ReadyPrep Protein Extraction Kit (Membrane II)

Overview

Fractionation of Proteins by Cellular Location

Differences in 2-D patterns using ReadyPrep signal (A), membrane I (B), and membrane II (C) kits. Mouse liver samples were extracted using the recommended protocols for each kit. Purified protein (~450 µg) was focused on 17 cm pH 3–10 nonlinear ReadyStrip IPG strips and run on 8–16% PROTEAN II precast gels for the second dimension. Overall spot patterns differ for A, B, and C even though all three kits isolate membrane proteins, indicating each kit isolates different types of membrane proteins.

The ReadyPrep protein extraction kit (membrane II) applies sodium carbonate extraction methods (Fujiki et al. 1982, Molloy et al. 2000) to fractionate and isolate membrane proteins.

The ReadyPrep protein extraction kit (membrane II):

  • Isolates complex proteins that contain more than two transmembrane domains or those that are resistant to extraction by the ReadyPrep protein extraction (membrane I) kit
  • Requires ultracentrifugation
  • Includes a strongly chaotropic, IEF-compatible rehydration/sample buffer that contains the detergent ASB-14 to efficiently solubilize proteins

(1982) for the isolation of cellular membrane fractions after carbonate extraction, and the later adaption of the technique by Molloy et al. (2000). Incubation of tissue or cells with the high-pH Membrane Protein Concentrating Reagent strips weakly associated proteins away from membrane fragments. After ultracentrifugation and washing, the membrane pellet is solubilized using an IEF buffer or other buffer. The included 2-D Rehydration/Sample Buffer 1 contains the zwitterionic detergent ASB-14. The kit also contains the reducing agent tributylphosphine (TBP), which is more efficient than dithiothreitol (DTT) for keeping proteins reduced in 2-D PAGE applications.</p> <h2 class="descHeader">Kit Components</h2> <p>For 10 extractions of 100&ndash;200 mg of cells or tissue:</p> <ul> <li>2-D Rehydration/Sample Buffer 1, 2 vials, reconstituted total 10 ml</li> <li>Lysis Buffer, reconstituted 50 ml</li> <li>Membrane Protein Concentrating Reagent, reconstituted 125 ml</li> <li>TBP Reducing Agent, 1 ampoule; 0.6 ml of 200 mM tributylphosphine (TBP) in 1-methyl-2-pyrrolidinone sealed under nitrogen gas</li> <li>Empty vial for TBP storage </li> <li>Instruction manual</li> </ul> <p>Bio-Rad offers a range of ReadyPrep Kits for Fractionation by Cellular Location.
