  the reported case. Routinely, blood collection is performed on day 2 on the
  non-anesthetized animal.

case_images: Three and 7 days later (i.e., on days 5 and 9 post PGF2 administration) additional blood samples were collected for progesterone monitoring with the animal being awake and non-sedated (Fig. 2).
case_images: Cross-reactivity determination of alfaxalone
  measurement in the progesterone enzyme immunoassay used for analysis of
  serum progesterone concentrations of common marmosets. Concentration values
  at 50 % binding (50 % B0) for progesterone and alfaxalone used for
  calculation of the alfaxalone cross-reactivity data are indicated.

case_images: Moreover, the assay produces biologically valid results by demonstrating the reliable discrimination of ovarian cycle stages in the marmoset, with progesterone concentrations  10 and  10 ng mL indicating the follicular and luteal phase of the ovarian cycle, respectively (Harlow et al., 1983) (see Fig. 3 as example).
