JUNCTION, NJ
, June
24, 2022 -- Biotech Support Group reports on an article, describing
the simplicity and efficiency of their lipid clearance sample
preparation technology to improve a nanopore sensor peptide signature
in order to identify and detect target peptides derived from two
Mycobacterium tuberculosis (Mtb) virulence factors in serum. The
citation is:
Zheng, Wenshu, et al. " Nanopore-based disease diagnosis using pathogen-derived tryptic peptides from serum ." Nano Today 45 (2022): 101515.
Recent studies indicate that current signatures produced by peptide-nanopore interactions can distinguish high purity peptide mixtures, but the utility of nanopore sensors in clinical applications still needs to be explored due to the inherent complexity of clinical specimens. For this, the study describes a methodology to select trypsin-digested peptide biomarkers suitable for use in an immunoprecipitation-coupled nanopore (IP-NP) assay, to produce a characteristic nanopore interaction signature. A technical hurtle was overcome as at first, Nanopore analysis of samples resulted in frequent and prolonged pore blockades and unstable current baselines. This appeared to result from lipid or lipoprotein complexes that were non-specifically adsorbed by the immunoprecipitation matrix. This was markedly reduced when samples were lipid extracted before immunoprecipitation.
“Lipids can often interfere with many analytical platforms for measuring proteins and peptides. I am very pleased to see that this article demonstrates the efficiency of Cleanascite™ over another common commercially available reagent. Now with this simple and fast sample prep step, better methods to diagnose infectious disease based on peptide biomarkers may be soon forthcoming” states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.
