9-cis-Retinal

9-cis-Retinal
9-cis-Retinal is a retinoid with Kd of 8 nM and 5 nM for cellular retinol binding protein-I (CRBP-1) and CRBP-II, respectively. 9-cis-Retinal accelerates the differentiation and maturation of rod photoreceptors in retinal organoids, reduces the toxicity of unliganded opsins, and can be used to study congenital stationary night blindness caused by G90D rhodopsin.

Description
9-cis-Retinal is a retinoid with Kd of 8 nM and 5 nM for cellular retinol binding protein-I (CRBP-1) and CRBP-II, respectively. 9-cis-Retinal accelerates the differentiation and maturation of rod photoreceptors in retinal organoids, reduces the toxicity of unliganded opsins, and can be used to study congenital stationary night blindness caused by G90D rhodopsin.
In vitro
b>METHODS: The binding of 9-cis-retinol, 9-cis-retinal, and 9-cis-RA to CRBPI and CRBPII was monitored through fluorescence spectroscopy, and the data were analyzed using nonlinear regression to determine the apparent dissociation constant K'(d) .
RESULTS: CRBPI and CRBPII bind to 9-cis-retinol (K'(d), 11nM and 68nM) and 9-cis-retinal (K'(d), 8nM and 5nM) respectively with high affinity; CRBPI or CRBPII have not been observed yet. Significant binding of CRBPII to 9-cis-RA. [1]
In vivo
b>METHODS: After recording baseline ERG, IRBP-deficient mice were allowed to rest for 12 hours, and 0.375 mg of 9-cis-retinal was injected intraperitoneally. ERG before and after were analyzed to test 11-cis-retinal in cones of IRBP-deficient mice. retinal defects.
RESULTS: 9-cis-retinal treatment significantly increased cone photoreceptor responses; the cones of IRBP-deficient mice were particularly sensitive to exogenous 9-cis-retinal, and the recovery of cone photoreceptor function to WT levels indicated that IRBP deletion had minimal Cone dysfunction in mice is caused by 11-cis-retinal deficiency.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
