Courtesy of BD Biosciences Pharmingen  COLOR CODING: Multiplexed bead-based assays, like BD Biosciences' Cytometric Bead Array (shown), test for multiple analytes in a single vial. The key is in the colors: one hue indicates the bead ID, and the intensity of the second, how much protein has been captured. In today's fast-paced research environment, technologies for speedy, cost-efficient analyses reign supreme. As part of this general trend, techniques for multiplexing, that is, simultan
The Array of Today

Human Arrays Human Arrays (continued) A 20th century scientist may have spent an entire career studying the function of a single protein, never imagining that one day it would be possible to study every human gene at once. This capability comes in the form of a microarray, a surface collection of immobilized genes that can be simultaneously examined with specialized equipment.1 Many current applications of arrays, also known as biochips, can be used in functional genomics as scientists seek ch

Investment Author:Holly Ahern If you were to ask several life scientists to name a particular biochemical product that they simply could not do without, you'd probably get a myriad of answers that would mirror the research interests of the group you questioned. A molecular evolutionist trying to differentiate two closely related species of monkeys by restriction fragment-length polymorphism (RFLP) analysis might cite restriction enzymes, which can cut DNA into pieces of varying length.
