Fc receptors (FcRs) are glycoproteins of approximate molecular weights of 50-70 kD. They’re broadly expressed
all through the immune cells. Fc receptors are current on leukocytes resembling monocytes, tissue macrophages, B cells,
granulocytes (eosinophils, basophils, neutrophils), NK cells and a few T cells. Fc receptors are additionally current on mast cells, follicular dendritic cells, epithelial cells, endothelial cells, hepatocytes and langerhans cells amongst others. There are a number of sorts of Fc receptors (FcR) that are categorised based mostly on the antibody that they acknowledge. There are people who have nice affinity for the Fc area of monomeric IgG antibody and are known as Fc-Gamma receptors, people who bind to IgA antibody are known as Fc-alpha receptors and people who bind IgE antibody are known as Fc-epsilon receptors.
Non particular Fc receptors staining in assays resembling IHC, ICC, Immunofluorescence (IF) and circulation cytometry may result from the binding of the Fc area of the first and/or secondary antibody or immunoglobulin isotypes to the Fc receptors of the cells. Eliminating Fc receptor staining is fascinating in IHC, ICC, IF and Circulation cytometry assays for the aim of correct knowledge analysis.
For IHC, ICC, IF testing: The binding of the Fc area of main and/or secondary antibody and immunoglobulin
isotypes to the Fc receptors current on cells/tissues give rise to non-specific Fc receptor staining. Specimens wealthy in Fc receptors embody spleen, lymphoid tissues, lymphomas, tonsil, lymph nodes, bone marrow, blood smears and liver. Others embody tissues and cell preps meant for staining for CD markers; Immunoglobulins (Igs), Kappa and Lambda and tumor cell strains that categorical Fc receptors. To keep away from Fc receptor staining; tissue sections and cell preparations are incubated with Innovex Fc Blocker for a brief interval previous to utility of main antibody or immunoglobulin isotypes (See instruction part of this knowledge sheet).
For Circulation cytometry assays: Fc receptors are current on leukocytes (white blood cells), many cell strains in addition to different
cell sorts in each human and animal cells/tissues. Fc receptors offers rise to non-specific Fc receptor-staining in circulation
cytometry assays by binding of Fc area of antibodies and isotype controls to Fc receptors of the cells. Non-specific Fc receptors staining will be eradicated by incubating cells with INNOVEX Fc Receptor Blocker for quite a lot of Circulation cytometry assays resembling CD phenotyping, leukemia typing and cell line research. (See instruction part of this knowledge sheet).
PRODUCT DESCRIPTION
Innovex Fc Receptor Blocker is a UNIVERSAL Fc Blocker relevant to blocking all sorts of Fc receptors resembling Fc-gamma receptors of sort I,II and III; Fc -epsilon receptors sort I and II; Fc –alpha receptors, Fcα/ µR and FcRn. Innovex Fc Blocker does NOT comprise antibodies, Immunoglobulins or immunoglobulin fragments. INNOVEX Fc Blocker will be universally utilized to dam all sorts of Fc receptors in all-species together with human, mouse and all-animals This Common Fc Block can be utilized in quite a lot of Immunoassays resembling IHC, ICC, Immunofluorescence and Circulation cytometry. INNOVEX UNIVERSAL Fc BLOCK is appropriate for blocking Fc receptors in frozen and paraffin tissuesections and cyto preps of human and all-animal species. INNOVEX Fc Blocker can also be generally used for eliminating background staining in mind cells/tissues.
