Biological Activity

Description Taurine is an organic acid widely distributed in animal tissues.
In vitro

Taurine is present in high concentration in algae and in the animals including insects and arthropods, but is generally absent or present in traces in the bacterial and plant kingdoms. [1] In cardiac tissue alone, taurine levels of 20 mM or higher may be found. Taurine availability protects against cholestasis induced by monohydroxy bile acids remains confined to guinea pigs. [2] In addition, Taurine is an essential nutrient for the cat. [3] Oral supplementation of taurine results in increased plasma taurine concentrations and is associated with normalization of left ventricular function in both groups of cats. Myocardial concentrations of taurine are directly related to plasma concentrations and low plasma concentrations are found to be associated with myocardial failure in cats, proposing a direct link occurs between decreased taurine concentration in the myocardium and decreased myocardial mechanical function.

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.
