Hello everybody,

I'm currently trying to dissolve a carotenoid (Astaxanthin). I did it in ethanol, DMSO and Polyethylene glycol.

But the problem is that these 3 solvents interfere with the subsequent analyses I'm trying to do.

Does anybody have an idea what other solvent I could test?

It should be miscible in water and not have toxic effects on cells and membranes.

Thanks in advance for any suggestion

Have a nice weekend

I use a 4:3 Ethanol-hexane solvent myself

You may want to try acetonitrile. I'm not an expert on the relative toxicity of solvents, but if your cells can handle DMSO then acetonitrile shouldn't pose a problem.

 

It would be helpful to know what kind of analyses you are running, and how the other 3 solvents are interfering...
