Used in immunological research to quantify granule calcin (Grancalcin) levels in biological samples such as cell lysates, serum, or plasma. Commonly applied in studies related to inflammation, immune cell activation, and autoimmune diseases. Enables researchers to assess Grancalcin expression in neutrophils, monocytes, and macrophages, supporting investigations into cellular differentiation and inflammatory responses. Suitable for both basic research and preclinical studies where precise measurement of this calcium-binding protein is required.
