Product Introduction

Bioactivity
Description
Evans blue (C.I. 23860) is an azo dye, inhibits L-glutamate uptake via the membrane-bound excitatory amino acid transporter (EAAT).
Targets&IC50
Glutamate uptake (vesicular):87 nM
In vitro
Evans Blue is found to be inhibiting DNA binding of NF-κB at a low concentration of 100 μM[1]. It has proven over the years to be a dependable stain for microscopic determination of cell death[2]. Evans Blue is also a known blocker of a subset of a-amino-3-hydroxy-5-methyl-isoxazole/kainate receptors (IC50=355 nM) for the subunit combination GluR1,2[5]. Evans blue is the first known δ-subunit-specific antagonist of ENaC and activates large-conductance Ca2+-activated K+ channels in sheep bladder myocytes and cultured endothelial cells of human umbilical veins[5].
In vivo
Evans blue pretreatment could inhibit the mast cells degranulation and that may be the main mechanism for prevent animals from C48/80-triggered anaphylaxis and systemic inflammation[4]. Evans blue modulates the non-N-methyl-d-aspartate receptor in rat thalamic neurons, blocks the P2X-purinergic receptor in rat vas deferens, and inhibits the glutamate transporter in rat brain synaptic vesicles[6].

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% 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 μLddH2OTargetMol | reagent mix well and clarify
