNA samples at the crime scene with the guilty suspects. Gel electrophoresis is used to separate DNA using

Labs 4 & 5 Lab Four: Experiment 1 1. At what magnification do you first notice the ragweed pollen? I first noticed it when the magnification is at about 30 2. Which is bigger‚ rhinovirus or E. Coli? E. Coli is bigger 3. Based on the magnification‚ how many of the E. Coli can fit into the same space as the head of a pin? 10‚000 E. Coli 4. About how many red blood cells could fit across the diameter of a human hair. (Again‚ look at the magnification scale)? About 100 blood cells
