Anti-WRN Antibody, clone 20A11.1 ZooMAb^® Mouse Monoclonal

Bifunctional 3′-5′ exonuclease/ATP-dependent helicase WRN (UniProt: Q14191; also known as DNA helicase RecQ-like type 3, RecQ protein-like 2, Werner syndrome protein) is encoded by the WRN (also known as RECQ3, RECQL2) gene (Gene ID: 7486) in human. WRN is a multifunctional, monomeric, enzyme that exhibits both magnesium and ATP-dependent DNA-helicase activity and 3′->5′ exonuclease activity towards double-stranded DNA with a 5′-overhang. It can also form homooligomers. It plays a role in repair of double-strand DNA following -irradiation. It does not have any nuclease activity towards single-stranded DNA or blunt-ended double-stranded DNA. It binds preferentially to DNA substrates containing alternate secondary structures, such as replication forks and Holliday junctions. It may also play a role in the dissociation of joint DNA molecules that can arise as products of homologous recombination, at stalled replication forks or during DNA repair and alleviates stalling of DNA polymerases at the site of DNA lesions. Mutations in WRN gene have been linked to development of colorectal cancers and Werner syndrome that is characterized by the premature onset of multiple age-related disorders. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Clone 20A11.1 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects Werner′s syndrome protein (WRN).

Purified recombinant mouse 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.

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
