PetaGene of Seoul, South Korea, has introduced the

Peta-array

tissue microarrays. The microarrays are glass slide-based arrays containing tissue sections with spots ranging from 0.6 to 2.0 microns. Each tissue section is extracted from donor blocks and transferred into a recipient block — either formalin-fixed paraffin-embedded blocks, or frozen.

The company uses a semi-automated tissue microarraying process for quality control. The product includes clinical information including patient age and sex, medical history, and follow-up data.

The company sells normal and cancer tissue microarrays.

PetaGene is a joint venture between the petrochemical company Isu Chemical and Yonsei University Medical Center of Seoul. PetaGene is focusing on genetic testing, drug screening service for individualized anticancer chemotherapy, and novel drug target and biomarker discovery using antibody and proteomics tools. Isu was founded in 1969 to produce alkyl benzene for detergents. The company is branching into biochemistry, concentrating on monoclonal antibodies and protein therapeutics.

 

Applied Biosystems has introduced a line of chemistry to isolate DNA from plant and animal tissues.

The company said NucPrep chemistry, can purify 96 samples of DNA in under three hours. The product is optimized for the ABI Prism 6100 nucleic acid prep station and the ABI Prism 6700 automated nucleic acid workstation. The kit includes a 96-well genomic DNA purification tray with application-specific membrane, 96-well tissue pre-filter tray, digestion buffer, proteinase K, DNA purification solution, wash solution, and elution buffers.
