Anti-lineage panel cocktail (TER-119, RB6–8C5, RA3–6B2, M1/70, 145–2C11 at 1:50 dilution) was from BD Biosciences (559971). Unless otherwise specified, all antibodies were used at a 1:100 dilution. All antibodies were anti-mouse and their specificity was validated in previous studies performed in our laboratory3 (link),8 (link),12 (link),27 (link)–29 (link).
