Poros® (Perseptive Biosystems)

Spherical Polystyrenedivinylbenzene: For bio-molecules with Perfusion Chromatography.

Two different phase exist:
R1 for very hydrophobic proteins and petides - R1 compares to a C4-phase.
R2 for general reversed phase separation of proteins, peptides and nucleic acids - R2 compares to a C8-phase.
