INTRODUCTION Shaving gel is a viscous‚ clear gel preparation which is applied before shaving in order to soften the beard‚ lubricate the passage of razor over the face and moisturize the skin. Gels have cross-linked system which exhibits no flow in steady state. Desired characteristics of a Shaving Gel: * It should be clear and transparent. * It should have thick consistency but flowable. * It should lather easily when applied with brush. * It should give clean‚ fresh and moisturized

Proposal: How should our paper look like? (Total 14-15 pages) In the first part of the paper we will write an introduction and talk the approach we take to write the full paper. (1/2 page) In the second part of our paper we talk about ROIC/Payback period versus the NPV method of project valuations. The bottom-line is that NPV method has definite advantages over the other methods. (2-3 pages) In the third part we show that we will do the project valuation according to the NPV. We introduce

Introduction Methionine and cysteine are both sulphur containing amino acids. Most proteins will contain one‚ or both of them at some point in the polypeptide chain. As such‚ many amino acids contain sulphur in some form‚ which is required in small amounts in the mammalian diet. Methionine has a thioether side chain‚ and cysteine’s contains a thiol group. These side chains exist as free thiols inside the cell‚ and are oxidised causing them to pair up and form disulphide bonds in an extracellular

Fall 2011 Lab Report 3 Name: Luan Nguyen Date: 11-30-11 Lab: Gel Electrophoresis Purpose of this lab: In this laboratory investigation‚ students will analyze hypothetical human DNA using restriction endonucleases and gel electrophoresis to match samples from a crime scene to a suspect. Introduction: Your analysis unit will use gel electrophoresis to determine the guilty party. Electrophoresis is a technology in science that allows an individual to separate molecules

Premium DNA Fingerprint DNA profiling
Aim: The aim of this experiment is to investigate the process of Electrophoresis and successfully analyse DNA fragments. Hypothesis: That the experiment will show the visual representation of DNA proteins‚ and that the shorter the band the further is will travel. Background: Restriction enzymes are DNA-cutting enzymes found in bacteria‚ which cut DNA into smaller fragments. A restriction enzyme recognizes and cuts DNA only at a particular sequence of nucleotides‚ known as restriction sites

Aim: The objectives of this experiment are: Become more familiar with using micropipettes. Use restriction enzymes to cut DNA at specific sites. Use Ligase to rejoin some of the cut/separated DNA fragments. Learn to separate DNA using electrophoresis. Introduction: Restriction enzymes are proteins which cut dsDNA at specific regions depending on the enzyme used‚ determined by the nucleotide sequence of the DNA‚ i.e. each enzyme recognises specific nucleic acid sequence of 4‚6‚8 nucleotides

method of Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE) was conducted using a negatively charged protein and pre-stained molecular weight markers. The hypothesis was that the molecular weight of N-acetyl-β-D-hexosaminidase B would be 28‚000 kDa. To confirm or reject the hypothesis‚ the molecular weight of N-acetyl-β-D-hexosaminidase B and the concentration of protein had to be determined. The electrophoresis of the protein gel were conducted using a Hoefer SE 600 Ruby at 30

endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments across the gel is based on the size and charge of the fragment. After the fragments have been run in the gel‚ they are stained with methylene blue and viewed on a light box. This allows the DNA bands to be viewed on the gel. Introduction
