Ovulation-inducing factor: a protein component of llama seminal plasma

Table 1 Bioactivity of different molecular mass fractions of llama seminal plasma in female llamas (Experiment 1).

	≥ 30 kDa (n = 9)	10-30 kDa (n = 9)	5-10 kDa (n = 9)	< 5 kDa (n = 9)	WSP (n = 9)	PBS (n = 9)

Whole seminal plasma (WSP, positive control), phosphate buffered saline (PBS, negative control). Values expressed as mean ± SEM; Day 0 = treatment.
* No difference between groups (P = 0.9).
^{a, b}Proportions with different superscripts are different (P < 0.001).
