This ELISA kit offers lab-based, high-throughput pregnancy testing for bovine serum, ideal for veterinary diagnostic labs or large operations processing many samples per batch rather than testing cow-side. Using a microplate reader gives quantitative, objective results across a full 192-test plate, useful for herds where consistency and documentation across large sample batches matter more than immediate on-farm turnaround. Shelf life 12 months, store at 2-8°C.
