Detects human, mouse, and rat FKBP12.6 in Western blots. In Western blots, approximately 15% cross-reactivity with recombinant human FKBP12 and less than 1% cross-reactivity with recombinant human FKBP13 and FKBP25 is observed.
Polyclonal Goat IgG
E. coli-derived recombinant human FKBP12.6 Met1-Glu108 Accession # P68106
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Human/Mouse/Rat FKBP12.6 by Western Blot. Western blot shows lysates of human cortex, human hippocampus, and mouse brain tissues. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat FKBP12.6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4174) followed by HRP‑conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for FKBP12.6 at approximately 13 kDa (as indicated). This experiment was conducted using Immunoblot Buffer Group 2.
Detection of Human and Mouse FKBP12.6 by Simple WesternTM. Simple Western lane view shows lysates of human brain (cortex) tissue and mouse brain (cortex) tissue, loaded at 0.2 mg/mL. A specific band was detected for FKBP12.6 at approximately 16 kDa (as indicated) using 50 µg/mL of Goat Anti-Human/Mouse/Rat FKBP12.6 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4174) 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, 12.6 kDa molecular weight (FKBP12.6), also called FKBP1B, is a peptidyl-prolyl isomerase that catalyzes the transition between cis- and trans‑ proline residues critical for proper folding of proteins. The immunosuppressant FK506 is a potent inhibitor of FKBP12.6. FKBP12.6 is localized in the sarcoplasmic reticulum associated with the Ryanodyne receptor RYR2. PKA-induced phosphorylation of RYR2 causes FKBP12.6 dissociation. In heart failure, RYR2 is hyperphosphorylated and has low levels of FKBP12.6 bound to it. Male FKBP12.6 knockout mice have cardiac hypertrophy and lethal exercise arrhythmias.
