Sample Requirements

SAMPLE REQUIREMENTS

Serum / Plasma

50 μL

Tissue

30 mg

Cells

1–5 × 10⁶ cells

Feces / Gut Content

100 mg fresh / 20 mg lyophilized

Urine

Analysis Examples

ANALYSIS EXAMPLES

Example figures are generated from real project data; actual figures and analyses depend on the detection panel and study plan.

T-test Bar Chart

All metabolites sorted by ascending p-value; grouped bars show group means ± SD with p-values annotated beside the bars.

Hierarchical Clustering Heatmap

Z-score normalized abundance patterns of all metabolites; rows ordered by hierarchical clustering — red for high, blue for low abundance.

Disease Association Bar Chart

Known metabolite–disease associations mined from HMDB and other databases, ranked by the number of associated metabolites.

Metabolite Abundance Analysis

Faceted boxplots of significantly different metabolites between groups; intergroup comparison by Welch's t-test.

Bar Chart Analysis

Per-sample bar charts of differential metabolites, visualizing group differences and individual dispersion.

FAQ

How long does a PFAS Panel project take?

Mature targeted panels typically take 1-3 weeks; untargeted projects take 2-4 weeks (counted from sample receipt and QC approval). The exact timeline is confirmed in writing before project start, and progress is trackable on the OmicsHub cloud platform.

What if my sample amount is below the recommendation?

Please do not dilute your samples. Low-input samples can often be accommodated by adjusting the preparation workflow — tell us the actual amount and our technical team will assess feasibility and note adjustments in the study plan.

Can I add targets to an existing panel?

Yes. Mature panels support on-demand additions; novel analytes outside the list can be implemented through custom method development (requires standards and extra validation time) — see our Custom Targeted Metabolomics service.

What samples do you need for PFAS Panel?

Serum/plasma ≥100 μL (fasting, no haemolysis), tissue ≥50 mg (snap-frozen), cells ≥1×10⁶ (medium washed off), urine ≥200 μL. Keep fasting time consistent, aliquot into single-use volumes and avoid freeze–thaw. Full guidance: Technical Resources → Sample Guide.
