Capturem extracellular vesicle (EV) isolation kits are a complete solution for simple isolation of EVs in <30 min. These columns use a lectin-based binding compound to selectively isolate EVs from various biofluids. Ultracentrifugation is slow, damages EVs, and pulls down contaminants, confounding results. Other methods, like precipitation, are inconsistent, with low yield and purity. Our kits yield pure, intact EVs for downstream analyses, advancing diagnostic research and biomarker discovery.
