Fig. 1From: Phosphate, calcium, and vitamin D signaling, transport, and metabolism in the endometria of cyclic ewes Quantification of phosphate, calcium, and 25(OH)D in uterine flushings, endometrial homogenates, and plasma. Phosphate was quantified in uterine flushings (A), plasma (C), and endometrial homogenates (E) using a colorimetric assay. Similarly, calcium was quantified in uterine flushings (B), and endometrial homogenates (F) using a colorimetric assay. 25(OH)D was quantified in plasma (D) and endometrial homogenates (G) by ELISA. Error bars represent SEM. Different letters indicate that means differ from one another (P < 0.05). n = 4–5 per dayBack to article page
