Effect of sample storage conditions on the spectra quality. A Comparison of LSVs obtained following reference TP database query with MS spectra of An. gambiae S fed on human blood, collected 12 h post-feeding and stored from 1 to 8 weeks, at −20 °C (frozen group); in 70 % ethanol at RT (alcohol group) or in a tube containing silicagel at RT (dry group). Dashed line represent the threshold value for relevant identification (LSVs >1.8). LSV, log score value. B Alteration of MALDI-TOF MS profiles from An. gambiae S specimens fed on human blood according to preservation mode. MS profiles from engorged An. gambiae S abdomens stored at −20 °C during 1 (a) or 4 (b) weeks; in 70 % ethanol at RT during 1 (c) or 4 (d) weeks; or in a tube containing silica gel at RT during 1 (e) or 4 (f) weeks. au arbitrary units; m/z mass-to-charge ratio
