BD Biosciences Clontech has released a new DNA amplification product called BD Taq Full DNA Polymerase. The enzyme is a full-length recombinant version of the Thermus aquaticus strain YT1 DNA polymerase. It can amplify DNA from any template and is recommended by the company for any general PCR amplification procedure. The product claims to be highly efficient and sensitive, allowing scientists to use less enzyme and template in each reaction. It is also available with a hot start antibody.


GE Healthcare has added a new array to its CodeLink series, the ADME Rat 16-Assay bioarray. The gene-expression array has a multi-assay chamber that allows up to 16 samples to be processed in parallel on every slide. Each slide has 16 arrays, containing over 1,200 oligonucleotide probes each targeting rat genes involved in drug absorption, distribution, metabolism, and excretion processes. This is the first CodeLink catalog product that offers 16 assays per slide. It is compatible with existing CodeLink instruments, reagents, and accessories.

GE Healthcare has also upgraded its CodeLink Expression Analysis Software. Version 4.1 is now available and compatible with the new bioarray.


Koada Technology has released Koadarray V2.4, a software package that it claims offers automated analysis and quantification of array images. The Scottish firm said that that V2.4 eliminates user intervention in microarray analysis, making the interpretation of data more reliable and objective.


Researchers at Stanford University released an updated version of Java Treeview, a cross platform, open-source program for microarray data visualization, last week.
