PerkinElmer, Beckman Coulter

PerkinElmer last week launched its Constitutional Chip 4.0 microarray for array-based comparative genomic hybridization.
 
The new tool is a bacterial artificial chromosome array intended for identification of chromosomal gain or loss of DNA and identification of the region in which gain or loss has occurred. Specifically, the chip contains more than 5,000 BAC clones covering 25 percent of the human genome; 90 well-characterized chromosomal regions covered by more than 1,200 BAC clones; improved subtelomere coverage; and high-resolution detection of chromosomal gains and losses across the X chromosome.
 
The Constitutional Chip 4.0 is designed to be used with PE’s aCGH reagents, ScanArray scanners and image processing software, and SpectralWare aCGH analysis software.
 

 
Beckman Coulter last week launched the Agencourt DNAdvance System, a new extraction kit for DNA isolation and purification from mammalian tissue samples. 
 
The system incorporates Beckman’s Solid Phase Reversible Immobilization paramagnetic bead-based, nucleic acid purification technology. The Agencourt DNAdvance chemistry is also automated on the Beckman Coulter Biomek NXP and FXP Laboratory Automation Workstations.
