Exosomes are 30-150 nm tiny vesicles that are available to isolate and purify from plasma and other body fluids and regarded as the useful biomarker for therapeutic and diagnostic application. With years of experiences in exosome preparation, Creative Biolabs provides high-quality exosome purification services by using ultracentrifugation and microfiltration from both plasma and other body fluids with decreased co-purification of non-exosomal blood proteins, thus increasing the purification and integrity of exosomes.
