OmniProt™ Elevates Your Research!
OmniProt™ is a group of high-performance beads/nanoparticles, which offers a better way to enrich low-abundance proteins, improving sensitivity and reproducibility in the preparation of plasma/serum samples for proteomic mass spectrometry analysis.
OmniProt™ workflow
OmniProt™ is ideal for lab - scale experiments and rapid tech development. Its flexible design allows easy customization of each step, enabling precise research and fast-paced innovation without rigid protocols. A reference protocol is provided below, and we eagerly anticipate your laboratory developing even more efficient protocols.

①Sample
Mammalian plasma/serum samples (human or mouse).
②Enrichment
Incubate samples with OmniProt™ beads at 30 ℃ for 30 min to form protein corona(Soft/Hard).
③Lysis
Remove excess proteins, then lyse, reduce and alkylate to prepare proteins for digestion.
④Digestion
Digest proteins into peptides using trypsin.
⑤Cleanup
Desalt and purify peptide mixtures before LC-MS analysis.
⑥MS Analysis
Run LC-MS/MS using TMT (30fractions) or Astral DlA (60samples/day).
OmniProt™ working principle
· Using a Scanning Electron Microscope (SEM) to view the enrichment:


1. Original nanoparticles are uniformly spherical with a radius of about 441-464 nm.
2. After protein binding, nanoparticles develop a dynamic protein corona, increasing the radius to approximately 467-532 nm.
· Dynamic protein corona - powered selective protein enrichment:

OmniProt™ uses nanoparticles that form a dynamic protein corona when exposed to plasma or serum, creating a biological interface that enables selective enrichment of proteins across various abundance levels. [1]
By engineering a protein corona through nanoparticle-plasma interactions, OmniProt™ significantly enhances the identification of low- and medium-abundance proteins in human and mouse plasma/serum samples.
Baize will tell the truth!
To ensure data quality and interpretability in NP-based plasma proteomics, researchers at Westlake University developed an open-access software, Baize, for evaluating sample contamination caused by platelets, erythrocytes, and coagulation-related proteins.
