Obesity & Metabolic Disease Research Tools

Obesity is the second leading cause of preventable death in the United States and is associated with type 2 diabetes, cardiovascular disease, MASLD, and cancer. Cayman provides biochemicals, peptides, assay kits, and reagent sets to support research into the biological mechanisms driving these conditions.

Receptor Pharmacology

GLP-1 Receptor Agonists

Originally developed to treat type 2 diabetes, GLP-1 receptor agonists have found new therapeutic utility for obesity. GLP-1R is expressed in pancreatic beta cells, adipocytes, the brain, kidney, stomach, and heart. GLP-1 released from intestinal L-cells stimulates insulin biosynthesis, reduces glucagon secretion, and slows gastrointestinal motility to increase satiety. Cayman offers GLP-1R agonists for research use only.

Dual & Multi-Receptor Agonists

GLP-1 and GIP receptor agonists synergize, providing greater benefits than GLP-1 receptor agonists alone. These dual agonists, known as twincretins, also appear to reduce side effects through their complementary mechanisms of action. Glucagon receptor co-agonism further promotes satiety and increases energy expenditure through thermogenesis. Cayman offers a full range for research use only.

GLP-1, GIP, & GLP-2 Receptor Assays

Cayman offers cell-based reporter assay kits for functional characterization of GLP-1R, GIPR, and GLP-2R, enabling agonist potency determination, inhibitor screening, and comparative pharmacology across incretin and related receptor systems.

Calcitonin & Amylin Receptors

The calcitonin receptor (CTR) heterodimerizes with RAMP1, RAMP2, or RAMP3 to form the AMY1, AMY2, and AMY3 receptors, which regulate fat utilization, food intake, and glucose control. Amylin, co-secreted with insulin from pancreatic beta cells, induces satiety through homeostatic and hedonic regions of the brain via pathways complementary to GLP-1 with an additive effect on appetite reduction when combined. Cagrilintide, a long-acting amylin and calcitonin receptor agonist, is currently in phase 3 trials as CagriSema in combination with semaglutide.

DPP-IV Inhibitors & Assay

DPP-IV rapidly degrades incretins such as GLP-1, limiting their biological activity. DPP-IV inhibitors block this degradation, preserving native incretin bioactivity and enabling studies of endogenous GLP-1 physiology.

Endogenous Peptides & Hormones

GLP-1 Peptide Forms

GLP-1 is an incretin hormone released from the gut after eating. It stimulates insulin secretion, reduces post-meal blood glucose, slows gastric emptying, decreases gut motility, and reduces food intake and appetite. Cayman offers the endogenous GLP-1 peptides listed below, as well as a broader selection of exogenous GLP-1 peptides and analogs.

Peptide Hormones in Metabolism

Peptide hormones regulate energy metabolism, food intake, and satiety through distinct pathways. Raptin, a recently identified sleep-inducible hypothalamic hormone, suppresses appetite and gastric emptying through GRM3 signaling, extending the biology of body weight regulation beyond the gut.

Metabolic Signaling Assay Kits

Insulin Resistance & Glucose Homeostasis

Insulin and glucagon regulate blood glucose through opposing actions. Disruptions in glucose uptake and insulin signaling are central to the pathogenesis of type 2 diabetes and obesity.

PPAR Transcription Factor Assays

Peroxisome proliferator-activated receptors (PPARs) are nuclear transcription factors that function as master regulators of carbohydrate and lipid metabolism. PPARα regulates fatty acid oxidation in the liver; PPARγ controls adipogenesis and insulin sensitivity; PPARδ modulates energy expenditure and lipid catabolism in muscle and adipose tissue. PPAR dysregulation is directly implicated in insulin resistance, dyslipidemia, and hepatic steatosis in obesity. Cayman offers 96-well transcription factor assay kits for quantifying PPAR DNA binding activity across all three subtypes.
