Raw data on urine proteomics in buffaloes

These data are related to a study aimed to compare urine proteomics from non- and pregnant buffaloes in order to identify potential biomarkers of early pregnancy. Forty-four females were submitted to a hormonal estrus synchronization and randomly divided into two groups: pregnant (n = 30) and non-pregnant (n = 14). The pregnant group was artificially inseminated and divided into two groups: P12 (n = 15) and P18 (n = 15), in which embryo and uterine fluid samples were collected 12 and 18 days after the insemination during slaughter. The non-pregnant group was also redivided into two groups at the synchronization end: NP12 (n = 7) and NP18 (n = 7). The urine samples were processed for proteomic analysis. Samples were prepared for proteomics (ESI Q-TOF MS/MS).
