What does PFF mean in UNCLASSIFIED

What it Means

Protein free filtration is an important process in biochemistry, as it allows scientists to effectively separate proteins out from other substances present in a sample. This type of filtration involves passing a liquid sample through a membrane with pores small enough that only certain molecules or compounds can pass through while others are blocked by the membrane itself. In the case of PFF specifically, this means that any proteins that may be present in the sample won’t make it through – instead they remain stuck on the other side of the membrane while everything else passes through into what is known as the “filtrate”.

Applications

The main application for protein free filtration is removing unwanted proteins from a sample before performing further tests or experiments on it. This helps ensure that the results are unaffected by any proteins which could interfere with the desired outcome of an experiment. In addition, PFF can also be used to determine microbial contamination levels within a particular environment – since most microbes can’t pass through such tiny pores they will tend to get stuck behind on one side of the filter, thus making their numbers easy to estimate when counting up what’s left after filtration has taken place.

Another useful application for PFF involves studying specific molecular interactions within biological samples, such as those involving enzymes or other catalysts which can induce chemical reactions at certain temperatures and/or pH levels. As these molecules won’t pass through filters designed for removal of proteins, they are easily separated out during protein-free filtration and can then be studied more closely afterwards without interference from any other substances present in solution with them at the time.
