Chemical Properties
| Description | Ponceau 4R (Acid Red 18) is a synthetic strawberry red azo dye that is a food colorant dye used in a variety of food products. It is stable to light, heat and acid, but fades in the presence of ascorbic acid. It is usually synthesized from aromatic hydrocarbons. |
| In vitro | Tissue Staining: 1. prepare a staining solution for Ponceau 4R (usually in water or an appropriate buffer at a concentration of 0.1%-1%). 2. for staining of tissue sections or certain biological samples, after which the stain is rinsed with an appropriate solution to remove background staining. 3. protein electrophoresis or immunoblotting experiments: under certain circumstances, Ponceau 4R may be used as a dye to detect protein bands, but is less commonly used for routine immunoblotting (WB) because its azo dye properties may interfere with certain experimental analyses." |

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% Saline/PBS/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 μLSaline/PBS/ddH2O 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 μLSaline/PBS/ddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
