Product Introduction

Bioactivity

Description	D-Galactose is a naturally occurring hexose and a C-4 epimer of glucose. It can combine with glucose to form lactose and is commonly used to establish animal models of aging.
In vitro	Galactose is important for the survival and virulence of bacteria. Galactose is utilized by the Leloir pathway in Escherichia coli. Two anomers of d-galactose are used for different purposes, α-d-galactose as a carbon source and β-d-galactose for induction of UDP-galactose synthesis for biosynthetic glycosylation[1].
In vivo	Chronic D-galactose exposure induces neurodegeneration by enhancing caspase-mediated apoptosis and inhibiting neurogenesis and neuron migration in mice, as well as increasing oxidative damage. Moreover, D-galactose-induced toxicity in mice is a useful model for studying the mechanisms of neurodegeneration and neuroprotective drugs and agents[2]. D-galactose given by oral route leads to cognitive impairments in rats which are accompanied by oxidative damage. Cognitive impairments is observed in the open-field test in the 4th and 6th weeks after d-gal administration, as well as an impairment in spatial memory in the radial maze test after the 6th week of d-gal administration[3].
Synonyms	D-Galactopyranose, D-(+)-Galactose, Alpha-D-galactose
Disease Modeling Protocol	Aging model Modeling Mechanism： D-Galactose catalyzes the production of galactitol via aldose reductase, causing osmotic pressure damage to cells. It also induces increased vascular permeability, abnormal collagen metabolism, and hypogonadotropic endocrine disorders, mimicking the decline in tissue function associated with aging. Related Products： D-Galactose (T0591) Modeling Method： Experimental Subject： Rats, Sprague-Dawley, Male, 180–280 g Dosage and Administration Route： 10%-50% weight percentage D-galactose, Mixed basal diet, Ad libitum feeding Dosing Frequency and Duration Model： Continuous feeding, 3 consecutive weeks Validation： ⁱ²⁵I-albumin vascular permeability (TBIR values in tissues such as the eye and kidney) was significantly increased; collagen solubility in granulation tissue reached 29%-35.8%; plasma galactose increased by 2.5-11.5 times, and testosterone levels decreased; tissue galactitol content was 135 times that of the control group.

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, and a total of 10 animals are to be administered, using a formulation of 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 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 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 and mix thoroughly until a homogeneous solution is obtained.
