The 4F2 ELISA kits listed below utilize specific antibodies for the plate-based assay of 4F2 in various samples. 4F2 is another term for the SLC3A2 gene, which encodes the protein, solute carrier family 3 member 2 in humans. It has been reported that 4F2 plays a role in the transport of ions and carbohydrate metabolism and homeostasis, among other functions. Structurally, the SLC3A2 protein is 630 amino acid residues in length and 68 kilodaltons in mass. However, as many as 5 protein isoforms have been identified. It is localized to the lysosomes and cell membrane of the cell. In terms of tissue specificity, it is found to be widely expressed in all tissues tested with highest levels detected in kidney, placenta and testis and weakest level in thymus. This protein is known to be phosphorylated and glycosylated. Other names for this target antigen include 4F2HC and 4T2HC.
