The western blot analyze what proteins and how much of the protein are in a gel. A western blot is very sensitive to proteins with histidine or HIS tags. Anything that contains histidine will show up in the gel. The western blot is evidence to whether or not if IL-8 is in the gel. The importances of the western blot is to show how well the proteins reacts to a disease. The first step for a western blot is to run an unstained PAGE gel. Western blot uses gel electrophoresis or electrical to arrange

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 *

Colon Cancer Scenario Introduction: Gel electrophoresis is an important molecular biology tool: it enables us to study DNA. It can be used to determine the sequence of nitrogen bases‚ the size of an insertion or deletion‚ or the presence of a point mutation; it can also be used to distinguish between variable sized alleles at a single locus and to assess the quality and quantity of DNA present in a sample. Gel electrophoresis is a method of separating chemical compounds and molecules by their size

Going Up "Easy as Goo Pie" Goal: 4 goos OCD: Collect 11 or more goos. Goo Types: Black The pipe is located directly above the starting structure. All you have to do is build a tower to reach the pipe and the remaining goos will be sucked in. In order to get the OCD‚ you must only use three goos to complete the tower. Just make sure to place each goo as high as you can so that the third goo can be pulled in by the suction of the pipe. To tell if you are placing the goo high enough‚ the white

Hamlet Revenge: A Chain Reaction In the play Hamlet‚ by William Shakespeare‚ the theme of revenge is repeated numerous times throughout the play and involves a great deal of characters. Of these characters‚ eight are dead by the end of the play by result of murder which was initiated through revenge. Shakespeare uses the revenge theme to create conflict among many characters. Shakespeare uses the revenge theme to create conflict between

experiment that would test if the Taq amount is suitable for the PCR reaction to run correctly. INTRODUCTION Thermus aquaticus (Taq) DNA Polymerase is a bacterium that lives in thermophilic conditions and has been identified as an enzyme able to withstand the protein-denaturing conditions (high temperature) required during PCR (Noronha & Mullins‚ 1992). Why might you not be getting any bands on your PCR? If the Taq DNA polymerase concentration is too low‚ not all DNA fragments will be fully replicated

Biochemical Prospective of DNA polymerase in Replication Biologists and chemists have long recognized a relationship among DNA‚ RNA‚ and protein‚ and this recognition has guided a vast amount of research over the past decades and generations. The pathway of DNA to RNA and RNA to protein is conserved in all forms of life and is often called the Central Dogma. DNA functions as a storage molecule‚ holding genetic information for the lifetime of a cellular organism‚ and allowing that information
