Neurons Glow in 'Brainbow'
CAMBRIDGE, Mass., Nov. 2, 2007 -- The circuitry of the brain is being imaged as never before thanks to a multicolor fluorescent protein labeling technique called "Brainbow." Brainbow allows researchers to tag neurons with roughly 90 distinct colors, a huge leap over the mere...
Protein Yields Vivid Images
MOSCOW, Aug. 30, 2007 -- A new red fluorescent protein derived from a brilliant red sea anemone purchased in a Moscow pet shop reveals body tissues more vividly than other fluorescent proteins in use today. The protein's developers said the glow it emits can render cancers...
Tiny Implantable Biocomputers Developed
CAMBRIDGE, Mass., May 22, 2007 -- A crucial step has been made toward building biological computers, tiny implantable devices that can monitor the activities and characteristics of human cells. The information provided by these "molecular doctors," constructed entirely of DNA, RNA...
'Revolutionary' NMR Advance
CAMBRIDGE, Mass., May 21, 2007 -- A highly sensitive nuclear magnetic resonance (NMR) approach to detecting the molecular structure of tiny proteins reduces the size of the samples needed so much it might one day diagnose glaucoma from a single teardrop. Currently, NMR requires...
FRET Technique Developed to Observe DNA-Repairing Protein
CHAMPAIGN, Ill., Aug. 15, 2006 -- Researchers have observed the life cycle of RecA, a protein that plays a major role in repairing damaged DNA, by using a highly sensitive, single-molecule fluorescence resonance energy transfer (FRET) technique they developed . A better...
Fluorescent DNA Could Detect Cancer Early, UF & Columbia Researchers Say
Nov 30, 2005 — GAINESVILLE, Fla., & NEW YORK, Nov. 30 —- University of Florida and Columbia University researchers say they are a step closer to a technique to easily detect a wide variety of cancers before symptoms become apparent. The findings involve...
