Protocol for High-Throughput Screening of Neural Cell or Brain Tissue Protein Using a Dot-Blot Technique with Near-Infrared Imaging.

Dot blotting allows for the rapid screening of a larger number of samples and/or targets than more traditional methods, such as a western blot or in-tissue-based methods. We have developed a dot-blot assay specifically for use with a LiCor Odyssey CLx imager, which allows for sensitive detection of proteins in the infrared range. Here, we provide a detailed protocol for the preparation of brain tissue and neural cell culture lysates for analysis of protein targets by dot blotting.
