Exotic Species, Locales All In Day's Work For Conservation Biologists
Karen Young Kreeger | Jan 22, 1995 | 9 min read
Traveling to the ends of the earth in pursuit of biological quarry is not part of the job description for the average molecular biologist. But for anthropologist Don Melnick, going to work means trekking through the jungles of Southeast Asia for blood samples from the Javan silvery gibbon and other endangered animals. And the jobs of geneticist John Avise and biologist Brian Bowen entail long nights on tropical beaches waiting for nesting sea turtles. The following are the top ecology journal

All's Well that Ends Well: A Profile of Specialty Microwell Plates
Brent Johnson | Sep 26, 1999 | 10+ min read
Date: September 27, 1999Table of Specialty Microplates The story of the microplate is one of those tales of history that either has been forgotten or was never clearly understood. According to Barry Lazar of Dynex Technologies, formerly Dynatech Laboratories, the origin of what is now commonly referred to by Dynex's registered trademark of Microtiter plates began with Gyola Takatsy, a Hungarian-born scientist who was trying to scale down serology tests. His first prototype became available in 1
Surpassing the Law of Averages

By Jeffrey M. Perkel Surpassing the Law of Averages How to expose the behaviors of genes, RNA, proteins, and metabolites in single cells. By necessity or convenience, almost everything we know about biochemistry and molecular biology derives from bulk behavior: From gene regulation to Michaelis-Menten kinetics, we understand biology in terms of what the “average” cell in a population does. But, as Jonathan Weissman of the University of Califo

Reagents That Distinguish Th1 and Th2 cells Courtesy of R&D SystemsSchematic representation of cytokines influencing the development of antigen-activated naive CD4+ T cells into Th1 and Th2 cells. Editor's note: Although individual techniques are associated with specific researchers in this article, it should be noted that these investigators commonly use several different techniques to analyze T lymphocyte populations. The human body is constantly under siege. It must defend itself fr
Premade cDNA Libraries

Suppliers of Whole-organism cDNA Libraries Suppliers of Tissue-specific cDNA Libraries The questions of gene function, interaction, and regulation are central to the science of molecular biology. Despite the myriad of new technologies, products, and techniques produced by the genomics revolution, some old standards remain just as useful as ever. One such technology is the cDNA (complementary DNA) library. The sheer number of companies offering premade and custom cDNA libraries and products th
