    FAQs for Complement Factor B (2)

    1. In the immunohistochemistry paraffin section protocol....the PBS buffer....should it be at certain pH?
      • For IHC application, different labs cites the pH of PBS buffer in the range of 7.1 - 7.6 but most commonly used pH is pH 7.4 (this is what we use in our lab). You may use this PBS (pH 7.4) for making permeablization buffer, antibody diluent buffers and for making wash buffer. For more on the protocol that we use in our lab and for IHC-P troubleshooting suggestions, you may visit: IHC-P Protocol and IHC-P Troubleshooting.
    2. I was wondering what does Format 7C mean as far as anitbodies go?
      • 7C is a fluorophore - it is useful for FLOW. The details of the fluor are (A=425, E=500)
