This technology includes a generated polyclonal antibody in rabbit that detects the mitochondrial uniporter (MCU) protein. This antibody was created by immunizing rabbits with a synthesized sequence of the MCU protein and can be used to identify and quantify MCU protein in various tissues. The polyclonal nature of the antibody ensures it recognizes multiple epitopes on the MCU, enhancing detection reliability. This technology is crucial for understanding MCU's role in mitochondrial function and mammalian physiology.
