ToyoScreen prepacked columns for process
development
ToyoScreen columns packed with the full range of our
TOYOPEARL IEC products are available in 1 mL and 5 mL
resin volumes. The ToyoScreen columns provide a conve-
nient way to perform early resin screening for both target
retention and recovery. Multiple columns can be connected
in series for additional capacity or resolution. Please see the
ordering information at the end of this section or contact us
for more information on these products.
The most popular TOYOPEARL ion exchange resins are now
also availabe as ToyoScreen RoboColumns. ToyoScreen
RoboColumns are miniaturized chromatographic columns
pre-packed with TOYOPEARL media. These columns are
available in different volumes and can be operated with
a robotic liquid handling system, such as the Freedom
EVO
®
from TECAN. This approach allows automated high-
throughput, small-scale biochromatographic separations of
protein samples by running up to eight individual columns
simultaneously.
LabPak
For scientists wishing to develop a better physical under-
standing of the packing properties of TOYOPEARL and
TSKgel ion exchange resins, we offer TOYOPEARL LabPaks
containing small volumes of the bulk resins. Please see the
ordering information at the end of this section or contact us
for more information on these products.
Summary
Since 2007, major additions have been made to the
TOYOPEARL ion exchange resins offered by Tosoh
Bioscience.The TOYOPEARL GigaGap family of resins and
the new TOYOPEARL Q-600C AR media represent signifi-
cant improvements in terms of dynamic binding capacity,
elution kinetics, and alkaline stability. When these products
are used, process developers have more options available
to design and optimize their process to improve produc-
tivity and lower operating costs.
