特異性:This item is specific for morphine and exhibits negligible cross-reactivity with codeine. This antibody is suitable for use in polarisation fluoroimmunoassays using normorphine-N-hemisuccinate conjugated to FTC-ED as a tracer. Morphine is a potent opiate analgesic drug that acts on the opioid receptors to regulate stress perception, pain control, reward behavior, and neurohormone secretion in reward-relevant brain systems.
