Used in research to study cell adhesion and immune regulation. Helps in understanding protein-protein interactions involving the PTGFRN receptor. Often employed in binding assays and protein purification due to the His tag. Supports development of therapeutic antibodies by serving as an antigen or target protein. Applied in structural studies like crystallography or cryo-EM to determine 3D conformation. Commonly used in ELISA and Western blotting for detection and quantification in biological samples.
