CloneID: CL10
Antigen Long Description: FRβ-transfected RBL2H3 cells.
Buffer Composition: PBS only.
Chimeric Use Statement: This chimeric mouse antibody was made using the variable domain sequences of the original Rat IgG2a format, for improved compatibility with existing reagents, assays and techniques.
Uniprot Accession No.: Q05685
Application Notes (Clone): The antibody binds specifically to FRβ, a member of the folate receptor family. The receptor binds with high affinity to folic acid and folic acid derivatives, and transports 5-methyltetrahydrofolate into the cell. The receptor is expressed on the surface of tumour associated macrophages (TAMs) that promote growth and metastasis of tumours such as gliomas and colon, breast and lung carcinomas. Research has shown FRβ is only expressed on activated macrophages, and thereby a monoclonal antibody that targets the receptor can be useful in the diagnosis of the cancer. Furthermore, the antibody may be conjugated with a toxin, delivering the drug only to TAMs and not to healthy macrophages.
