| Description | X-NeuNAc (5-Bromo-4-chloro-3-indolyl-alpha-D-N-acetylneuraminic acid sodium salt) is a new chromogenic assay substrate of neuraminidase activity in bacterial expression systems. |
| In vitro | X-Neu5Ac was hydrolyzed by neuraminidase to release a halogenated product undergoing rapid aerobic oxidation to form the dark blue pigment. Preliminary kinetic studies indicated that X-Neu5Ac was a good and stable substrate for neuraminidase. In addition, X-Neu5Ac would also be hydrolyzed mutant enzymes |
| In vivo | To visualize extracellular sialidase activity on the membrane surface in the rat brain, acute brain slices were incubated with X-NeuNAc at pH 7.3. After 1h, myelin-abundant regions showed intense fluorescence in the rat brain. Although the hippocampus showed weak fluorescence in the brain, mossy fiber terminals in the hippocampus showed relatively intense fluorescence. In addition, the fluorescence intensities caused by X-NeuNAc was correlated with the sialidase activity. Therefore, staining with X-NeuNAc was specific for sialidase and useful for quantitative analysis of sialidase activities [1]. |

Calculator
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:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
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 DMSO (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.
(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 DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
