| Storage and Stability: | 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. |
| Target description: | Probable ATP-dependent RNA helicase DHX37 (UniProt: Q8IY37; also known as EC:3.6.4.13, DEAH box protein 37) is encoded by the DHX37 (also known as DDX37, KIAA1517) gene (Gene ID: 57647) in human. DHX37, a member of the DEAD box helicase family, is an ATP-binding RNA helicase that plays a role in maturation of the small ribosomal subunit in ribosome biogenesis. It is required for the release of the U3 snoRNP from pre-ribosomal particles. Lack of DHX37 is reported to trigger a surveillance pathway that leads to degradation of pre-ribosomal particles and a depletion of DHX37 is shown to inhibit the conversion of the 21S pre-rRNA to 18SE. Its expression has been reported in fallopian tube, ovary, uterus, and testis and is also detected in the brain. Its DEAH box motif is localized to amino acids 372-375. It plays a role in early testis development and its pathogenic variants are reported to cause 46,XY gonadal dysgenesis and lead to testicular regression syndrome. Mutations in DHX37 gene are also reported to cause neurodevelopmental disorders with brain anomalies that are characterized by severe developmental delays, cortical volume loss and cerebellar hypoplasia. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
