Used in biomedical research to quantify levels of glucose-regulated protein 78 (GRP78) in human samples, this ELISA kit is essential for studying cellular stress responses, particularly endoplasmic reticulum (ER) stress. It is widely applied in research on diseases such as diabetes, cancer, neurodegenerative disorders, and viral infections, where GRP78 expression is altered. The kit enables researchers to assess GRP78 as a potential biomarker for disease progression or therapeutic response. Its high sensitivity and specificity make it suitable for use in cell lysates, serum, plasma, and other biological fluids in experimental and preclinical studies.
