Zymo sell kits for yeast plasmid isolation, however I have read that you can basically just digest the yeast cell wall separately (with zymolyase treatment), then just use a Qiagen miniprep (for...

I transformed a plasmid into yeast and selected for transformants by growing them in a selective media (liquid, not agar plate). My experiment requires that I continually grow/ split these...

I typically don't adjust the pH of my CSM (SC-HIS) or YPD media when growing yeast, and wondered if it had a significant effect on growth? After measuring both, YPD seems fairly neutral however...

I am also a little confused as to what happens if you were to take mid-log cells (for examples' sake say OD600 ~0.3-0.8) and dilute to below 0.3. Do they slow their growth rate in a quorum...

I am having difficulty finding an answer to this question - what is the maximum DNA insert length feasibly permitted by MiSeq. By 'DNA insert', I mean EXCLUDING the adapters. And does anyone know...

I've purified my plasmid from DH5a for a double digestion (NcoI and XhoI), however I've noticed it only appears to be cleaving at one site (ie I'm only getting one band in the gel). Previously it...

I am still relatively new to working with yeast, so was wondering what happens if you leave yeast at 30 for longer than you need to so that they go on to form big fat colonies? I imagine on...

I have come across some protocols that suggest using pre-cultures that are cells grown from a plate colony over the weekend to stationary then left on the bench at room temperature, that you can...
