These G4S ELISA kits are immunodetection tools for measuring the levels of G4S in biological samples. G4S is an alias of the human ARSB gene, which encodes the protein, arylsulfatase B. Notably, G4S is known to play a role in autophagy pathways and nervous system development, among other functions. The ARSB protein is 533 amino acid residues in length and 59.7 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the lysosomes of the cell. This protein is known to be glycosylated. Other names for this target antigen include ASB.
