Anti-CD307e antibodies are used in antigen-specific immunodetection in biological samples. The target CD307e is a known alias name of the protein Fc receptor like 5, encoded by the FCRL5 gene in humans. This 977-amino acid residue protein is suspected to be involved in B-cell development and differentiation in peripheral lymphoid organs and may be useful markers of B-cell stages. It is localized to the cell membrane of the cell and features glycosylated post-translational modifications. In terms of tissue expression, it is reported to be expressed in marginal zone B-cells, immunoblasts, tonsillar germinal center centrocytes and in the intraepithelial and interfollicular regions of the tonsil.
