GeneChip Human Exon 1.0 ST Array
Affymetrix has announced the launch of the GeneChip Human Exon 1.0 ST Array, offering whole-genome, exon-level expression profiling on a single array for the first time. Designed to interrogate approximately 1 million exons, the array helps researchers better understand the roles that alternative splicing and gene expression play in biology. Each Affymetrix exon array has a capacity of more than 6 million data points, so whole-genome exon expression analysis is possible on a single array.
High-Definition CGH Microarrays
Agilent Technologies has introduced an updated microarray-based Comparative Genomic Hybridization platform featuring high-definition CGH microarrays. Agilent’s HD-CGH custom microarrays and related probe design services allow researchers to draw upon the company’s database of approximately 4 million pre-designed and computationally validated CGH probes and do high-resolution tiling of regions of interest at 10 to 100 times higher resolution.
The Human Genome CGH Microarray has also been updated with a new probe set based on the latest genome build to further expand the coverage. This microarray contains approximately 43,000 60-mer oligonucleotide probes, empirically validated in multiple model systems that span coding and non-coding sequences with an average spatial resolution of 35kb. Platform enhancements also include reagents and analytics software updates.
GeneChip 500K Array Set
The GeneChip 500K Array Set is the latest in a line of genetic analysis products from Affymetrix. The 500K Set examines more SNPs than any other available genotyping solution, allowing higher resolution to find the genes associated with complex disease. The 500K is also the first product to utilize the output of the International HapMap Project — SNPs from the 500K Set are publicly available and data gathered using the 500K Set can be analyzed in the context of the emerging HapMap. The set includes optimized and validated reagents based on the GeneChip Mapping Assay, GeneChip DNA analysis software, and the GCS3000 7G Scanner.
Two-color ULS protein labeling and fluorescent detection kits
New ULS labeling kits for protein science applications are available from Kreatech. The two-color ULS protein labeling and fluorescent detection kits can be used for profiling serum and cell lysate samples on high-content antibody arrays and to label both proteins and nucleic acids. The kits offer the ULS labeling molecule bound to biotin and fluorescein for direct labeling of protein analytes in serum and cell lysate samples. Upon incubation on the antibody array, detection is provided by anti-Fluorescein-DY547 and Streptavidin-DY647 conjugate, allowing scanning of the array in the standard Cy3/Cy5 channels.

Novagen StrepoTag System
StrepTag technology improves on the reliable biotin/streptavidin binding specificity and strength. The short StrepoTag II fusion tag (8 amino acids) reduces potential interference with target protein structure or function. StrepoTag II binds to StrepoTactin protein nearly 100 times tighter than the biotin/streptavidin interaction, but elutes in gentle, physiological conditions. Rapid, one-step affinity purification results in active fusion proteins with greater than 95% purity. The system includes StrepoTag II vectors, a wide range of StrepoTactin affinity purification resins, hardware, and buffers, and StrepoTag detection reagents.
