Obesity Serum
Obesity Serum from IRB-consented donors with clinically confirmed obesity, frozen within 24 hours. Suitable for adipokine profiling (leptin, adiponectin), lipid and lipoprotein panels, insulin resistance biomarkers and metabolic inflammation research. BMI class and comorbidity stratification available.
Obesity Serum for Metabolic Disease and Metabolic Inflammation Research
Our Obesity Serum is sourced from IRB-consented donors clinically diagnosed with obesity. Each sample is processed and frozen within 24 hours of collection to ensure consistency and high quality for metabolic, endocrine and cardiometabolic research. Obesity is a chronic metabolic condition in which excess and dysfunctional adipose tissue alters systemic endocrine and inflammatory signalling — changes that are directly measurable in circulation.
Adipose Endocrine Signalling and Metabolic Inflammation
- Adipose tissue is an endocrine organ. With expansion it alters secretion of adipokines including leptin and adiponectin, and these shifts are reflected in circulating concentrations measurable by serum immunoassay.
- Expanded adipose tissue in obesity is associated with low-grade chronic inflammation and macrophage infiltration, with corresponding changes in circulating inflammatory mediators such as CRP, IL-6 and TNF-related analytes. This is metabolic inflammation, not autoimmunity.
- Insulin resistance commonly accompanies obesity, and serum supports fasting glucose, insulin and derived insulin-sensitivity index work alongside HbA1c-adjacent metabolic characterisation.
- Dyslipidaemia in obesity typically involves raised triglycerides and altered lipoprotein composition, making serum the standard matrix for lipid panels and lipidomic profiling.
- Serum is acellular and well suited to hormone and adipokine immunoassay, clinical chemistry, proteomics, metabolomics and lipidomics; no cell-based assays are performed on this matrix.
- Incretin and appetite-regulatory biology is a major therapeutic focus in obesity, and characterised donor serum supports assay development and biomarker validation in that space.
