Amersham Biosciences, Affymetrix, Anachem


Amersham Biosciences last week rolled out two new CyDye fluors for protein arrays, specifically formatted for labeling proteins or antibodies for protein array experiments. CyDye kits will contain two vials of Protein Array Grade mono-reactive dye packaged in a color-coded secure container. The kits, one containing protein array grade Cy3 mono-reactive dye, and the other Cy5, will allow researchers to perform either one-color sandwich assays, or multiplexed differential analysis. The volume of dye provided with the new kits is more appropriate for those doing protein arrays than is currently available. The kits contain sufficient dye to label material for 20 to 80 protein array slides. Amersham Biosciences is the only supplier of mono-reactive CyDye fluors. Pricing details were not disclosed.


Affymetrix introduced Barley1, its second plant-genome based GeneChip array (see page 1). The chip has more than 23,000 probes.


Anachem introduced a 24-channel model to its Rainin LTS (light touch tip ejection system) pipette line used for filling 96-well plates. The pipette is available in manual or electronic, 20 µl or 100 µl versions.
