Overview
Type: Synthetic peptide
Form: Lyophilized Powder
AXL (extracellular) Blocking Peptide (#BLP-TR032) is the original antigen used for immunization during Anti-AXL (extracellular) Antibody (#ATR-032) generation. The blocking peptide binds and ‘blocks’ Anti-AXL (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
Demonstration of Pre-adsorption control
Western blot analysis of rat brain lysate (lanes 1 and 4), mouse brain membranes (lanes 2 and 5) and mouse lung lysate (lanes 3 and 6):1-3. Anti-AXL (extracellular) Antibody (#ATR-032), (1:200).
4-6. Anti-AXL (extracellular) Antibody, preincubated with AXL (extracellular) Blocking Peptide (BLP-TR032).
Western blot analysis of human THP-1 monocytic leukemia cell line lysate (lanes 1 and 3) and human SW-403 colon adenocarcinoma cell line lysate (lanes 2 and 4):1-2. Anti-AXL (extracellular) Antibody (#ATR-032), (1:200).
3-4. Anti-AXL (extracellular) Antibody, preincubated with AXL (extracellular) Blocking Peptide (BLP-TR032).
Expression of AXL in rat parietal cortex.Immunohistochemical staining of perfusion-fixed frozen rat brain sections with Anti-AXL (extracellular) Antibody (#ATR-032), (1:300), followed by goat anti-rabbit-AlexaFluor-488. A. AXL immunoreactivity (green) appears in neuron outlines (arrows). B. Pre-incubation of the antibody with AXL (extracellular) Blocking Peptide (BLP-TR032), suppressed staining. Cell nuclei are stained with DAPI (blue).
