Brevetoxin 3 is a neurotoxin produced by the dinoflagellate K. brevis.1,2 It binds to site 5 of voltage-gated sodium channels (Navs), prolonging the mean open time and inhibiting inactivation of these channels.2 Brevetoxin 3 induces the release of lactate dehydrogenase (LDH), L-glutamate, and L-aspartate from primary rat cerebellar granule neurons (CGNs; EC50s = 30.9, 45.3, and 50.2 nM, respectively).3 It induces convulsions in, and is lethal to (LD50 = 4 ng/egg), Japanese rice fish embryos.1 Brevetoxin 3 has been found in water samples collected during red tide blooms.4

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Calculation results:
Working concentration: mg/ml;
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.
