Expression Pathology introduced last week its patent-pending Liquid Tissue MS Protein Prep Kit which allows for the extraction of proteins directly from formalin-fixed paraffin-embedded tissue. After extraction, proteins can be submitted for direct analysis by mass spectrometry.

Each kit contains reagents and materials to prepare four samples. The kit can be used with macro or microdissected tissue samples. A detection range of several hundred to over 1,000 proteins has been demonstrated from a single FFPE tissue experiment.
