Field of Research
Cell Biology
Purity
Greater than 95.0% as determined by SDS-PAGE.
Form
Sterile Filtered White lyophilized (freeze-dried) powder.
Solubility
It is recommended to reconstitute the lyophilized KRT20 in sterile 18MΩ-cm H2O not less than 100μg/ml, which can then be further diluted to other aqueous solutions.
Storage Conditions
Stability: Lyophilized KRT20 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution KRT20 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please prevent freeze-thaw cycles
Notes
For research use only.
Applications Notes
Reconstitution to filaments: Performed by mixing equimolar amounts of cytokeratins of type I and type II at concentrations of approx. 0.5 mg/ml, 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 NaCI, 2 mM dithiothreitol, 10 mM Tris-HCI, pH 7.4) . For immunization purposes, the solution can be further dialyzed against PBS (phosphate buffered saline, e.g. Dulbecco's PBS)
Preservative
The protein (1mg/1ml) was lyophilized after from a sterile solution containing 30mM Tris-HCL pH-8, 9.5M urea, 2mM DDT, 2mM EDTA and 10mM methylammonium chloride.
