Product Introduction

Bioactivity

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].
Synonyms	X-Neu5Ac, 5-Bromo-4-chloro-3-indolyl-alpha-D-N-acetylneuraminic acid sodium salt

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments

and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent

10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO TargetMol | reagent to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO TargetMol | reagent stock solution to 400 μL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 μL Tween 80 and mix well until fully clarified.

3) Add 450 μL Saline,PBS or ddH₂O TargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.

This example is provided solely to demonstrate the use of the In Vivo Formulation Calculator and does not constitute a recommended formulation for any specific compound. Please select an appropriate dissolution and formulation strategy based on your experimental model and route of administration.

All co-solvents required for this protocol, includingDMSO, PEG300/PEG400, Tween 80, SBE-β-CD, and Corn oil, are available for purchase on the TargetMol website.
