Angiopoietin-like protein 6 (ANGPTL6), also known as angiopoietin-related growth factor (AGF) or ARP5, is a secreted glycoprotein involved in regulating angiogenesis, lipid metabolism, glucose homeostasis, and energy balance. Unlike classical angiopoietins, ANGPTL6 does not bind Tie receptors but exerts distinct biological functions that influence metabolic health. Elevated serum levels of ANGPTL6 have been associated with obesity, type 2 diabetes mellitus (T2DM), metabolic syndrome, and certain cancers, such as hepatocellular carcinoma (HCC), highlighting its potential as a biomarker and therapeutic target.
Performance Characteristics
- High Sensitivity
- Detection Range: Varies by species and kit.
- Precision: Intra-assay coefficient of variation (CV) typically <10%, inter-assay CV <12%, ensuring reproducibility.
- Sample Compatibility: Suitable for serum, plasma (EDTA, heparin), tissue homogenates, and cell culture supernatants.
- Assay Time: Generally completed within 2 to 4.5 hours.
Applications
- Metabolic Disease Research: Quantification of ANGPTL6 levels in obesity, T2DM, and metabolic syndrome studies to elucidate its role in insulin sensitivity and energy metabolism.
- Cancer Biomarker Studies: Measurement of serum ANGPTL6 as a potential biomarker for early diagnosis of hepatocellular carcinoma, especially in HBV-related cases where ANGPTL6 complements alpha-fetoprotein (AFP) testing.
- Pharmacological Screening: Evaluation of therapeutic interventions targeting ANGPTL6 pathways.
- Basic Science: Investigation of ANGPTL6 function in angiogenesis, lipid metabolism, and systemic energy homeostasis.
ANGPTL6 assay kits provide robust, sensitive, and specific tools for the quantitative measurement of ANGPTL6 protein in diverse biological samples. These kits support a broad spectrum of research applications, from metabolic disease and cancer biomarker studies to fundamental investigations of angiogenesis and energy metabolism. Their availability in formats tailored to human, rat, and mouse samples enhances their utility in translational and preclinical research, contributing to the understanding of ANGPTL6 biology and its potential as a therapeutic target.
