Cardiovascular & LipidologyLipoprotein Lipase Co-factor

Apolipoprotein C2 (ApoC2)

Surface apolipoprotein on chylomicrons and VLDL that serves as the essential, obligatory co-factor for lipoprotein lipase (LPL).

Standard Range2.0 - 6.0 mg/dL
Optimal Longevity3.0 - 5.0 mg/dL
Measurement Unitmg/dL
Organ SystemLipoprotein Lipase Co-factor
Routine Panels:Lipoprotein Lipase Activation PanelSevere Hypertriglyceridemia

Standard vs. Optimal Reference Rangesmg/dL

Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.

Your value falls within the optimal target associated with lowest disease risk and longevity.

Standard Reference Interval

2.0 - 6.0 mg/dL

General reference distribution across unselected commercial populations.

Optimal Longevity Target

3.0 - 5.0 mg/dL

Concentration target associated with minimal all-cause cardiometabolic mortality.

Molecular Mechanism & Clinical Purpose

Binds the catalytic domain of endothelial LPL to activate hydrolysis of core triglycerides into free fatty acids.

Differential Diagnosis

Elevated Levels (ApoC2 High)

  • •Familial hypertriglyceridemia with functional resistance
  • •Metabolic syndrome with elevated VLDL

Low Levels (ApoC2 Low)

  • •Familial ApoC2 deficiency (severe chylomicronemia, eruptive xanthomas, pancreatitis)
  • •Secondary LPL failure

Technical Reference & Deep Dive

Biochemistry & Enzymatic Pathways
At the molecular level, Apolipoprotein C2 (ApoC2) plays an essential physiological role in lipoprotein lipase co-factor. Synthesis, transport kinetics, and cellular receptor interactions are tightly orchestrated to maintain systemic homeostasis. Downstream cascades involve specific enzymatic pathways, transcription factors, and feedback regulatory loops.
Longevity Risk Architecture & Epidemiology
Congenital or functional ApoC2 deficiency causes massive accumulation of chylomicrons and life-threatening familial chylomicronemia syndrome.
Pre-Analytical Caveats & Diagnostic Workup

Pre-Analytical Considerations:

Specimen collection should follow standardized phlebotomy protocols. Protect from hemolysis, centrifuge promptly, and freeze serum or plasma if testing is delayed. Patient should be in a resting, fasting state where indicated.

Reflexive Testing Protocol:

  • Confirmatory testing and secondary biomarker quantification for ApoC2
  • Targeted organ system imaging or functional dynamic testing related to lipoprotein lipase co-factor
  • Comprehensive baseline metabolic, renal, and inflammatory assessment (CMP, CBC, hs-CRP)
