Apolipoproteins play a key role in atherosclerotic processes. Apo E variants are under investigation in neurological disorders, and in cancer there is evidence for modulating apolipoprotein expression. Thus, profiles of circulating apolipoproteins hold promise as biomarkers for the prediction of cardiovascular disease (CVD) and other precision medicine applications. However, clinical immunoassays are not available for most apolipoproteins, and variants require special consideration. For example, the size polymorphism of Lp(a) necessitates a need for isoform-agnostic measurement. Thus, advances in the productivity and multiplexing capacity of LC-MS/MS, offer the potential for personalized profiling by simultaneous quantification of multiple apolipoproteins and their associated variants.

The NRicher™ Apo product is dedicated to Apolipoproteins to help in these investigations. Another BSG product - Cleanascite™ binds to only lipid-bound proteins, and can be used to investigate the lipid-bound vs. unbound profile. This may provide additional granularity to CVD risk assessment.

New JerseyCommission On Science, Innovation And Technology Phase II CatalystResearch Grant Awarded to Biotech Support Group

BiotechSupport Group announces receipt of a NEW JERSEY COMMISSION ONSCIENCE, INNOVATION AND TECHNOLOGY Phase II Catalyst Research Awardof $40,000. TheResearch Award entitled “ Evaluatingthe NRicher™ Bead Platform for Targeted LC-MS Quantification” will be conducted at The Rutgers Biological Mass SpectrometryFacility. This award follows from the Catalyst Phase I Awarddemonstrating simple workflows that generate low abundance enrichmentof sub-proteomes suitable for quantitative plasma proteomics.

Thearticle states we used affinity beads (NuGel PROspector)to pre-enrich Toxoplasma gondii lysate to capture five distinctsubproteomes. [Note: NuGel PROspector beads are now part of the NRicher™ platform.]. When comparing the 5 differentsubproteomes, there is clearly different selection biases amongst the5 surface chemistries. Also, many of the proteins observed from the NRicher™ beads, were not observed in the Ion exchangefractions demonstrating the importance of combining different modes(ionic, hydrophobic, etc.) of separation to alter selectionproperties, and consequently improving overall proteome coverage.

After NRicher™ sample prep, target peptides have highly enhancedspectral signal. NRicher™ sub-proteome enrichment canminimize acquisition time, collectively improving overall throughput,cost, and productivity. Specific target peptides that reportfunctional PTMs and amino acid variant regions promise insights andpotential multiplex biomarkers for disease.

Sixdifferent NRicher™ beads (described with an old tradenamePROspector) were used as an enrichment step in the overall workflow;about twice the number of observations and annotations becamepossible. This further validates that the sub-proteome biascharacteristics of the NRicher™ surface chemistry platformcan simplify complex proteomes into enriched sub-proteomes withefficiencies suitable for deep functional proteomecharacterization.

NRicher: Family Specific Enrichment For Targeted Proteomics – Poster USHUPO 2024

Theneed for new biomarkers to support personalized healthcare, hasfostered numerous proteomic innovations. Still, a number ofchallenges remain. One is the preponderance of high abundanceproteins and, concurrently in targeted proteomic workflows,efficiency and consistency in quantifying target peptides fromdifferent sample cohorts. This is in part due to the changinglandscape of proteins/peptides not associated with the selectedtargets. A solution for both these challenges is now availablethrough a suite of products called NRicher .

Do BSG's products work for all species?

Yes, as our products are not derived from antibodies, they are species agnostic, and have applied to humans, mice, rats, guinea pigs, goats, cows, pigs, even frogs and fish.

Can you supply bulk material only (from the kit-based products) for large volume orders?

Yes, we can adjust all of our kit products, to supply only the beads. For large orders, whether kit or bulk material, we provide special discounted quotations. Please inquire.

Can the protocol be scaled to accommodate different amounts of either volume or mass?

Yes, we provide general guidelines for use, but the protocols can usually be adjusted to accommodate either larger or small starting samples, or larger or smaller starting concentrations. We recommend first contacting us for guidance in adjusting the protocol.

Can the products be adapted to high throughput formats and automation?

Although we do not have an off-the-shelf product for 96-well formats currently, we have ongoing collaborations that can provide such formats. Please inquire.

Are the products compatible with detergents?

This has not been fully investigated, but we do not recommend use of SDS. Low concentrations, 0.1 – 0.5% of non-ionic detergents have been used with some of our products, but to what extent they alter separation performance, is unknown. If non-ionic detergents are to be used, generally we recommend that they be of no greater than 0.1% before applying to the beads. So for tissue lysates for example at higher %, dilute the sample before application.

What is the stability and shelf life of the product?

The products have a shelf life typically 6 months to 1 year. We ship at room temperature, but recommend storage at 4°C upon receipt. Do not freeze.

Do the products contain any biologically derived material?

All of our products are derived chemically, not biologically, with one exception. The "PLUS" products contain recombinant Protein A.

How can I order?

We can take on-line cart orders, which accept North American credit cards, Visa & MasterCard. It does not however, accept other international credit cards. If you would like to order direct, contact us at [email protected]. In the US, distributors Fisher Scientific and VWR can be used to order all products, even those not listed on their sites, just provide them with our catalog #. A full list of international distributors is listed on How to Order | Biotech Support Group LLC.
