Description
Easily isolate highly purified human CD9+ extracellular vesicles (EVs) from plasma, serum, cell culture conditioned medium, and urine samples, using immunomagnetic positive selection, with the EasySep™ Human Extracellular Vesicle (CD9) Positive Selection Kit. Widely used in published research for more than 20 years, EasySep™ combines the specificity of monoclonal antibodies with the simplicity of a column-free magnetic system.
In this EasySep™ positive selection procedure, desired EVs are labeled with antibody complexes recognizing the specific tetraspanin marker CD9 and magnetic particles. Labeled EVs are separated using an EasySep™ magnet and by simply pouring or pipetting off the unwanted biofluid components. The EVs of interest remain in the tube. Following magnetic EV isolation in less than 30 minutes, the desired CD9+ EVs are ready for downstream applications such as DNA/RNA extraction, western blot, or mass spectrometry. This method yields EV preparations with low levels of contaminating proteins such as apolipoproteins and albumin, helping to ensure cleaner samples for sensitive downstream analyses.
