Dystrophin, Rod Domain
Description:
Dystrophin is a member of the spectrin/alpha-actinin family of actin-binding, triple helix rod-containing proteins. It is absent or greatly reduced in individuals with the X-linked recessive Duchenne’s muscular dystrophy disorder, as well as in mice with the mdx (murine muscular dystrophy) mutation.

Applications:
Suitable for use in Western Blot, Immunohistochemistry and EM Gold. Other applications not tested.

Recommended Dilution:
Western Blot: 1:100-1:250
Immunohistochemistry(Fresh frozen, unfixed tissue): Neat 1:20
Not recommended for use on paraffin embedded tissue.
EM Gold: Undiluted 90 minute incubation at 25°C. Light fixation with 2% formaldehyde + 0.001% glutaraldehyde for 1 hour. Use 2.3M sucrose as cryoprotectant.
Optimal dilutions to be determined by the researcher.

Expected Staining Pattern:
Light microscopy: Continuous rim of labeling at the periphery of muscle fibers
Western Blot: Strong double bands at ~400kD and metabolites of lower molecular mass
E.M. Gold: Close to the cytoplasmic face of the plasma membrane.

Positive Control:
Snap frozen normal human or rat striated muscle.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Specificity:
Recognizes mid rod domain of human dystrophin between aa1181-1388. Reacts with skeletal, cardiac and smooth muscle dystrophin. Reacts on blots with the brain isoform. No reactivity with mdx mouse tissue or DMD/BMD patients who have a gene deletion. Does not react with chicken dystrophin. Species Crossreactivity: mouse, rat, rabbit and canine
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
