The ProteoPrep Reduction & Alkylation Kit contains the necessary reagents to conveniently reduce and alkylate disulfide binds in preparation for 2D gel electrophoresis. These reagents are compatible with chaotropic extraction reagents and are conveneintly packaged to save time and increase efficiency. The kit contains five vials of both the reducing agent, tributylphosphine (TBP), and the alkylating agent, iodoacetamide.

Features and Benefits

  • Tributylphosphine is supplied safely as a 200 mM solution in N-methyl-2-pyrrolidine
  • Reduction and alkylation of protein samples increase 2D spot resolution
  • Conveniently packaged components save time and increase efficiency
  • Compatibility with chaotropic extraction reagents simplifies sample preparation

The field of proteomics is continually looking for new ways to investigate protein dynamics within complex biological samples. Recently, many researchers have begun to use RNA interference (RNAi) as a method of manipulating protein levels within their samples, but the ability to accurately determine these protein amounts remains a challenge. Fortunately, over the past decade, the field of proteomics has witnessed significant advances in the area of mass spectrometry. These advances, both in instrumentation and methodology, are providing researchers with sensitive assays for both identification and quantification of proteins within complex samples. This discussion will highlight some of these methodologies, namely the use of Multiple Reaction Monitoring (MRM) and Protein-AQUA.
