e incorporated a fusion tag prior to our genes of interest and attached the expressed fusion proteins covalently on microarrays. This enhances the specific binding of the proteins compared to nitrocellulose. Thus‚ it helps to reduce the number of false positives significantly. It enables us to screen for immunogenic proteins in a shorter The correct insert size was determined by Colony PCR. Plasmids from clones containing the correct-sized inserts were isolated and the MCS was sequenced using both

Expression and Purification of Human Platelet-Derived Growth Factor Beta (PDGF-B) Rachel C. Hermina-Stewart* and Elsie I. Parés-Matos† *Industrial Biotechnology Program‚ †Department of Chemistry University of Puerto Rico-Mayagüez Campus rachel.hermina@upr.edu December 14‚ 2009 ABSTRACT. Platelet-Derived Growth Factor (PDGF) is one of many proteins that regulate cellular growth and division. The PDGF family consists mainly of five different isoforms called as PDGF-A‚ PDGF-B‚ PDGF-C and PDGF-D. Three

Student Handout: Create A DNA Fingerprint Name: Kevin Lee From the video: 1. What evidence might kidnapped children leave behind that would contain their DNA? Food‚ Drinks‚ Cigarrets‚ lolipops‚ anything they touched. 2. How easily do you think DNA evidence can be contaminated? Dna evidence can be contaminated when DNA from an outside source gets mixed up with the DNA tested 3. How does a forensic department avoid confusing DNA profiles in a contaminated sample? They profile the lab workers

development. The originator does not need to worry about retaining ownership of his individual conceptions. As an example‚ the theories of Ferran Adria‚ the great Spanish chef‚ have been shared the world over through his books and the media‚ and his molecular gastronomy cuisine concept has been copied by many young restaurateurs and chefs. Of course‚ this led him to halt his business operations and look for more original ideas. I remember the CNN interview in which he said he did not have any new concept

a) Breeding Farmers have always used selective breeding to produce animals that exhibit desired traits (e.g.‚ increased milk production‚ high growth rate). Traditional breeding is a time-consuming‚ difficult task. When technology using molecular biology was developed‚ it became possible to develop traits in animals in a shorter time and with more precision. In addition‚ it offers the farmer an easy way to increase yields. Scientists can improve the size of livestock genetically.

Name: Tan Tee Hng Class: MB1102 Module: Molecular Genetics Date: 6th January 2013 Circadian Rhythms From this experiment‚ using transgenic fly that can glow in the dark‚ a study of circadian rhythms was performed. Circadian Rhythm is like an internal body clock(biological clock) of an animal. And results obtained from experiment conducted with transgenic glowing fly‚ allowed one to come up with a few hypotheses‚ firstly‚ circadian rhythm repeats every 24 hours. When the glowing flies were placed
