Used in biomedical research to quantify levels of Tyrosine Kinase 2 (Tyk-2) in human biological samples such as serum, plasma, or cell lysates. This kit enables researchers to study the role of Tyk-2 in signaling pathways related to immune responses and inflammatory diseases. It is particularly useful in investigating conditions like autoimmune disorders (e.g., lupus, rheumatoid arthritis, psoriasis) and cancers where Tyk-2 activity is dysregulated. The assay supports drug development and evaluation of therapeutic agents targeting the JAK-STAT pathway by providing a reliable method to measure changes in Tyk-2 expression or activation in response to treatment.
