Androgen Receptor Antibody Staining Protocol for Immunohistochemistry


Description: Androgen receptor is a member of the superfamily of ligand responsive transcription regulators. The androgen receptor functions in the nucleus where it is believed to act as a transcriptional regulator mediating the action of male sex hormones (androgens). The androgen receptor has wide tissue distribution and can be demonstrated by immunohistochemistry in several tissues eg prostate (Zhuang et al., 1992), skin (Blauer et al., 1991) and oral mucosa.

Additional Information:
Tissue Type: Prostatic tissue from man, rat or mouse.
Fixation: Formalin-fixed paraffin sections, or Zamboni’s-fixed, frozen sections.
Positive Control: Prostatic tissue from man, rat or mouse.
Negative Control: Omit primary antibody, isotype control, absorption control
Blocking: 2-5% normal serum to reduce unspecific background staining; 0.5-3% H2O2 to block endogenous peroxidase activity; avidin/biotin to block endogenous biotin activity if necessary


There is no need to perform antigen retrieval on frozen sections
