Bio-Rad Launches ProteoMiner Protein Enrichment Kits

Product news

Bio-Rad Laboratories, Inc., a multinational manufacturer and distributor of life science research and clinical diagnostic products, today announced the introduction of its new ProteoMiner® protein enrichments kits, which enable researchers to concentrate and enrich low- and medium-abundance proteins that cannot be detected through traditional methods.

ProteoMiner protein enrichment kits are compatible with a variety of sample types and can be used with most downstream protein analysis techniques including one- or two-dimensional gel electrophoresis, chromatography, and surface-enhanced laser desorption/ionization.

“ProteoMiner kits enable life and pharmaceutical researchers to reduce the complexity of biological samples and detect low-abundance proteins,” said Kate Smith, Bio-Rad’s expression proteomics product manager.

ProteoMiner protein enrichment kits employ a novel bead-based technology, which uses a diverse library of combinatorial peptide ligands to simultaneously dilute high-abundance proteins and concentrate low-abundance proteins. When a complex biological sample is applied to the beads, high-abundance proteins saturate their high affinity ligand(s), and excess protein is washed away. In contrast, low-abundance proteins are concentrated on their specific affinity ligand(s).

To provide flexibility for use with multiple downstream applications, two ProteoMiner protein enrichment kit formats are available. Both are optimized for use with serum and plasma samples, but they may also be used with other sample types with at least 50 mg total protein available.

The ProteoMiner protein enrichment introductory kit, provides columns and all necessary reagents for accessing low-abundance proteins in a variety of biological samples and is compatible with the majority of downstream proteomics applications. This kit can be used to process two samples. The “full-size” kit can be used to process up to ten samples.

The ProteoMiner sequential elution kit is available for researchers who wish to elute their proteins into multiple fractions to detect additional proteins. This kit has been optimized for SELDI experiments and provides columns and reagents for processing up to 10 samples.

The kits are available for immediate shipping upon receipt of an order. For further information or to place an order, please visit the article webpage.

ElectrophoresisElectrophoresis equipment is used to separate mixtures of protein, DNA or RNA, based on their electric charge, size and other physical characteristics, by passing them through a medium such as a polyacrylamide gel, an agarose gel or a capillary tube. Electrophoresis equipment includes horizontal and vertical gel electrophoresis chambers, isoelectric focusing systems, 2D electrophoresis and capillary electrophoresis instruments. Precast gels with a gradient can be used or gels can be hand cast. Samples are run alongside ladders or markers to identify the approximate size of a molecule. Separated proteins and nucleic acids in the gel can be stained or probed with fluorescent markers and then imaged and detected using gel documentation instruments, transilluminators, densitometers and scanners.

Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.
