Used in biomedical research to measure levels of spleen tyrosine kinase (Syk) protein in human spleen samples. Helps in studying immune cell signaling pathways, particularly in B cells and other hematopoietic cells. Supports investigation of autoimmune diseases, inflammation, and cancers like lymphoma where Syk activity is dysregulated. Enables researchers to evaluate the effectiveness of Syk-targeted therapies in experimental models. Commonly used in academic, pharmaceutical, and clinical research settings for protein quantification in cell lysates and tissue extracts.
