Project description:The data contain a proteomic analysis of cloacal fluid from 12 females across the reproductive cycle. Letters are used to indicate individuals, while numbers represent reproductive phases (1 - prereceptive, 2 - receptive, 3 - postreceptive). Due to the fact that the genome of the barn swallow is not fully annotated, proteins were mapped to zebra finch (Taeniopygia guttata) genome.
