Table 2. Peptide signal fold change in camel SON extracts at different seasons as measured by MALDI-TOF MS.

Peptide	(M+H)exp	Intensity* Summer	Intensity* Winter	Ratio Summer/Winter
OT	1007.6	0.41±0.06	0.65±0.54	0.6
VP	1084.8	0.59±0.17	1.19±0.49	0.5

*Normalized (to total ion count) mean relative signal intensity for centroid peaks matching masses of vasopressin (AVP), oxytocin (OT) in the camel SON samples from different seasons (winter n = 4, summer n = 3)
