Used in research and diagnostic applications to detect and study BTN1A1 (Butyrophilin Subfamily 1 Member A1), a protein involved in lipid secretion and immune regulation. Plays a key role in understanding mammary gland function and milk fat globule formation. Also utilized in immunoassays, Western blot, flow cytometry, and immunohistochemistry to examine BTN1A1 expression in tissues. Investigated for potential therapeutic applications in autoimmune disorders and cancers due to BTN1A1's role in immune modulation.
