Used in immunological research to quantify levels of SAMHD1 protein in biological samples, particularly in studies related to antiviral immunity and autoimmune diseases. Helps assess the expression and regulation of SAMHD1 in immune cells, especially in the context of HIV-1 restriction and interferon signaling pathways. Commonly applied in virology, oncology, and molecular biology research to understand cellular responses to viral infection and DNA damage. Provides a reliable, sensitive, and specific method for measuring SAMHD1 in cell lysates and tissue extracts without the need for radioactive labeling.
