Anti-OSCAR-PE Antibody

Beckman Coulter has launched its IOTest Anti-OSCAR-PE conjugated monoclonal antibody. OSCAR is the first FcR-gamma-associated molecule described on human myeloid dendritic cells, and is an activating molecule involved in antigen capture and presentation that may modulate the response of both innate and adaptive immunity. With the Anti-OSCAR-PE monoclonal antibody, researchers can tag a new antigen that is thought to be implicated in the tolerogenic function of dendritic cells. The pre-formulated, standardized monoclonal antibody is provided in 100-test vials, and is approved for research use only.

Genotyping

 

iPlex Gold assay

Sequenom has launched the latest generation of its multiplex genotyping product, the iPlex Gold assay. The assay enables a typical fine mapping genotyping study for about 3.5 cents per data point by providing routine multiplexing at 36 times per reaction. Depending upon the complexity of the specific assay, the new iPlex Gold assay can multiplex up to 40 times per reaction, which represents customer savings of approximately 25 percent per study compared to the original iPlex assay and improves project efficiency.

Chip2 Array Family Additions

 

Oxford Gene Technology has extended its Chip2 family of ChIP-on-chip microarray products with the addition of four prokaryote species. These include Escherichia coli 0157, Salmonella typhimurium LT2, Salmonella typhimurium SL1344, and Streptomyces coelicolor. The Chip2 microarrays can be used to identify the binding positions of global DNA-binding proteins, analyze changes in a particular protein’s binding under various environmental conditions, and as a model system for gene regulation. Each Chip2 microarray is fabricated using OGT’s in situ synthesis platform and interrogates the genome of interest with a probe density of 22,000 oligonucleotide features. ChIP microarray data generated can then be analyzed in relation to its relative gene position using an OGT-developed ChIP browser.
