The professional development program consists of three modules listed below: Module 1 - Refresher on Solution Preparation During this lab based module participants will rediscover the joys of molarity and volume/volume vs. weight/volume percentage concentrations as they relate to preparing and using stock solutions. The day will culminate in an iodine clock competition to crown the master solution maker. Module 2 Real- Time PCR During this lab based module participants will learn the principles of polymerase chain reaction (PCR) the parameters and many of the applications and variations. The lab component will have the participants conduct a Real-Time PCR reaction designed to identify if grain based foods are derived from genetically modified crops. Participants will perform gel electrophoresis on the product of the Real-Time PCR and compare results present in the gel image to those obtained through the Real-Time analysis. A melt curve will be conducted as part of the Real-Time PCR analysis, the interpretation of which will also be discussed. Module 3 Introduction to Chromatography During this lab based module participants will learn the principles behind chromatography as well as the theory of the various separation chemistries used such as ion exchange, hydrophobic interaction, normal and reverse phase chromatography. The laboratory component will consist of participants conducting thin layer chromatography to separate pigments extracted from spinach and exploring the impact of mobile phase composition on migration of components. An additional lab will be conducted using an Ultra-Performance Liquid Chromatography (UPLC) system to analyze coffee or tea samples for their caffeine content. Sample preparation for this lab will be conducted using Solid Phase Extraction (SPE) columns.
