Additional Notes

  1. Validated by Evelyn Kandov (No ORCID)
  2. Evaluated in human tonsil FFPE samples with CD20 (clone L26) and Hoechst (nuclear marker). Antibody labels T cells. Preferred clone and conjugate for FFPE samples.
  3. Antibody labels T cells. Preferred clone and conjugate for FFPE samples. Works beautifully on Cell DIVE imager with IBEX dye inactivation protocol.
  4. Antibody labels cytotoxic T cells in various human FFPE tissues. Great signal in the lung and works well with the Cell DIVE imager and IBEX dye inactivation protocol.
