San Diego, California—June 14, 2011. Solulink, Inc., a leading innovator of state-of-
the-art linking reagents, easy-to-use conjugation kits, and conjugation services for the
life science research, diagnostics, and pharmaceutical markets, today announced it has
launched a new higher binding streptavidin agarose, Streptavidin Agarose Ultra
Performance™.
Solulink’s Streptavidin Agarose Ultra Performance™ was specifically developed with
several key parameters in mind — high biotin binding capacity and low non-specific
binding, on an agarose support which would support high flow rates with consistent
permeation. These qualities make it an ideal media for applications such as
immunoprecipitation (IP), co-immunoprecipitation (co-IP), chromatin immunoprecipitation
(ChIP), affinity purification, cell capture, etc. Solulink utilizes a recombinant streptavidin
which is of high purity, possessing much lower non-specific binding than avidin due to its
lower isoelectric point and lack of glycosylation. This streptavidin is immobilized via
Solulink’s proprietary linking technology, resulting in highly stable immobilizations with
minimal protein leaching. Moreover, unlike other conjugation chemistries such as
cyanogen bromide, Solulink’s conjugation process leaves the agarose with no net
charge which could otherwise interact with biomolecules to cause unwanted binding. Our
core agarose is specially formulated to be of unparalleled uniformity, with a relatively
small mean diameter of 35µm. This, combined with its high level of crosslinking, creates
a resin which is tolerant of high flow rates or centrifugal forces often experienced in high-
throughput screening applications and immunoprecipitations.
Based on immunoprecipitation of ß-actin in a study, Solulink’s Streptavidin Agarose Ultra
Performance™ captured at least 2 times more antigen than competing streptavidin
agarose products under identical conditions. This increased binding capacity, along with
its rigid core beaded agarose, makes it the ideal medium for capture of biotinylated biomolecules at all scales. The medium may be used either in batch format or packed
into chromatography columns to suit the scale and process at hand.
