Overview:
A better way to isolate exosomes

“We therefore pursued the ExoQuick
?
method for further study, as these samples required much less sample input, a key benefit when working with clinical samples and mouse models

’s ExoQuick, original formulation, enables high-throughput, quantitative isolation of exosomes from low volumes (as little as 100 ?l) of serum, plasma, or ascites fluid. Compat

ExoQuick’s fast, ultracentrifugation-free method:


Saves time and labor

Is easily scalable

Conserves precious sample

Delivers high yields of functional, high quality exosomes

Can be used to isolate exosomes for a wide range of downstream applications, including

ExoQuick is a proprietary polymer that gently precipitates exosomes. First, pre-clear your samples of cells and cellular debris, and then simply add the appropriate amount of ExoQuick to your cleared biofluid, refrigerate, and centrifuge (see the product manual for protocol details). Your exosomes will be in the pellet, ready for res

In electron microscopy studies, exosomes isolated with ExoQuick appear similar to exosomes isolated using ultracentrifugation
1-2
, and these exosomes are also active in numerous functional assays
1-3
.

Exosomes isolated with ExoQuick can be used for all types of protein profiling and protein characterization studies, such as mass spectrometry, Western blotting,
ELISA
, and more. Higher protein yields are achieved by ExoQuick purification than by chromatography, DynaBeads, or ultracentrifugation.

Exosomes isolated with ExoQuick also provide excellent samples for studying exosome-associated nucleic acids such as microRNAs, siRNAs, and even mRNA. Quantitative analytical techniques such as qPCR, microarray studies, and next-generation sequencing are all compat

e with nucleic acids isolated from ExoQuick-purified exosomes.

Backed by a growing number of publications, ExoQuick is often the best option for researchers working with low sample volumes, such as clinical research samples or small animal models.

ExoQuick exosome isolation methods are patented technologies

How It Works:
High-throughput, quantitative exosome recovery

ExoQuick can be used to purify exosomes from plasma
1
, serum
2
, and malignant ascites
3
. With a simple workflow involving minimal hands-on time and low input sample volume requirements, ExoQuick is an excellent option for researchers who need to purify multiple exosome samples and/or samples from small animal models or clinical research samples.


To isolate exosomes from cleared serum, plasma, or ascites fluid, simply:
Add an appropriate volume of ExoQuick to as little as 100 ?l sample Incubate for at least one hour at 4°C Isolate exosomes with a 30-minute low-speed spin (1500
g
).
Isolated exosomes can be found in the pellet and res
USP
ended in an appropriate solution.


You can verify the presence of exosomes with a number of different methods, including Western blotting for general exosome
Marker
s (CD63, CD9, CD81, and HSP70), NanoSight analysis, or EM (learn about different ways to detect exosomes and more in our Exosome Basics Guide).

The Bottom Line
With ExoQuick, you can obtain high-quality exosomes from most biofluids using a protocol that can easily be performed on multiple samples and requires very low volumes of input sample.
