    FAQs for xCT (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)

A 42 kDa band was identified in lysates from retinas of all species.Immunohistochemistry: Glutamine Synthetase Antibody [NB110-41404] - Localization of glutamine synthase in the retina. Paraffin sections of mouse (A, B), rat (C, D, G-I), or human (E, F) retina fixed in 4% paraformaldehyde were reacted with anti-glutamine synthase (red fluorescence staining in B, D, G, I, and brown immuno-peroxidase reaction [using ABC kit and visualization with DAB product in F]. Nuclei in some immunofluorescence experiments (A-D) were stained with DAPI (shown in cyan), and with nuclear fast red in E and F.  On inspection at low magnification, anti- glutamine synthase reacted with a single population of cells extending from the ganglion cell layer (GCL) through the inner nuclear layer (INL). No signal was detected in controls either pre-incubated with 100ug/ml of the immunizing peptide (A) or with pre-immune serum (C, E). The pattern of staining observed in all experiments is typicals. This finding was confirmed by co-localization (indicated by yellow in I) of glutamine synthase (red in G) with antoher marker of glutamine synthase (green in H).
