Recombinant Human Cytokeratin 14

cat#RDI-PRO62018       $750.00/250ug

cat#RDI-PRO62218        $438.00/100ug

Description                       Recombinant human cytokeratin 14

Molecular Weight:            51,662 (+ methionin)

                                          51,530 (- methionin; calculated from sequence)

Source:                              E. Coli

Purity:                               Greater than 95% (determined by SDS gel electrophoresis and western blot)

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



Reconstitution:                 100ug: When reconstituted with 70ul distilled water (final volume 100ul),

                                         250ug: when reconstituted with 175ul distilled water (final volume 250ul)

                                          concentration of cytokeratin 14 is 1mg/ml in 30mM Tris/HCL pH 8,

                                           9.5M urea, 2mM DTT, 2mM EDTA, 10mM methylammonium chloride

Storage:                              At 2-8 DEG C (lyophilized) Store -20 DEG C after reconstitituion Avoid frequent freeze thaw cycles.

-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, 10mM Tris-HCL, pH 7.4).
