Overview
Type: Synthetic peptide
Form: Lyophilized powder
IQGAP1 Blocking Peptide (#BLP-PZ055) is the original antigen used for immunization during Anti-IQGAP1 Antibody (#APZ-055) generation. The blocking peptide binds and ‘blocks’ Anti-IQGAP1 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

Applications
Demonstration of Pre-adsorption control
Western blot analysis of mouse brain membranes (lanes 1 and 3) and rat brain membranes (lanes 2 and 4):1, 2. Anti-IQGAP1 Antibody (#APZ-055), (1:200).
3, 4. Anti-IQGAP1 Antibody, preincubated with IQGAP1 Blocking Peptide (#BLP-PZ055) (#BLP-PZ055).- Western blot analysis of human Jurkat T-cell leukemia cell line lysate (lanes 1 and 3) and human MCF-7 breast adenocarcinoma cell line lysate (lanes 2 and 4):1, 2. Anti-IQGAP1 Antibody (#APZ-055), (1:200).
3, 4. Anti-IQGAP1 Antibody, preincubated with IQGAP1 Blocking Peptide (#BLP-PZ055) (#BLP-PZ055). 
Expression of IQGAP1 in mouse cerebellumImmunohistochemical staining of perfusion-fixed frozen mouse brain sections with Anti-IQGAP1 Antibody (#APZ-055), (1:200), followed by goat anti-rabbit-AlexaFluor-488. IQGAP1 immunoreactivity appears in Purkinje neurons (horizontal arrows) and their dendrites (vertical arrows). Cell nuclei are stained with DAPI (blue).
