Sepmag awarded Chinese patent for homogenous biomagnetic
separator
24 Jan 2011
Barcelona-based Sepmag, a manufacturer of biomagnetic
separation systems for the in vitro diagnostics market, has
received a Chinese patent for its innovative homogenous magnetophoresis
technology.
The patent was granted for the unique methods and devices for the
homogeneous separation of magnetic particles — a technique that
applies less pressure on particles and guarantees users consistently
reproducible results in their in vitro diagnostics kits.
Gaining the patent forms part of Sepmag’s commercial strategy for
targeting the Chinese market. The company has already commenced
shipping the Sepmag Q250ml to CapitalBio, its first client in the
region, for the processing of large batch volumes in protein
purification. Following the success of this contract, it intends to
actively market itself to diagnostic companies across China looking
for more sophisticated solutions that allow for greater sensitivity,
as an alternative to traditional technologies like enzyme-linked
immunosorbent assays (ELISA).
The company's precision magnetophoresis systems, unlike other
biomagnetic separation processes, produce a completely homogeneous
magnetic field, which applies the same magnetic force on beads
regardless of the distance from the magnetic ring.
Using conventional separators, beads that are further away from
the magnet will be harder to manipulate and those that are closer
may experience an excessive force, often resulting in bead
aggregation, loss of activity and resuspension problems. In
contrast, Sepmag’s unique magnet alignment vastly reduces the
variability of the end product, enables a more straightforward
scale-up process and greatly simplifies revalidation processes.
Josep Maria Simó, CEO, commented: “We are delighted that the
Chinese Patent Office has granted Sepmag a patent for our unique
magnetophoresis techniques. This will allow us to further
consolidate our Far-East presence, having already established a
strong and growing foothold in Japan. Over the next couple of years,
we forecast the Chinese marketplace to be amongst the fastest
growing for biomagnetic separation systems. The agreement we have
signed with CapitalBio marks the start of a significant expansion in
the region and a continuation of the internationalisation of Sepmag
technologies.”
