Raw data on uterine fluid proteomics in buffaloes

These data are related to a study that aimed to compare the uterine fluid (UF) of pregnant and non-pregnant buffaloes and describe the relationship between embryo and uterus during 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 UF samples were processed for proteomic analysis. Samples were prepared for proteomics (ESI Q-TOF MS/MS).本数据集关联一项研究，该研究旨在比较妊娠与非妊娠水牛的子宫液（uterine fluid, UF），并解析早期妊娠阶段胚胎与子宫之间的相互关系。研究共纳入44头雌性水牛，经激素发情同步化处理后随机分为两组：妊娠组（n=30）与非妊娠组（n=14）。妊娠组接受人工授精后，进一步分为P12（n=15）与P18（n=15）两个亚组，分别于授精后12天、18天屠宰时采集胚胎与子宫液样本。非妊娠组则于同步化处理结束后，同样分为NP12（n=7）与NP18（n=7）两个亚组。所有子宫液样本均开展蛋白质组学分析，样本经制备后采用ESI Q-TOF MS/MS（电喷雾电离四极杆飞行时间串联质谱）进行检测。
