Application :  Protein standard in 1D and 2D SDS- gel electrophoresis


                       Antigen for immunisation

Purity >95% determ. by SDS-PAGE

Isoelectric point pH I: 5.66

Reconstitution (100ug) 70ul DI water (final volume 100ul)

                       (250ug) 175ul DI water(final volume 250ul)

Final solution contains: contain 30mM Tris/HCl pH 8, 9.5M urea, 2mM EDTA, 2mm DTT, 10mM methyamonium chloride,with a protein conc. of 1mg/ml

Special Conditions:

-For immunization purposes, the solution can be further   dialyzed against PBS).

-reconstitution to filaments is performed by mixing equimolar amounts of   cytokeratins of Type 1 and type II at concentrations of approx 0.5mg/ml,   both dissolved in 9.5M urea buffer (as per above formulation)   Protofilaments and filament complexes are obtainined by dialyzing   the resulting polypeptide stepwise to a concentration of 4M urea and   then to low salt concentration (50mM NaCl, 2mM dithiothreitol, 10 mM Tris-HCL, pH 7.4).
