IPTG for RNAi

Hi,
Has anyone directly compared the IPTG from Thermo, Invitrogen, and/or Sigma?
It looks like the Thermo IPTG is half the cost of the other two, and I am hoping to make sure
that doesn’t mean it is half as good.
Thanks,
Claire

I pay $75/10g of IPTG from US Biological (that’s the pricing for GSA members) and it works just fine in my hands. I haven’t tried it, but our contract pricing with MidSci is $44/5g and $157/25 g but I haven’t used MidSci’s IPTG.

Hi Claire,

We use IPTG from Gold Bio (https://www.goldbio.com/products.php?isSearch=Y&keyword=IPTG) and it works wonderfully (it’s almost a deal too good to be true…)
