Purified Mouse Anti-Desmin
Western blot analysis of desmin. Mouse muscle lysate was probed with anti-desmin (clone RD301, Cat. No. 550626) at concentrations 0.25 (lane 1), 0.125 (lane 2), and 0.06 µg/ml (lane 3). Desmin is identified as a band of ~53 kDa.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.

Recommended Assay Procedures

Applications include western blot analysis and immunofluorescence microscopy on frozen sections although IF is not tested at BD Pharmingen. Mouse muscle lysate is recommended as a positive control.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.

Intermediate filaments (IF) are a subset of cytoskeletal proteins which function to give overall structural integrity to the plasma membrane as well as organize cells into specific tissues. IF proteins can be divided into six major types based upon the similarity in sequence. Desmin belongs to the type III category of IF proteins which are predominantly expressed in muscle cells including cardiac, skeletal and smooth muscle. Furthermore, the expression of desmin is regulated in a stage and tissue-specific manner, since it is induced during terminal differentiation of skeletal muscle cells. In skeletal cardiac muscle cells, desmin is localized in the Z-disk region and at the intercalated disk and acts to stabilize sarcomeres in stimulated muscle. Desmin migrates in SDS/PAGE as a 53 kDa protein.

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
