Chemical Properties
| Description | IR 813 tosylate is a near-infrared (NIR) fluorescent dye with excitation and emission wavelengths of 815 nm and 840 nm, respectively, used for visualizing regional lymph nodes in mice [1]. |
| In vitro | IR 813 tosylate, at a concentration of 17.3 μM applied for 2 hours, induces 31.4% hemolysis in red blood cells [1]. The same compound, when used at a 5.9 μM concentration over a period of 24 hours, causes 50% cell death in MRC-5 cells [1]. |
| In vivo | IR 813 tosylate achieves peak fluorescence intensity at four hours post-injection and exhibits quick extravasation, facilitating the visualization of regional lymph nodes in mice [1]. Recommended protocol guidelines suggest personalizing the procedure to meet individual experimental requirements [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% 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.
