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


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
