Product Name: Desmin Human

Product No: PRO-520

Synonym(s): Desmin Human Recombinant, Desmin, DES, CSM1, CSM2, CMD1I, FLJ12025, FLJ39719, FLJ41013, FLJ41793.

Description: Desmin Human Recombinant having a calculated molecular mass of 53,539 Dalton, showing a 55kDa band on SDS-page, pI-5.16.

Protein Derived From: Escherichia Coli.

Physical Appearance: Sterile Filtered White lyophilized (freeze-dried) powder.

Purity: Greater than 95.0% as determined by SDS-PAGE.

Stability: Lyophilized Desmin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Desmin 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.

Solubility: It is recommended to reconstitute the lyophilized Desmin in sterile 18MOmega-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Reconstitution to filaments: After Desmin is dissolved in 9.5M urea buffer (see formulation), protofilaments and filament complexes are obtained by dialyzing the resulting polypeptide solution stepwise to a concentration of 4M urea and then to low salt condition (50mM NaCl, 2mM dithiothreitol, 10mM Tris-HCl, pH 7.4). For immunization purposes, the solution can be further dialyzed against PBS (phosphate buffered saline, e.g. Dulbecco's PBS).
