Biotech
Support Group announces receipt of a NEW JERSEY COMMISSION ON
SCIENCE, INNOVATION AND TECHNOLOGY Phase II Catalyst Research Award
of $40,000.
The
Research Award entitled “
Evaluating
the NRicher™ Bead Platform for Targeted LC-MS Quantification”
will be conducted at The Rutgers Biological Mass Spectrometry
Facility. This award follows from the Catalyst Phase I Award
demonstrating simple workflows that generate low abundance enrichment
of sub-proteomes suitable for quantitative plasma proteomics.

The
article states we used affinity beads (NuGel PROspector)
to pre-enrich Toxoplasma gondii lysate to capture five distinct
subproteomes. [Note: NuGel PROspector beads are now part of the
NRicher™ platform.]. When comparing the 5 different
subproteomes, there is clearly different selection biases amongst the
5 surface chemistries. Also, many of the proteins observed from the
NRicher™ beads, were not observed in the Ion exchange
fractions demonstrating the importance of combining different modes
(ionic, hydrophobic, etc.) of separation to alter selection
properties, and consequently improving overall proteome coverage.

simplified and diversified workflows for sub-proteome and biomarker
enrichment – Poster HUPO World Congress 2024
After
NRicher™ sample prep, target peptides have highly enhanced
spectral signal. NRicher™ sub-proteome enrichment can
minimize acquisition time, collectively improving overall throughput,
cost, and productivity. Specific target peptides that report
functional PTMs and amino acid variant regions promise insights and
potential multiplex biomarkers for disease.

Six
different NRicher™ beads (described with an old tradename
PROspector) were used as an enrichment step in the overall workflow;
about twice the number of observations and annotations became
possible. This further validates that the sub-proteome bias
characteristics of the NRicher™ surface chemistry platform
can simplify complex proteomes into enriched sub-proteomes with
efficiencies suitable for deep functional proteome
characterization.

- NRicher™: A Low Abundance Proteome Enrichment Platform With
Seamless Integration of On-Bead Digestion
The
NRicher™ Advantage is described: • Consumable chemically derived
NuGel™ beads, species agnostic as they are not derived from
antibodies • Does not require any specialized instruments, just a
standard microfuge • Use of bead cocktails allows for one, rather
than multiple LC-MS analyses • Functionally active sub-proteomes
after separations, for any orthogonal functional, enzymatic, or
immunoassay analysis

The
need for new biomarkers to support personalized healthcare, has
fostered numerous proteomic innovations. Still, a number of
challenges remain. One is the preponderance of high abundance
proteins and, concurrently in targeted proteomic workflows,
efficiency and consistency in quantifying target peptides from
different sample cohorts. This is in part due to the changing
landscape of proteins/peptides not associated with the selected
targets. A solution for both these challenges is now available
through a suite of products called NRicher .
