Used in biomedical research to quantitatively measure Human Ring Finger Domain Protein 1 (CGRRF1) levels in cell lysates, tissue extracts, and biological fluids such as serum or plasma. The kit enables researchers to study the protein's role in cellular processes including ubiquitination, protein degradation, and potential involvement in cancer progression or neurodegenerative diseases. It is widely applied in molecular biology and pathology labs for biomarker validation, drug development studies, and functional genomics research. The assay provides high sensitivity and specificity, allowing detection of low-abundance CGRRF1 in small sample volumes, making it suitable for longitudinal studies and high-throughput screening.
