Overview
Type: Synthetic peptide
Form: Lyophilized powder
Kv1.3/KCNA3 (extracellular) Blocking Peptide (#BLP-PC101) is the original antigen used for immunization during Anti-KV1.3 (KCNA3) (extracellular) Antibody (#APC-101) generation. The blocking peptide binds and ‘blocks’ Anti-Kv1.3/KCNA3 (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.
Applications: wb, ihc

Western blot analysis of mouse (lanes 1 and 3) and rat (lanes 2 and 4) brain lysates:1,2. Guinea pig Anti-KV1.3 (KCNA3) (extracellular) Antibody (#APC-101-GP), (1:200).
3,4. Guinea pig Anti-KV1.3 (KCNA3) (extracellular) Antibody, preincubated with Kv1.3/KCNA3 (extracellular) Blocking Peptide (#BLP-PC101).
Expression of KV1.3 in mouse cerebellumImmunohistochemical staining of perfusion-fixed frozen mouse brain sections using Guinea pig Anti-KV1.3 (KCNA3) (extracellular) Antibody (#APC-101-GP), (1:100). KV1.3 staining (red) is detected in Bergmann glia outlines (arrow). DAPI is used as the counterstain (blue) .
