I am contemplating using a CyQuant line of dyes from Life Technologies (LT). But there are two types which are confusing me: CyQuant Direct and CyQuant NF. From their description, the only difference seems to be that the Direct needs the removal of a supernatant in a well-plate format. I was further confused by a tech rep from LT who told me CyQuant just gives you a total count of live and dead cells, contrary to what I read in the description.
