OST4 ELISA kits are immunoassay tools for the measurement of the protein oligosaccharyltransferase complex subunit 4, non-catalytic, which is encoded by the OST4 gene in humans. Functionally, this protein is a known subunit of the oligosaccharyl transferase (OST) complex that catalyzes the initial transfer of a defined glycan (Glc(3)Man(9)GlcNAc(2) in eukaryotes) from the lipid carrier dolichol-pyrophosphate to an asparagine residue within an Asn-X-Ser/Thr consensus motif in nascent polypeptide chains, the first step in protein N-glycosylation. The canonical protein structure is reported to have an amino acid length of 37 residues, a mass of 4.2 kDa, and is a member of the OST4 protein family. It is known to be localized in the ER. Other alias names for this target include oligosaccharyltransferase 4 homolog, and dolichyl-diphosphooligosaccharide--protein glycosyltransferase subunit 4.
There are OST4 ELISA kits that can detect a target at concentrations as low as 0.156 ng/mL and as high as 10 ng/mL. Click on the products below for more detailed ELISA kit information, such as target reactivity and assay sensitivity.
