Default freezing yeast

I know from working in a microbiology lab that the way to freeze bacteria and yeast is to freeze them in a mixture of glycerine and broth. Has anyone done this to keep your yeast genetically same?
The idea would be to keep the yeast frozen then transfer it to a slant and then to a starter. It would also take up no fridge space and minimal freezer space, keeping the wife happier.
Thanks,
scott

Yes, there are threads on this forum about freezing yeast. Never done it. I just chill my yeast harvested from split starters.

Done it lots. Loads of other people here too. Works great, but the time and materials to build up the small frozen sample wasn't worth it to me. I just save much larger jars of yeast trub from previous batches. Works better IMO.
