Exosome Isolation Using ExoQuick TC from Tissue Culture Medium: A Detailed Overview
Introduction:
Exosomes are small extracellular vesicles, typically 30-150 nm in diameter, that facilitate intercellular communication by transporting biomolecules such as proteins, lipids, and nucleic acids. They play crucial roles in various physiological and pathological processes, including cancer metastasis, immune modulation, and tissue regeneration. Efficient and reliable isolation of exosomes is essential for advancing research in these areas. ExoQuick TC (10 mL) offers a robust solution for isolating exosomes from tissue culture medium, streamlining the process and maintaining the integrity of these vesicles.

Integrity: The reagent preserves the structural and functional integrity of the isolated exosomes, making them suitable for downstream applications.
Isolation Procedure
The ExoQuick TC protocol involves several key steps:
1.Sample Collection:
Collect tissue culture medium from cultured cells. Ensure the medium is free from cells and large debris by filtering it through a 0.22 µm filter.
2.Reagent Addition:
Add ExoQuick TC reagent to the filtered medium. The typical volume ratio is 1:5 (ExoQuick TC: tissue culture medium).
3.Incubation:
Incubate the mixture at 4°C for a minimum of 30 minutes to allow exosome precipitation.
4.Centrifugation:
Centrifuge the mixture at 1,500 x g for 30 minutes. This step pellets the exosomes.
5.Resuspension:
Carefully remove the supernatant and resuspend the exosome pellet in an appropriate buffer (e.g., PBS) for subsequent analysis.
