Chunxia,

The antibody has not been shown to work on formalin-fixed paraffin embedded tissue (check the spec sheet).
My previous experience with dystroglycans and most other muscular dystrophy markers (Novocastra has the best antibodies for this type of work) is that they only work on frozen sections

  Hello, everyone! I stained frozen and paraffin-embedded sections of human skeleton and kidney tissues using the Anti-α-Dystroglycan antibody, clone VIA4-1(catalog #: 05-298) from Upstate biotechnology company by immunohistochemistry. The method is: 3um sections, EDTA 8.0 heat retrieval(pressure cooking) 10min for paraffin section，antibody dilution is 1:50,1:100 and 1:200(25 degree, 2 hours), and addition of EnVision antibody complex, and then DAB. But there was no any positive signals. 
   I do not know what is the matter. Please help me. Now, I need to know whether the dilution or reaction time is suitable. Please give me some good suggestions. I am eager to using the antibody smoothly. Thank you very much.
Sincerely,
