Agricultural genomics tools company Pyxis Genomics of Chicago, formerly AniGenics, has introduced bovine gene chips. The CattleArray 3800 includes 3,820 selected cDNA clones, printed in duplicate on a single glass slide, including 3,072 placenta ESTs and 748 spleen ESTs. The price is $750 per chip for commercial users, and
$250 for non-commercial users.
PerkinElmer has launched its new MicroMax ASAP RNA labeling kit, which it licensed from Kreatech of the Netherlands. The kit is designed for direct labeling of RNA used in gene expression experiments on glass microarrays, and uses a non-enzymatic system, the Universal Linkage system. In this system, a platinum group forms a coordinative bond with the target to attach the label to the target. They bind to the N7 position of the bases in amino acids.
According to Perkin Elmer, the kit allows researchers to go from RNA labeling to hybridization in under two hours and is straightforward. The kit includes reagents and hybridization buffer for the detection of 25 two-dye microarray experiments.
