Should I change the concentration Proliferum® LSR 10X if I use more/less than 10% FBS currently?

Yes - Proliferum® LSR 10X is designed to be be a 1:1 replacement for FBS. For example, if you are replacing 20% FBS, make sure to double the corresponding Proliferum® LSR volume.

Do I need to do adaptation when switching to Proliferum® LSR?

There is typically no need to undergo adaptation for most cell types. However if you experience some difficulty in growing your cells with Proliferum® LSR, we can recommend an adaptation protocol. Here you can access the full table of attachment proteins we have successfully tested.
