Table S3, Mass-to-charge ratios (m/z) of precursors and product ions as well as collision energies (CE) of diagnostic transitions during multiple reaction monitoring of heterocyst glycolipids at Quadrupole 1 (Q1) and 3 (Q3)

Heterocyst glycolipids (HGs) were analyzed using an Agilent 1290 ultra high-performance liquid chromatograph coupled to an Agilent 6410 triple quadrupole mass spectrometer equipped with an electrospray ionization interface operated in positive mode, following Wörmer et al. (2012).
