We used lysates from two different cell lines, a precursor-B acute lymphoblastic leukemia cell line with a somatic form of BTK, RCH-ACV43 (RRID: CVCL_1851), and the adrenocortical carcinoma cell line SW13 also with somatic BTK43 (RRID: CVCL_0542). This evidence concerns the gene BTK and acute lymphoblastic leukemia.
