Innovex Fc Receptor Block is a peerless technology designed to block Fc Receptors present on all leukocytes (white blood cells), lymphomas, and melanomas. Fc receptors are also expressed on a majority of tumors. Blocking Fc receptors is essential for accurate typing of lymphoid and tumor tissues and cells. Fc receptor staining occurs by the binding of Fc receptors present on cell to the Fc region of the primary and/or secondary antibody. Fc Receptor Block can be used for IHC (frozen and paraffin) flow cytometry, immunoflorescence and in-situ hybridization and for live cell functional assays.

Fc Receptor Blocker is a must for accurate lymphoma and leukemia typing.

ADVANCED and UNIQUE FEATURES:
• 30 minute incubation step at room temperature
• Blocks Fc Receptors in both human and animal cells
• Eliminates false positive staining of white blood cells, lymphoid tissues, cytosmears (blood & bone marrow)
• Insures accurate lymphoma and leukemia typing
• Eliminates negative control staining of lymphomas, lymphoid tissues, and blood and bone marrow smears
• Eliminates false positive staining for Kappa and Lambda staining
• Eliminates false positive staining of Reed Sternberg cells
• A must for CD markers staining in immunohistochemistry, immunofluorescence
• A must for CD phenotyping via flow cytometry
• A must for Immunoglobulins (Igs) staining via immunohistochemistry, flow cytometry and immunofluorescence
• A must for kappa and lambda staining
