The release of the decoded genome for Plasmodium falciparum (the most deadly malaria parasite) in October represented a momentous step forward for the people of Africa. Around the same time, Abdoulaye Djimde, the head of the epidemiology and immunology department a

Date: February 15, 1999Table of Robotic Liquid Handler Manufacturers and Table of Pipetting Robots Cytotoxicity studies, ELISA assays, apoptosis assays, peptide library screening--these and many other assays are now performed without human intervention by automated liquid handling systems. Continuing evolution of these machines has produced some very capable and powerful robots, increasing assay throughput to dramatic levels. In this profile, LabConsumer examines the automated liquid handler
The Hidden Side of Sex

Sexual selection doesn’t end when females choose a mate. Females and males of many animal species employ an array of tactics to stack the deck in their reproductive favor.
Taking The Measure Of The Message
Laura De Francesco | Nov 22, 1998 | 9 min read
Date: November 23, 1998Product Comparison Getting a measure of even a single RNA species has never been easy. Every few years, a new technique comes along--Northerns, ribonuclease protection assays, RT-PCR--that makes the task only incrementally easier. But a quantum leap in technology took place just a few years ago with the introduction of cDNA arrays, and suddenly not just one but hundreds to thousands of target nucleic acids can be analyzed simultaneously and precisely. Since then, array te
