About PPS Silent® Surfactant



How Does It Compare
to Rapigest?
Why Do You Say It's For Membrane Proteins?

Using PPS Silent Surfactant is simple. The cleavage products of PPS are fully soluble so there's no oily pellet to remove. PPS and Rapigest both allow researchers to identify more unique proteins, but each detergent extracts a different set of proteins, with some overlap between the sets.

Hydrophobicity Index analysis and GO ontology analysis of proteins identified from samples prepared using PPS show a significant bias for membrane protein extraction and solubilization.
