CLEAR IT™
Protein Depletion Technologies
ClearIT™ is a flexible approach to protein depletion and
recovery for serum/plasma and other biological fluids developed and
patented by HealthLinx. The technology consists of immunoglobulins
isolated from avian egg yolk (IgY) raised against specific sets of
proteins. The combination of different IgY fractions from chickens
immunised with specific sets of protein antigens facilitates
specific depletion (and recovery) of proteins prior to separation
and analysis. Using ClearIT™, researchers can now become far more
targeted and focused by targeting specific sets of proteins with
specific applications in life sciences.
ClearIT™ facilitates the production of both single-use disposable
and multiple use columns that are cost-effective. This technology
is protected by patent applications that are in different national
phases in Australia, US, Canada and Japan, with the patent recently
granted in Europe. The use of IgY preparations offers several
advantages including relatively low cost of production, flexibility
of production scale and product development. Furthermore,
immunoglobulins derived from multiple antigen immunisations can be
combined to deplete certain combinations of antigens.
Therefore, ClearIT™ provides unique flexibility in matching
different combinations of affinity reagents more cost-effectively
for selective depletion of desired proteins against different
applications:
- Custom combinations of IgY matrices can be developed for a
variety of applications such as 2D gel electrophoresis, liquid
chromatography, and mass spectrometry;
- The technology has application across a variety of biological
samples such as serum/plasma, CSF, urine, lung lavage, and other
biological fluids;
- All biological samples have different relative ratios of
abundant proteins, demanding the generation of specific protein
depletion/enrichment strategies to accommodate particular research
needs.
ClearIT™ has the capacity to meet this demand and provide
customised depletion technologies for specific applications,
including samples from different biological species. ClearIT™ can
be combined with other depletion products such as those that are
based on dye affinity (Cibacron blue) or single antigen specific
monoclonal antibodies.
