Responses of female C57BL/6 to BC and BB male urine with different levels of recombinant darcin added. In each test, mice were presented with two urine samples from BB (white bars), BC (diagonal hatched bars). Values before BB refer to the concentration of recombinant darcin added (μg/μL). *Indicates a significant (P < 0.05) difference between the investigation times in each trial. The data are presented as mean ± SE, n = 12 in each group. BB: BALB/c strain; BC: hybrid of BALB♀ × C57♂.
