Panorama Ab Microarray Cell Signaling kit: a unique tool for protein expression analysis.

Antibody arrays are a promising new tool for mass analysis of protein level changes in cells responding to different stimuli. Here we describe a novel antibody array system called Panorama Ab Microarray Cell Signaling, that contains 224 antibodies spotted on FAST nitrocellulose-coated slides that can detect protein levels as low as a few nanograms per mL. The antibodies spotted are specific for proteins important in various areas of cell signaling such as phosphorylation, cell cycle, apoptosis, nuclear signaling and cytoskeleton proteins.
