Good-bye Manual Liquid Handling,
Hello Automated Exosome/Extracellular Vesicles Isolation

Our fully automated technology provides solutions
for isolation of exosomes/extracellular vesicles isolation from a variety of clinical samples
with high purity and reproducibility.


Automated Exosome Isolation EViSTEP™

Exosomes/Extracellular Vesicles (EVs) are attracting much attention as they are used in a wide range of medical and healthcare fields, including diagnostic and therapeutic areas.
EViSTEP (Extracellular Vesicle Isolation and Storage Technology Platform), which is based on our core technologies of pre-treatment reagent, high quality antibodies, and a fully automated EV isolating device, has achieved stable and highly efficient isolation of EVs from a variety of samples.
Our EViSTEP instrument provides solutions for the development of your Exosome research.

What are Exosmes ?

The Exosome

Exosomes, a type of extracellular vesicles (EVs), are secreted into extracellular fluids and are found in most body fluids, including blood, urine, saliva, breast milk, and cerebrospinal fluid. A number of biologically active molecules including proteins, mRNA, miRNA, DNA and phospholipids are found in exosomes. Exosomes are thought to play key roles in cell-to-cell communication and have been associated with various disease conditions, e.g., cancer metastasis and vascularization. Thus exosome studies have great potential for the development of applications in diagnostics and novel therapies.
