Biological Activity

Description Evans Blue (Direct Blue 53,C.I.23860) is a potent inhibitor of the uptake of L-glutamate into synaptic vesicles, also an AMPA/kainate receptor antagonist.
Targets
AMPA/kainate receptor [7] vesicular glutamate uptake [5]
87 nM
In vitro
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
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].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
