Expression Pathology, NEC

Premium

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.


NEC announced this week that it has begun shipping BioPrism, a support system for proteomic analysis. The system helps researchers to examine proteomics data by displaying multiple analytical data and information stored in public databases on PCs, and compiling a database of samples used in analysis.

The system ranges from 3 million yen ($28,000) for the compact model to 5 million yen ($46,700) for the high-end model. NEC said it expects to sell 100 BioPrism units over the next three years.
