KCNK13/THIK-1 (extracellular) Blocking Peptide (#BLP-PC121) is the original antigen used for immunization during Anti-KCNK13 (THIK-1) (extracellular) Antibody (#APC-121) generation. The blocking peptide binds and ‘blocks’ Anti-KCNK13/THIK-1 (extracellular) primary antibody, this makes it a good negative reagent control to help confirm antibody specificity in western blot and immunohistochemistry applications. This control is also often called a pre-adsorption control.

- Expression of KCNK13 in rat kidneyImmunohistochemical staining in paraffin-embedded sections of rat kidney using Anti-KCNK13 (THIK-1) (extracellular) Antibody (#APC-121), (1:50). Staining (brown color) is specific for renal tubules while both glomeruli (G) and arterial walls are negative (red arrows). Following Tris-EDTA treatment for antigen retrieval, slides were incubated overnight at 4°C. Hematoxylin is used as the counterstain.
- Expression of KCNK13 in mouse substantia nigra.Immunohistochemical staining of perfusion-fixed frozen mouse brain sections with Anti-KCNK13 (THIK-1) (extracellular) Antibody (#APC-121), (1:200), followed by goat anti-rabbit-Alexa-488. A. KCNK13 immunoreactivity (green) appears in neurons (arrows). B. Pre-incubation of the antibody with KCNK13 (THIK-1) (extracellular) Blocking Peptide (#BLP-PC121), suppressed staining. Cell nuclei are stained with DAPI (blue).
