Used in biomedical research to quantify glucose kinase (GK) levels in rat tissue samples, particularly in studies related to glucose metabolism and insulin regulation. Commonly applied in diabetes research to assess pancreatic beta-cell function and liver metabolism. Enables researchers to measure changes in GK protein expression under experimental conditions, supporting drug development and metabolic disease modeling. Suitable for use with serum, plasma, and tissue homogenates. Provides a reliable tool for high-throughput screening in preclinical studies.
