EV isolation and characterization are only the first step. To investigate what a preparation contains, what information it carries and what functions it may have, researchers use omics analysis.
Plant-derived extracellular vesicle omics research has grown rapidly: transcriptomics investigates miRNA/lncRNA regulatory networks, proteomics examines protein composition, and metabolomics identifies small-molecule constituents. These complementary approaches address different questions. This guide covers selection, method comparison, sample requirements and deliverables.
Step 1: Define the research question
| Research question | Recommended approach |
|---|---|
| Which miRNAs or lncRNAs are present in EVs, and could they target particular pathways? | Transcriptomics(miRNA / LncRNA) |
| Which functional proteins are on or inside EVs? | Proteomics (DIA) |
| Which small molecules do EVs carry, such as sugars, amino acids, flavonoids and phenolics? | Metabolomics(LC-MS/MS) |
| Which lipids are present in EV membranes? | Lipidomics(LC-MS) |
| Do EVs contain nucleic acids of microbial origin? | Microbiome (Nanopore 16S) |
Step 2: Check sample quantity (see the sample guide below)
Step 3: Decide whether to integrate multiple omics layers —Integrating omics layers, such as transcriptomics and proteomics, can support cross-checks at different molecular levels for mechanistic research.
| Omics | Method / platform | Reference price | Turnaround | Recommended sample input |
|---|---|---|---|---|
| miRNA sequencing | Qiaseq library preparation + Illumina sequencing (10M reads / 3G RAW) | 1000 CNY/sample | 20 business days | RNA 10 ng (minimum 1 ng) |
| lncRNA sequencing | Smart-seq library preparation + Illumina (10G raw data; standard lncRNA + mRNA analysis) | 1000 CNY/sample | 20 business days | RNA 10 ng (minimum 1 ng) |
| Proteomics | DIA technology, Thermo Astral platform | 1000 CNY/sample | 20 business days | EV sample / protein: 10 μg |
| Metabolomics | Untargeted metabolomics LC-MS/MS, QE / HF-X platform | 300 CNY/sample | 20 business days | EV sample / protein: 10 μg |
| Plant metabolomics | Untargeted metabolomics LC-MS/MS (covering sugars, amino acids, nucleotides, alkaloids, flavonoids, phenolics and more) | 500 CNY/sample | 20 business days | EV sample / protein: 10 μg |
| Lipidomics | Relative lipidomics quantification by LC-MS/MS, QE / HF-X platform | 600 CNY/sample | 20 business days | EV sample / protein: 10 μg |
| Omics | Sample type | Recommended amount | Minimum amount | Storage |
|---|---|---|---|---|
| Transcriptomics (miRNA / lncRNA) | EV RNA | 10ng | 1ng | −80°C; ship on dry ice |
| Proteomics (DIA) | EVs / protein | 10μg | — | -80℃ |
| Metabolomics / lipidomics | EVs / protein | 10μg | — | -80℃ |
| Microbiome (16S) | EV DNA | 50 μg (or 20 ng DNA) | — | -80℃ |
| Genome (WGS) | EV DNA | 50 μg (or 20 ng DNA) | — | -80℃ |
The source recommends basic characterization, including particle size, concentration and markers, before submission. Supplied EV samples require RNA extraction and capillary electrophoresis quality control first (200 CNY/sample; two business days).
Q1: Can a small amount of a precious sample be used for omics?
A: The source lists a minimum RNA input of 1 ng for transcriptomics and suggests enriching low-input samples by magnetic capture or ultrasonic nanofiltration before omics.
Q2: Can transcriptomics, proteomics and metabolomics be integrated?
A: Yes. Combined analysis can cross-check different molecular layers. Confirm the analysis requirements when submitting samples.
Q3: How do plant and animal EV omics differ?
A: Analysis can use the target species’ reference genome and annotations together with its transcriptome, a related species’ genome or de novo assembly. Where high-quality references are unavailable, the report should identify data sources, alternative strategies and limitations; homology predictions should not be described as experimentally validated functions.
Q4: How long does omics analysis take?
A: The source lists approximately 20 business days for routine transcriptomics, proteomics or metabolomics, including raw data and a standard analysis report.
Q5: Can the sequencing platform be specified?
A: The source lists Illumina for transcriptomics, Thermo Astral for proteomics and QE/HF-X for metabolomics by default. Customized platform or depth requirements can be discussed for a separate quotation.
