Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Detection of Human alpha ‑L‑Iduronidase/IDUA by Western Blot. Western blot shows lysates of human kidney tissue and IMR-90 human lung fibroblast cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human a-L-Iduronidase/IDUA Monoclonal Antibody (Catalog # MAB4119) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for a-L-Iduronidase/IDUA at approximately 74 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

alpha -L-Iduronidase encoded by the IDUA gene is an important enzyme required for the lysosomal degradation of glycosaminoglycans (GAGs). It hydrolyzes the non‑reducing terminal alpha -L-iduronic acid residues in GAGs including dermatan sulfate and heparan sulfate. Mutations in IDUA that result in enzymatic deficiency lead to the autosomal recessive disease mucopolysaccharidosis type I (MPS I) (1). MPS I causes progressive cellular, tissue and organ damage, and several clinical studies using enzyme replacement therapy have shown promising benefits (2). The sequence of human IDUA shares 79% amino acid identity with mouse IDUA.

We used this antibody for an ELISA in order to detect human Iduronidase as a positive control for our tests. It worked perfectly at a working concentration of 2ug/mL.
