Ultevursen

(Synonyms: QR-421a)

고객리뷰

Based on 1 Customer Validation

Ultevursen (QR-421a) is a splice-modulating antisense oligonucleotide targeting exon 13 of the USH2A gene, which restores the functional expression of Usherin protein by inducing exon skipping. Ultevursen binds to USH2A pre-mRNA and modulates the splicing process to specifically skip exon 13 carrying the pathogenic mutation c.2299delG, generating an in-frame transcript and a truncated yet functionally normal protein. Ultevursen exhibits concentration-dependent exon skipping activity in human cells and retinal organoid models, and restores Usherin expression and retinal function in zebrafish and gene-edited mouse models. Ultevursen can be used for related research on type 2 Usher syndrome and non-syndromic retinitis pigmentosa.

All DNA/RNA Synthesis Isoforms :

In Vitro

Ultevursen induces concentration-dependent USH2A exon 13 skipping in WERI-Rb1 cells^[1].
Ultevursen induces concentration-dependent USH2A exon 13 skipping in patient-derived iPSC-derived photoreceptor progenitor cells^[1].
Ultevursen (QR-421a) (50 ng; 3 days) delivered as a U7 snRNA skipper induces USH2A exon 13 skipping in stable HEK293T USH2A-eGFP reporter cells, leading to detectable eGFP expression^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Ultevursen (QR-421a) related PMO restored visual function by inducing exon skipping in ush2a-exon13 mutant zebrafish^[2].
Ultevursen associated AAV-U7 dual skipper (1 μL viral vector suspension; intratympanic + utricle microinjection; P1-P2 neonatal Ush2a KO-1/KO-1 mice; 16 weeks in vivo incubation period) achieves robust hair cell transduction and mediates sustained Ush2a exon skipping within mouse inner ear tissue^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
