Transgenic plant systems for the expression of mammalian antibodies offer opportunities for the study of plant metabolism and development. Agricultural production could provide virtually unlimited quantities of any antibody.
The Federation of American Societies for Experimental Biology (FASEB) annual meeting will be held in Washington, DC, next week. A micro-osmotic pump for slow-release drug delivery and a vertical tube gel apparatus will be among the many exhibits.
A set of 'chopstick" electrodes for measuring membrane potential, a portable pH meter and a pulsed electrochemical detector — measuring devices for improved accuracy.
By sensitively monitoring the metabolic rates of living cells, a novel instrument detects cellular responses to stimuli as diverse as ligand-receptor binding and toxic chemicals.
With over 800 exhibitors, next week's Pittsburgh Conference in New York will unveil the latest and the best in spectroscopic and analytical instrumentation: an electrophoretic light-scatteringspectrophotometer, a biocompatible HPLC system and much more.
Silver stains offer high sensitivity for the detection of proteins and DNA separated on gels and membranes. These stains depend on the reduction of ionic to metallic silver.
Products for electrophoresis described this week include a 1- and 2-D gel analysis system, a temperature gradient gel electrophoresis system and an all-in-one crosslinker/transilluminator.
Addressing the limitations associated with first-generation robotics, the authors describe the emergence of second-generation machines based on an 'open architecture' with more built-in flexibilty.
This week's focus on instruments designed to improve liquid handling tasks range from dual-action thermomixers to complex robotic sample processors and manipulative robot arms.
Products featured at next week's Bio/Technology Winter Symposium in Miami, Florida, include a high-throughput DNA sequencer and an antibody purification system.
The solutions to many protein analytical problems require flexible chemistries at a high sensitivity. Solid-phase sequence analysis is one way to eliminate limitations inherent in current methods.
