9-cis-Retinal
Based on 1 Customer Validation
9-cis-Retinal is a natural retinoid. Dietary 9-cis-β-carotene generates 9-cis-retinoids via cleavage into 9-cis-retinal. 9-cis Retinal binds to cellular retinol-binding protein-I (CRBP-I) and CRBP-II with Kds of 8 nM and 5 nM, respectively. 9-cis-Retinal expedites differentiation and maturation of rod photoreceptors in retinal organoids.

The addition of 9-cis-Retinal, instead of the widely used all-trans retinoic acid, accelerates rod photoreceptor differentiation in organoid cultures, with higher rhodopsin expression and more mature mitochondrial morphology evident by day. 9-cis-Retinal can bind opsin to form functioning rhodopsin[3].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
