Nuclear Fast Red

🥰Excellent
Catalog No. T87045Cas No. 6409-77-4
Alias Kernechtrot

Nuclear Fast Red is an anthraquinone dye that serves as a red nuclear counterstain when aluminum ions are present in excess, thereby aiding in histological visualization of nuclear components. Nuclear Fast Red additionally functions as a histochemical and colorimetric reagent for calcium detection,Nuclear Fast Red further acts as a highly sensitive “off/on” fluorescent probe for the detection of guanine, making it a multifunctional research reagent.

Description
Nuclear Fast Red is an anthraquinone dye that serves as a red nuclear counterstain when aluminum ions are present in excess, thereby aiding in histological visualization of nuclear components. Nuclear Fast Red additionally functions as a histochemical and colorimetric reagent for calcium detection,Nuclear Fast Red further acts as a highly sensitive “off/on” fluorescent probe for the detection of guanine, making it a multifunctional research reagent.
In vitro
Nuclear Fast Red possesses both photosensitive properties and DNA affinity: under visible light excitation, it generates reactive oxygen species and free radicals through single-electron transfer; simultaneously, Nuclear Fast Red can spontaneously and irreversibly embed into DNA grooves, forming non-fluorescent complexes. Nuclear Fast Red is commonly used as a counterstain in biological experiments.[3]

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:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent 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 DMSOTargetMol | reagent (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 DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
All types of co-solvents required for the protocol, such asDMSO, PEG300/ PEG400, Tween 80, SBE-β-CD, corn oil are available for purchase on the TargetMol website with a simple click.
