GLUT5/SLC2A5 Blocking Peptide (#BLP-GT025) is the original antigen used for immunization during Anti-GLUT5 (SLC2A5) Antibody (#AGT-025) generation. The blocking peptide binds and ‘blocks’ Anti-GLUT5/SLC2A5 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.
