Insulin Release Assay Service
Creative Biolabs delivers specific, actionable functional data essential for advancing compounds targeting glucose homeostasis. We move beyond simple concentration measurements to provide deep pharmacological characterization of your drug candidates, ensuring every lead is rigorously vetted for in vivo potential. Our comprehensive services include glucose-induced insulin release assays, glucose uptake assays, and receptor binding and activation studies. These capabilities provide a holistic understanding of your compound's mechanism of action, potency, and selectivity, enabling informed decision-making and accelerating your drug development pipeline.
Introduction: Addressing the Global Metabolic Crisis
Dysregulation of glucose homeostasis, primarily due to compromised insulin function, is a major global health challenge, with type 2 diabetes mellitus (T2DM) reaching epidemic proportions. The accurate, sensitive, and reliable quantification of insulin release in vitro is an absolute scientific imperative for drug developers targeting pancreatic β-cells. The Insulin Release Assay is the gold standard functional assay for quantifying β-cell secretory capacity, vital for developing new drugs against T2DM, where insufficient glucose-stimulated insulin secretion (GSIS) is the core pathology.
A Robust and Standardized Protocol for Efficacy Screening
The reliability of any functional assay is dictated by its model system and rigorous protocol. Our cell-based insulin release assay is meticulously standardized to provide biologically relevant and consistent data.
| Assay Parameter | Specification | Purpose |
|---|---|---|
| Cell Model | HIT-T15 β-cells (Hamster pancreas) | Well-characterized, insulin-secreting line ensuring physiological relevance. |
| Detection Method | Time-resolved fluorescence resonance energy transfer (TR-FRET) | High sensitivity and low background interference. |
| Functional Mode | Agonist/Antagonist screening | Comprehensive evaluation of compound activity. |
| Control Activator | D-Glucose (10 mM or 100 mM) | Positive control for physiological insulin release stimulation. |
| Control Inhibitor | Somatostatin-14 | Negative control for demonstrating assay inhibition. |

This comprehensive workflow is designed for transparency and is suitable for visualization as a flowchart, making it very clear to potential clients what is involved and what high-quality outputs to expect at each stage.
Publication
This study introduces a rapid, homogenous time-resolved fluorescence assay for insulin detection. Designed to overcome the cost and throughput limitations of ELISAs and RIAs, this homogenous, mix-and-read method is significantly faster and cheaper. The assay was effectively validated by measuring GSIS in INS-1E cells and mouse pancreatic islets. Its utility was further demonstrated by confirming dopamine and the anti-diabetic drug bromocriptine as potent inhibitors of GSIS, establishing it as a robust tool for diabetes research and drug screening.

FAQs
Why should I choose the TR-FRET assay over a conventional ELISA for my high-throughput screen?
Our TR-FRET assay is fundamentally designed for optimal high-throughput and reliability. This dramatically minimizes background noise from biological matrices or compounds, delivering a superior Z'-factor and ensuring that your drug discovery is based on the most robust, cleanest data possible.
Can your assay service handle my unique, patient-derived β-cell model?
Absolutely. Creative Biolabs routinely adapts its protocol for various cell models, including human induced pluripotent stem cell (hPSC)-derived β-cells and genetically modified lines that express specific transcriptional defects.
We are looking to screen an antagonist. What precautions are necessary for this type of compound in your assay?
A key precaution we manage is cytotoxicity; we run parallel β-cell viability assays to ensure any observed reduction in insulin secretion is due to specific antagonism, not general cellular toxicity. We welcome your antagonist libraries and are ready to design a targeted screen.
