The BEF ELISA kits listed below are analytical tools for measuring concentrations of BEF in various samples. BEF is an alternative name for the human ALYREF gene, which encodes the protein, Aly/REF export factor. It has been mentioned that BEF plays a role in RNA splicing and osteoblast differentiation, among other functions. Structurally, the ALYREF protein is described to be 257 amino acid residues in length and 26.9 kilodaltons in mass. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is reported to be expressed in a wide variety of cancer types. This protein is known to be methylated. Other names for this target antigen include ALY and REF.
