Gel filtration GEL FILTRATION OF PROTIENS Aim: The aim of this experiment is to identify proteins from a complex mixture using the gel filtration technique also known as size exclusion chromatography. This technique is widely used by biochemists when proteins larger than the pores are excluded from the column and the smaller molecules elute last and then collected in test tubes for examination by spectroscopic techniques. The red/brown proteins‚ in particular‚ will be observed closely

visualize DNA molecules and determine their length by using a technique called gel electrophoresis. Introduction to gel electrophoresis In gel electrophoresis‚ DNA fragments move through a porous matrix made of agarose‚ a gelatin-like substance purified from seaweed. The agarose is melted like Jell-O and then ® poured into a plastic tray to harden into a slab called a gel. A plastic comb inserted at one end while the gel is hardening forms wells where DNA samples can be placed. The DNA is mixed

Laura Gallagher Partner: Rob Einersen Biology Period D Mr. Alvarez 15 February 2013 Gel Electrophoresis Introduction: Agarose Gel Electrophoresis is a process in which the process of determining whether a strand of DNA is either positively or negatively charged. The container in which the gel is stored has a negative and positive side; whichever side the DNA molecules go to means the DNA is charged the opposite way. (Ware‚ Lunte‚ Gardiner)For example if a DNA molecule

Gel Electrophoresis Lab SBI4U1 May 13th‚ 2013 Gel Electrophoresis Lab Purpose: The purpose of this lab is to learn how restriction enzymes cut DNA molecules at specific sequences‚ thus producing DNA fragments of various lengths. Students learn how fragments form unique patterns‚ which help to distinguish the base for DNA identification. This lab answers the question “whose DNA was left behind?”. Materials: * Transfer pipets * Agarose Gel * Dyed DNA samples *

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
