ProteoPrep® Reduction and Alkylation Kit

  •  NACRES NA.32




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
