FKBP51 was detected in immersion fixed paraffin-embedded sections of human prostate using 15 µg/mL Human/Mouse/Rat FKBP51 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4094) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue).

Detection of Human/Mouse/Rat FKBP51 by Western Blot.
Western blot shows lysates of DU145 human prostate carcinoma cell line. PVDF membrane was probed with 0.3 µg/mL of Human/Mouse/Rat FKBP51 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4094) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for FKBP51 at approximately 51 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
Simple Western lane view shows lysates of DU145 human prostate carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for FKBP51 at approximately 61 kDa (as indicated) using 3 µg/mL of Goat Anti-Human/Mouse/Rat FKBP51 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4094) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

FK506 binding protein, 51 kDa molecular weight (FKBP51) is a peptidyl-prolyl isomerase that catalyzes the transition between cis- and trans- proline residues critical for proper folding of proteins. The macrolide immunosuppressants FK506 and Rapamycin are FKBP51 inhibitors. FKBP51 levels are induced by glucocorticoids. It associates with HSP90 complexes that are critical for the proper folding of steroid receptors. Single nucleotide polymorphisms in FKBP51 have been associated with major depression and hyper-responsiveness to antidepressants.
