Descrição-alvo

Arylsulfatase A (UniProt: P15289; also known as EC:3.1.6.8, ASA, ARSA, Cerebroside-sulfatase) is encoded by the ARSA gene (Gene ID: 410) in human. Arylsulfatases are shown to occur in various tissues and fluids and are classified into A, B and C enzymes. Of these, the B and C enzymes act to desulfate sulfated glycosaminoglycans and steroid sulfates, respectively. Arylsulfatase A that is detected in endoplasmic reticulum (ER) and in lysosomes catalyzes the desulfation of 3-O-sulfogalactosyl residues in glycosphingolipids. The conversion to 3-oxoalanine of a serine or cysteine residue in prokaryotes and of a cysteine residue in eukaryotes, is reported to be critical for catalytic activity. Its enzymatic activity requires the presence of saposin B as an activator. Arylsulfatase A activity is inhibited by phosphate groups that form a covalent bond with the active site 3-oxoalanine. It is synthesized with a signal peptide (aa 1-18), which is subsequently cleaved off to produce the mature form that can exist as a homodimer at neutral pH or as a homooctamer at acidic pH. Mutations in ARSA gene are known to cause metachromatic leukodystrophy (MLD), an autosomal recessive disease caused by abnormal intra-lysosomal accumulation of cerebroside-3-sulfate in central and peripheral nervous systems and other organs. It is characterized by leukodystrophy, progressive demyelination and a variety of neurological symptoms, including gait disturbances, ataxias, optical atrophy, dementia, seizures, and spastic tetraparesis. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

forma física

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstituição

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Armazenamento e estabilidade

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
