Used in biomedical research to quantify Human Platelet Affinity Protein 3 (PKP3) levels in biological samples such as serum, plasma, or cell lysates. The kit enables researchers to study PKP3's role in platelet function, cell adhesion, and intracellular signaling processes. It is commonly applied in studies related to cardiovascular diseases, thrombosis, and epithelial integrity. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for both clinical research and drug development settings where monitoring protein expression changes is critical.
