Exosome Quantitation

When you need to know the amount of exosomes you’ve isolated, SBI offers a range of options that meet most quantitation needs

When you need to know the amount of exosomes you’ve isolated, SBI offers a range of options that meet most quantitation needs. For the fastest and most sensitive antibody-based quantitation, our new ExoELISA-ULTRA CD63 kit improves on our original ExoELISA Kits by providing greater sensitivity—down to 1-200 µg protein equivalent—and a fast, 4-hour workflow.

If you want speedier quantitation (20 min) that does not rely on antibody binding, the EXOCET kit provides direct measurement of the activity of a known exosomal protein, Acetylcholinesterase (AChE). FluoroCet is a >30-fold more sensitive version of EXOCET that relies upon fluorescence-based quantitation.
