Topic:Immunoassay
Immunoassays are analytical techniques used to detect and quantify specific proteins, hormones, or other molecules in biological samples from horses. These assays rely on the specificity of antibodies to bind to target antigens, allowing for the measurement of various substances that can indicate health status or disease. In equine research, immunoassays are employed to assess biomarkers related to metabolic, infectious, and inflammatory conditions. Common applications include measuring hormone levels, detecting infectious agents, and monitoring immune responses. This page compiles peer-reviewed research studies and scholarly articles that explore the development, application, and validation of immunoassays in the context of equine health.
Levels of LH, prolactin and oestrogens in the serum of post-partum mares. The levels of LH, prolactin and oestrogen were measured by radioimmunoassay in serum obtained from six mares during the post-partum period, and LH was also assayed in blood samples collected at 6-hr intervals from four normal cyclic mares during oestrus and at daily intervals during dioestrus. The concentrations of oestrogen and LH suggested that the mares were having ovulatory cycles during the post-partum period irrespective of behavioural oestrus, and the levels of prolactin seemed to rise in association with probable ovulatory LH peaks. In these mares levels of LH had increased significant...
Periovulatory changes in peripheral plasma progesterone and estrogen concentrations in the mare. Concentrations of progesterone and estrogen were measured in peripheral blood plasma samples from mares around the time of ovulation. Samples were collected every 2 hours from 36 hours before, to 26 hours after, ovulation and assayed by radioimmunoassay. Progesterone concentrations were between 60 and 100 pg/ml for the period 24 hours before ovulation through 8 hours after ovulation. By 10 hours after ovulation, concentrations increased to 140 pg/ml and, by 26 hours after ovulation, reached 346 pg/ml. Plasma estrogen concentrations did not change significantly throughout the same period.
