PRODUCT DATA SHEET: CYTOKERATIN NO 19 (human Recombinant)
CAT# RDI-PRO62014 $500.00/250ug
Molecular Weight 44,098 (calculated from sequence)
40,000 (determined by SDS gel electrophoresis)
Source E. Coli
Application Protein standard in 1D and 2D SDS- gel electrophoresis
Antigen for immunisation
Purity >95% determ. by SDS-PAGE
Amount 250ug (lyoph.,salt balanced)
Isoelectric point pH I: 5.2
Reconstitution (250ug) when reconstituted with 175ul H20 bidest,sol. (final vol. 250ul)will contain 30mM Tris/HCl pH 7.6, 8.0M urea, 0.1mM Na EDTA, 2mM DTT,with a protein conc. of 1mg/ml
-For immunization purposes, the solution can be further dialyzed against PBS).
-reconstituion 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 8M 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).
-see J. Cell Biol 101, 1826-1841 and J. Mol.
Storage at 4 Deg.C (lyoph.) -20 DEG C (diluted) Avoid frequent freeze thaw cycles
