(That’s the nitrile functional group for you; there’s nothing else quite like it). It’s no DMSO, but then again, DMSO’s boiling point is three times a lot higher, and compared to acetonitrile it pours.

Silly question: is DMSO sterile by itself, to add it to cells? – Lab stock bottle could be used? (Aug/22/2005 ) I just wonder, could i use for the purpose of cell freezing DMSO, which is standing on the lab shell, or I should buy a new bottle and to use it only for cell culture, or I could sterilize DMSO?

X-GAL is soluble in N, N-dimethylformamide or dimethylsulfoxide (DMSO). Together with appropriate bacterial cloning vectors, host strains, and IPTG, X-GAL provides an easy way to distinguish between.

We buy sterile DMSO from sigma. It comes in sealed glass 10 ml vials. I work with some very hydrophobic compounds that I add to media. I dissolve the compounds in the sterile DMSO & just add it to media. In 2 years, I haven’t had any contamination. But my compounds are kind of toxic at the stock concentrations. This looks like what we use.

X-Gal is the common short name for 5-bromo-4-chloro-3-indolyl-β-D-galactopyranoside. It is a substrate for beta-galactosidase (lacZ) and turns blue upon being cleaved. It is commonly used for blue-white screening or detection of LacZ transgenes in cells and tissues.

X-Gal is used to identify ß-galactosidase activity and DNA insertion in the LacZ region of the plasmid. X-Gal with IPTG is essential for blue-white screening.

When I was inexperienced, one of my very mistakes was to filter sterilise DMSO without diluting it. To my horror, the filter dissolved! So, what I do now is to dilute the DMSO (for common lab use should be OK) in my culture media to achieve the final concentration, and then filter sterilise the mixture.

X-gal is an organic compound consisting of galactose linked to a substituted indole. The compound was synthesized by Jerome Horwitz and collaborators in Detroit, MI, in 1964. The formal chemical name is often shortened to less accurate but also less cumbersome phrases such as bromochloroindoxyl.
