There were 110 S-nitrosated proteins identified with 2 or more unique peptides. Log2 relative expressions for labor and preterm labor (L/PTL Rel Ex) for these 110 proteins are based on area under the curve analysis of all identified peptides using the nonlaboring state as reference. Note synaptopodin-2 was only positively identified in PTL.
