Used in immunological and biomedical research to quantify MALT1 protein levels in cell lysates or tissue samples. Helps investigate its role in lymphoma development, autoimmune diseases, and chronic inflammation. Supports studies on NF-κB signaling pathway activation and evaluates the effectiveness of MALT1-targeted inhibitors in preclinical drug development. Commonly applied in cancer research, especially for B-cell lymphomas and MALT lymphoma subtypes.
