ACYLCARNITINE PROFILING

Acylcarnitines Panel

Acylcarnitine Profiling — Absolute Quantification

Acylcarnitines are the carrier forms that shuttle fatty acids into mitochondria for β-oxidation; their chain-length profile directly reflects mitochondrial utilization of short-, medium- and long-chain fatty acids, making them routine markers of mitochondrial dysfunction, fatty-acid oxidation defects and newborn screening. This service absolutely quantifies 30+ acylcarnitines (including free carnitine) for research on energy metabolism, cardiac and skeletal-muscle metabolism, metabolic diseases and drug-induced mitochondrial toxicity.

FAQ

FAQ
How long does a Acylcarnitines 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 Acylcarnitines 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.

Delivery timing: sample shipping, customs declaration and similar steps may extend turnaround; actual project timelines prevail.
