PD - L1 signal was visualized by Cy5, compartmentalized and expressed as
the average signal intensity within the assayed component (AQUA score), with scores on a scale of 0 - 255.
S10 show an
average mass spectrum of the OSC - specific ion
signals identified by high resolution and clearly shows the presence of high -
intensity peaks at m / z 78, 79, and 96 corresponding to CH2SO2 +, CH3SO2 +, and CH4SO3 +, respectively, which are characteristic of MSA (42).
