Immunohistochemistry Selection Guide
Follow the simple steps below to choose the most appropriate immunohistochemistry (IHC) reagents for your experiment.

Choose Primary Antibody
• Specific for antigen of interest
• Consider tissue species and preparation (fixation)
• Consider antigen retrieval requirements
Blocking Reagents
• Choices determined by the options selected in Steps 1-4
• BLOXALL® Endogenous HRP and AP Blocking Solution
• Avidin/Biotin Blocking Kit (if using VECTASTAIN® ABC system)
• Normal Sera (from the species of secondary antibody)
• M.O.M.® Mouse Ig Blocking Reagent
• Animal-Free Blocker® and Diluent
• BSA
• Casein Solution
SECONDARY DETECTION SYSTEMS

Choose Secondary Antibody and Tertiary Detection System
• Choose HRP or AP enzyme system
• Consider sensitivity requirements of immunohistochemistry reagents
• Consider species of primary antibody
• Consider tissue species
