TABLE 2.
Quantitative changes in the abundance of proteins identified in uterine luminal fluid (ULF) from pregnant heifers only and produced by in vivo derived Day 16 conceptuses following short-term culture in vitro.*
*
Quantitative differences (average intensities of isobaric tags for relative and absolute quantification (iTRAQ) labels ± SEM) in protein abundance were measured in the ULF of heifers confirmed pregnant on Days 10, 13, 16, and 19 of pregnancy by iTRAQ analysis (n = 4 per time point). Quantitative changes in interferon tau (IFNT) detected in the ULF of confirmed pregnant heifers are also included. ND = not detected.
a,b,c,d
Significant differences in abundance are noted by different superscripts when P < 0.05.
