Making light work of ELISA

Melanie™ 9 is a comprehensive easy-to-use software solution for the visualization, matching, detection, quantitation, and analysis of 2D gel electrophoresis (2DE) and Western blot images.

Amersham™ brand Typhoon™ laser-scanner platform provides exceptional data quality through extremely sensitive detection, high image resolution, and a very broad linear dynamic range. These versatile imaging systems support multiple imaging modes, including phosphor imaging, red/green/blue (RGB) and long and short wavelengths of near infrared fluorescence (NIR), as well as optical densitometry (OD) of proteins in stained gels.…

Target Sufficiency® is the ability of a target system to respond to a therapeutic. It reflects the abundance and forms of the drug target protein, as well as other key system proteins that connect the target to disease phenotypes and enable response. Assessment of the target system requires an analysis platform that can simultaneously capture multiple precise protein measurements.

Challenges are welcome. When you are confident.

The H2A.X Phosphorylation Assay Kit (Flow cytometry) is a cell based assay formatted for flow cytometric detection of levels of phosphorylated Histone H2A.X. Cells are cultured in microplates, treated with agents that induce DNA damage or apoptosis, which stimulates H2A.X phosphorylation. Cells are then fixed and permeabilized in preparation for staining and detection. Histone H2A.X phosphorylated at serine 139 is detected by…
