LCK and melanoma: Using flow cytometry to quantify CAR-M-mediated eating as the percentage of CAR-Ms with A375-Lck-mScarlet fragments (Supplemental Fig. 2d), we found that each CAR-MαCSPG4(225.28/SK5/763.74) engulfed Lck-mScarlet melanoma fragments at higher rates than the control CAR-MGFP (Fig. 1d–f).
