- 10 mM Tris-HCl (2)
- 2 mM dithiothreitol (2)

Protein standard in 1D and 2D SDS gelelectrophoresis.
Immunoassays.
Immunization.
Protocol: Reconstitution to filaments is performed by mixing equimolar amounts of keratins of type I and type II at concentrations of approx. 0.5 mg/ml (2) - both dissolved in 9.5 M urea buffer (see above). Protofilaments and filament complexes are obtained by dialyzing the resulting polypeptide solution stepwise to a concentration of 4 M urea and then to low salt condition (50 mM NaCl (2)
- e.g. Dulbeccos PBS). (2)
-
pH 7.4).
For immunization purposes (2) - the solution can be further dialyzed against PBS (phosphate buffered saline (2)
