Fish phylogenetic tree based on protein size Amanda Reed Lab partners: Lecia Redwine‚ Kyle Hatcher TA: Baneshwar Singh Biology 117‚ Section 25 Tuesday 10:30 AM Introduction Although tree diagrams have been used since the days of Charles Darwin‚ biologists have only recently adopted the tree model of evolution to read and interpret phylogenies. One of the reasons for this is the confusion that often arises from using a tree model to describe a phylogeny (Baum‚ 2008a). Many people interpret

Estimation of protein concentration Introduction Protein assays are designed to measure the total protein in a solution. Protein assays are quantitative if the protein to be assayed is available in sufficient quantity such that one is able to use it to create a standard curve. If this cannot be achieved‚ then a standard protein‚ such as albumin‚ may be used for a standard curve with the understanding that the results on the unknown protein are semi-quantitative. Since most proteins are not available

Analysis of protein post-translational modifications using DIGE-based proteomics Robert M. DeKroon‚ Jennifer B. Robinette‚ Cristina Osorio‚ Sun Yong Jeong‚ Eric Hamlett‚ Mihaela Mocanu and Oscar Alzate Summary Difference gel electrophoresis (DIGE) is most often used to assess relative changes in the expression levels of individual proteins in multiple complex samples‚ and this information is valuable in making inferences about relative protein activity. However‚ a protein‟s activity is not

lactose‚ proteins‚ and minerals. Curds are a solid dairy product achieved by the curdling‚ or coagulation‚ of milk. Historically‚ curds are most often used in the production of cheese. Curds are achieved by the denaturing of proteins in milk‚ particularly caseins‚ which is a protein group that helps with the development of children and young

Brittney Humphries. Title: Testing for the Presence of Starches‚ and Proteins Purpose: To test for the presence of starches and protein macromolecules‚ to introduce the concept of variations in chemical compounds. Hypothesis: If biuret is blue after a test for protein‚ then it is a negative result because biuret reagent is blue to begin with. If a solution is pinkish purple‚ or purple‚ then the test for protein is positive. The test solution for starches is yellowish brown. If any substance

The Spectrophotometer Determination Of Protein Concentrations And The Effects Sodium Dodecyl Sulphate And Triton X-100 Have On Protein Concentration. INTRODUCTION Spectroscopy is used as a collective term for all the analytical techniques based on the interaction of light and matter. Spectrophotometry is one of the branches of spectroscopy where we measure the absorption of light by molecules that are in a gas or vapour state or dissolved molecules/ions (Tombs‚ et.al‚ 1959). Spectroscopy is the

Cheese lab Introduction Scientists work to create new and improved versions of cheese-curdling enzymes‚ as well as to improve the yields and qualities of cheeses. Modern-day cheese makers want to produce large amounts of high-quality cheese in the most economical way. Purpose ▪ Determine which curdling agent produces cheese the fastest. ▪ Determine which curdling agent produces the most cheese. ▪ Examine numerical data to support predictions. ▪ Examine variables that can

Experiment 2 Quantification of Proteins in Solution by Spectrophotometer Lab bench# 1 Introduction: Absorption spectroscopy is a common method for finding the concentration of proteins or protein complexes in a solution. Proteins absorb light at specific wavelengths and can be defined by the equation A = log (Io/I). This equation states that an absorbance at a specific wavelength‚ A is equal to the log of the ratio of incident light intensity (Io)‚ to transmitted light intensity (I). A
