Attached is our latest video demonstrating the versatility of S-TECH for the isolation of subcellular particles from human serum. Our EV isolation membranes use geometrically precise track-etched pores in thin film polycarbonate, a configuration which eliminates the entrapment of subcellular particles which occurs with fibre or mesh type filtration systems. In the video we demonstrate how easy S-TECH is to use as a single device for the isolation, purification, concentration and buffer exchange of subcellular particles from 125ul of serum (250ul total volume diluted in PBS 1:1). We also demonstrate the particle size distribution by tunable resistive pulse sensing (TRPS) and the efficient protein purification that occurs during the S-TECH processing of the serum sample.
S-TECH are sold in boxes of 32 units worldwide.
