Positive electrospray ionization linear MSn analysis of bone marrow samples. (A) MS1 profile of GSLs isolated from an AML patient bone marrow sample; the expression of Lc3 (1255) was at a high level. (B) MS1 profile of GSLs isolated from a healthy control bone marrow sample; the expression of Lc3 (1255) was at a low level.
