1. Combination of protoplast transient expression system and Nickel resin based purification is an useful approach for chromatin enrichment that can be used to identify transcription factor’s potential target genes. 2.Comparison our ChIP-on-chip target genes with in vivo binding targets using two whole genome tiling array platforms showing high degree of overlap between two methods.

Here we present a novel discovery-oriented high-throughput approach to the screening of allergen reactivates in crude biological extracts is presented using seafood allergens as an example. The CPGR workflow permits the effective screening of hundreds of putative allergens in parallel using minute amounts of patient serum and constitutes a cost-efficient allergen-specific antibody screening method for a routine diagnostic setting.

Apoptosis Inducing Novel microRNA for Breast cancer and Hepatocellular Carcinoma

MicroRNA provides a mechanism to target cancer stem cells and restraint tumors cells permanently; this could lead to promising cancer therapeutics and imaging agents. Apoptosis inducing microRNA was identified to target HCC and breast cancer cells for imaging and therapy.

A Novel Fluorimetric Assay for the Detection of TACE (a-Secretase)

AnaSpec, Inc.

To facilitate high throughput screening of TACE inhibitors, AnaSpec synthesized a novel peptide substrate for TACE using QXL™ 520/5-FAM FRET pair. Using this FRET substrate, AnaSpec developed a new kit – the SensoLyte™ 520 TACE Activity Assay. This kit can be used to detect the activity of the enzyme and for screening of TACE inhibitors. It is highly sensitive and can detect subnanogram amounts of enzyme.

High Content Image Analysis using a Laser Scanning Microplate Cytometer
Paul Wylie, Ben Schenker, Sarah Payne and Andrew Goulter, TTP Labtech

Microscope-based high-content instruments offer high optical resolution, however, the limited field of view afforded by their objective lenses can mean lengthy read times for some assays, especially where multiple image capture per well is required. Wherever possible, only a small percentage of the total number of cells present in a test well are analysed to keep plate read times at a minimum, which may not always be ideal. Microplate laser- scanning cytometers, such as TTP LabTech’s Acumen® eX3

A genome-wide loss of function screen identifies new genes required for lung cancer cell proliferation

RNA interference (RNAi) provides an experimental tool for functional genomics analysis. We screened a genome-wide RNAi library to identify new genes involved in lung cancer cell proliferation. 72 % from the 257 genes identified were involved in general gene expression processes, 16 % were of unknown function or unrelated to proliferation, and 12% consisted of uncharacterized genes. These last sets of genes provide potential novel targets for lung cancer treatment.
