Desmin (DES, CMD1I, CSM1, CSM2, FLJ12025, FLJ39719, FLJ41013, FLJ41793, Intermediate Filament Protein)
Description:
Desmin, a protein of 53kD, is an intermediate filament protein of both smooth and striated muscles. Antibody to desmin reacts with striated (skeletal and cardiac) as well as smooth muscle cells. In skeletal and cardiac muscles, the staining is confined to the Z-bands giving a characteristic striated appearance. Anti-desmin antibody is useful in identification of tumors of myogenic origin. It reacts with leiomysarcomas (smooth muscle) as well as rhabdomysarcomas (striated muscle).

Applications:
Suitable for use in Immunohistochemistry (Frozen). Other applications not tested.

Recommended Dilution:
Optimal dilution determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
