Working with Proteins
Knowledge Now in Experimental Biology: Working with Proteins is a new six-part laboratory video series that fills a gap in the tools available for teaching students the fundamentals of working with proteins. Through a lively mixture of lab bench demonstrations, vivid scientific animations, and interviews with researchers, this series offers a memorable introduction to many of the most important tools in the modern research biologist's toolkit.The first video in this series covers basic principles and demonstrates laboratory techniques for lysing a cell, separating cellular components by preparative centrifugation, and purifying and concentrating a fraction containing a protein of interest by ammonium sulfate precipitation.Video Two details three of the most common chromatographic approaches used to isolate a protein of interest from a crude cell extract: Gel filtration chromatography, ion exchange chromatography, and affinity chromatography. Video Three describes how SDS-polyacrylamide gel electrophoresis is used to estimate the monomer molecular weights by measuring the migration of denatured molecules in an electric field.The fourth video lays out a strategy for designing a good activity assay, emphasizing criteria that must be met to yield valid results. Video Five examines the wide range of techniques now available for analyzing protein primary structure.The final video focuses on how researchers determine the three-dimensional structure of proteins.

"Having taught a laboratory course in cell fractionation and protein separation, I could only wish the Working with proteins videotapes had been available for me at the time to make the difficult protocols and complex experiments understandable for my students and to help them see the process of science as well as the practical steps in the activities." --Wayne C. Carley, Executive Director, National Association of Biology Teachers Working with Proteins is an integrated presentation of six 20-minute programs on some of the major techniques and methods used in the isolation, purification, and characterization of proteins. Each program is narrated by a noted protein chemist and his or her laboratory staff." --SCIENCE BOOKS & FILM
