Spleen tyrosine kinase is a cytoplasmic non receptor tyrosine kinase that mediates signaling downstream of immunoreceptors such as the B cell receptor, Fc receptors, and integrins. Phosphorylation at tyrosine 323 is a critical modification that regulates kinase activity and adaptor interactions. Phospho-Syk (Tyr323) antibody provides a selective tool for studying immune signaling, B cell activation, and inflammatory responses.\u003cbr\u003e\u003cbr\u003eSpleen tyrosine kinase is activated when immunoreceptors are crosslinked, leading to phosphorylation of ITAM motifs and recruitment of SYK through its tandem SH2 domains. Once engaged, SYK becomes phosphorylated at multiple sites, including tyrosine 323, which enhances its catalytic activity and binding to signaling partners. Research with Phospho-Syk (Tyr323) antibody has demonstrated that this phosphorylation event promotes propagation of signaling cascades leading to calcium flux, MAP kinase activation, and transcriptional responses. These events are fundamental for lymphocyte activation and immune defense.\u003cbr\u003e\u003cbr\u003eBeyond lymphocytes, SYK plays roles in innate immune cells, including macrophages, mast cells, and neutrophils. Studies with Phospho-Syk (Tyr323) antibody have shown that phosphorylation at this site regulates Fc receptor signaling, phagocytosis, and cytokine release. Dysregulation of SYK phosphorylation has been linked to autoimmune disease, allergy, and chronic inflammation, making it a therapeutic target. Inhibitors of SYK are in clinical development for treatment of rheumatoid arthritis, lupus, and hematologic malignancies.\u003cbr\u003e\u003cbr\u003ePhosphorylation at tyrosine 323 also contributes to oncogenic signaling. Research with Phospho-Syk (Tyr323) antibody has revealed aberrant activation in leukemias and lymphomas, where it drives proliferation and survival. Monitoring phosphorylation state is therefore critical for understanding pathogenesis and evaluating targeted therapies. Because SYK functions at the intersection of immunity and cancer, its phosphorylation events remain of high biomedical importance.\u003cbr\u003e\u003cbr\u003ePhospho-Syk (Tyr323) antibody is used in western blotting, immunohistochemistry, and flow cytometry. Western blotting distinguishes phosphorylated and unphosphorylated forms, immunohistochemistry localizes activated kinase in tissue samples, and flow cytometry quantifies phosphorylation dynamics in immune cells. These approaches make Phospho-Syk (Tyr323) antibody essential for dissecting immune receptor signaling.\u003cbr\u003e\u003cbr\u003eBy supplying validated Phospho-Syk (Tyr323) antibody reagents, NSJ Bioreagents supports research into immune signaling, autoimmunity, and cancer. Detection of Spleen tyrosine kinase phosphorylation at tyrosine 323 provides a precise measure of immune activation.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ul","offer_id":51552332874008,"sku":"FY13093","price":449.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/danabiosci.com\/products\/nsj-fy13093-100ul","provider":"Dana Bioscience","version":"1.0","type":"link"}
