Immunohistochemistry Technical Support

CST is committed to supporting the diverse needs of the research community. Our team has worked diligently to offer over 700 recombinant monoclonal antibodies, rigorously validated for immunohistochemistry (IHC) using FFPE tissues. This allows our scientists to provide expert advice that will save you time and accelerate your results. Our extensive validation ensures that all of our IHC-P validated antibodies can be used for fluorescent multiplex IHC.

Contact our advanced technical support team to answer questions with your assay, including detailed information on:

  • IHC validation
  • IHC assay troubleshooting
  • Leica® Bond autostainer protocol development
  • Multiplex IHC assay protocols and troubleshooting
