Beyond Film: Laboratory Imagers
Jorge Cortese | Apr 1, 2002 | 9 min read
Years ago, researchers had only one data-imaging option: autoradiography. These scientists tagged samples—whether nucleic acid, protein, cell, or tissue—with radioactive labels, and captured images on film. Safety concerns, convenience, and sensitivity, spurred the development of alternative techniques, and today, researchers can choose from a range of options, including fluorescence, chemifluorescence, and chemiluminescence, in addition to autoradiography. Fluorescence occurs when

Turmoil Besets Wistar In Wake Of Koprowski's Ouster
Jean Wallace | Mar 1, 1992 | 10+ min read
The Wistar Institute in Philadelphia marks its 100th anniversary this year, but the mood at the nation's oldest independent biomedical research facility is hardly jubilant. The institute has been in turmoil for the last year, after the abrupt ouster of longtime director Hilary Koprowski, the famed virologist and immunologist who transformed Wistar from a dilapidated museum into a world-renowned research center. The commotion recently was stirred up further, when the 75-year-old Koprowski file
Pursuing Proteomes
Deborah Wilkinson | Jun 11, 2000 | 9 min read
Bio-Rad's PROTEAN® IEF System provides 2-D electrophoretic separation as part of the ProteomeWorks System Australian postdoctoral fellow Marc Wilkins coined the term "proteome" in the mid-'90s, referring to the total set of proteins expressed in a given cell at a given time. The term took hold, and a new scientific discipline was born. In proteomic studies, all the proteins from a given cell, organelle, or tissue are analyzed simultaneously with respect to properties such as expression leve
Oligos To Go! : Purveyors of Custom Oligos
Jim Kling | Mar 29, 1998 | 7 min read
Date: March 30, 1998 Author: Jim Kling Table of Vendors So--the boss calls you into her office and tells you it's time to find another supplier of oligonucleotides. The custom house you've been using just went out of business, or maybe your team is preparing to delve into a new research project that calls for oligos. You scan the ads in several journals and do a quick internet search. Before you know it you've got a 'short' list of 50-100 suppliers. Wading through a sea of suppliers to find th

Date: September 15, 1997 Comparison Chart HPLC is an essential work-horse for most bio-laboratories. Without a functioning system, the days of gravity columns-once a not-so-fond, distant memory-can return with a vengeance. And a system that no longer fits your research needs can collect dust like so much scrap metal. In choosing an instrument, consider the demands your research will place on it. For example, determine what type of solvents you will most often use. Solvent compatibility of th
