Preimplantation Genetic Diagnosis: The Next Big Thing?
Ricki Lewis | Nov 12, 2000 | 9 min read
Courtesy of David Hill, ART Reproductive Center Inc.Two separated blastomeres subjected to FISH analysis to check the chromosomes. In early October, preimplantation genetic diagnosis (PGD) made headlines when a Colorado couple used assisted reproductive technology (ART) to have a baby named Adam, whose umbilical cord stem cells could cure his six-year-old sister Molly's Fanconi anemia.1 When Adam Nash was a ball of blastomere cells, researchers at the Reproductive Genetics Institute at Illinois

Cell-free Transcription and Translation
Gregory Smutzer | Jan 7, 2001 | 8 min read
In Vitro Translation Systems Researchers synthesize recombinant proteins in cell-free extracts to verify the identity of cloned genes, to study protein-protein, protein-nucleic acid, and protein-drug interactions, and to carry out mutagenesis studies. In vitro protein translation studies rely on the efficient and selective transcription of cloned genes in vitro, which is now not only possible, but also routine, thanks to the identification of bacteriophage (phage) DNA-dependent RNA polymerases a

DEINO-MITE CLEANUP In 1956, investigators discovered a potentially invaluable cleanup tool in an unlikely place. A hardy bacterium called Deinococcus radiodurans unexpectedly thrived in samples of canned meat thought to be sterilized by gamma radiation. The b
