doi: 10.1158/2326-6066.CIR-21-0874

Figure Lengend Snippet: Assessing mCD69 expression in primary mouse T cells using flow cytometry and [89Zr]-DFO-H1.2F3 uptake. A, Scheme of CD69 antibody binding: H1.2F3 monoclonal anti-CD69 binds to mCD69 on the surface of activated primary mouse T cells and other immune cells. B, Scheme of CD69 imaging: CD69 can be used as a biomarker to distinguish immunologically active tumors of mice that respond to checkpoint blockade (CBP) therapy (responders) from the tumors of mice that do not respond to therapy (nonresponders). C, Ex vivo flow cytometry analysis of CD69 expression for primary mouse T cells treated with PMA/ionomycin or untreated primary mouse T cells. D, Ex vivo [89Zr]-DFO-H1.2F3 uptake for primary mouse T cells treated with 50 ng/mL PMA and 1 μg/mL ionomycin, untreated primary mouse T cells, and CT26 cells. Uptake was measured on γ-counter and normalized to percent injected dose per million cells (% ID/106 cells). Error bars, SD.

Article Snippet: To probe for CD69, a polyclonal rabbit anti-murine CD69 was used (1:50; 1 mg/mL; Bioss, catalog no. bs-2499R) followed by a goat anti-rabbit IgG amplifier Ab and an horseradish peroxidase (HRP)-conjugated horse anti-goat Ab (ImmPRESS Excel Amplified Polymer Staining Kit, Vector Laboratories, catalog no. MP-7451-15).
