Extracellular Vesicle Analysis Assays We lived with inaccurate vesicle concentration estimates and limited sensitivity. Existing assays restricted our efforts to characterize vesicles by size and cargo and counted debris. So we started over and developed a robust assay that uses widely available instruments.
Consistent Vesicle Analysis Techniques

Consistent, well-defined study of vesicles

That’s what this field needs. Whether you call them exosomes, microvesicles, or EVs, you know everyone studying these tiny particles suffers from inconsistent, poorly characterized methods. Our standards, reference samples, and assays are over-engineered to ensure measurements across samples and across vesicle research labs can be directly compared.

Standards and Reference Materials

To support appropriately run analyses and generation of reproducible data that can be compared across labs and time, we provide multiple standards for incorporation into your EV characterization workflow. Each standard is designed an manufactured to be relevant to EVs in size and fluorescence intensity. They are validated using multiple orthogonal methods consistent with the latest guidelines for vesicle analysis. Measurements of each lot include concentration, size, surface markers or fluorescence intensity, and other product specific parameters to ensure reliable performance.
