• Product summary: 

STYROS™ 1R and STYROS™ 2R are the first two generations of our reversed-phase polymeric stationary phases. They offer high protein capacity, high pressure tolerance and the possibility to be used in scale up processes since they do not leach and therefore contaminate the final product.
The fully pervious nature of the media with a unimodal pore structure enables exceptional mass transport kinetics.
STYROS™ 1R has a binding strength equivalent to that of a silica C4, whereas the binding strength of STYROS™ 2R is closer to other poly(styrene-divinylbenzene) media such as POROS® R from PerSeptive Biosystems or PLRP-S from Polymer Laboratories.

• Key Features:

Feature 1:

High protein capacity (measured with Lysozyme)

15 mg/ml for STYROS™ 1R and

10 mg/ml for STYROS™ 2R

Feature 2:

Although we have used pressures of up to 10,000 psi without irreversibly altering the structure of the bed, we recommend the following pressure limits:

4,000 psi for the XH series,

3,000 psi for the XP and XM series.

4,000 psi for the NB series 

4,000 psi for the MB series

 

Feature 3:

No measurable shrinking and/or swelling due to highly crosslinked nature of the stationary phase.
