Protocols

CD9 Immunostaining in vFC™

vFC™ (#CBS4) is an assay that enables specific detection and characterization of individual extracellular vesicles such as exosomes and microvesicles on commercially available flow cytometers. This protocol makes use of vFC™ to provide a standardized means of analyzing individual vesicles to measure size, concentration, and CD41 expression simultaneously. Because vFC™ triggers on vesicles, pairing antibody staining with vFC™ enables a highly-reproducible, no-wash assay. In this protocol, vesicles will be stained using our vTag™ Anti-Human CD41 Antibody. See protocol 2 in the vFC™ kit handbook for additional considerations and full protocol details.Procedure

We recommend using vTag™ Antibodies with the vFC™ Assay. Full, detailed protocols are available on the product page.
  1. Dilute sample containing EVs to approximately 5×106 extracellular vesicles per µl. To empirically determine vesicle concentration and identify an optimal pre-stain dilution, see supporting protocols included in the vFC™ kit.
  2. Prepare a working concentration of vFRed™ Red (5 µl per well) according to kit instructions
  3. In duplicate, in the included 96 well plate, add 35 µl of dilution buffer, 5µl of vFRed™ Red, 5 µl of vTag™ anti-human CD41 antibody, and 5 µl of EV sample.
  4. Incubate in the dark for 1hr.
  5. Perform serial dilution of the samples as described in the assay handbook. Briefly, samples are to be diluted from between 1:100 to 1:1000 from staining concentration depending upon the flow cytometer being used.
  6. Analyze the diluted sample of labeled EVs on a qualified flow cytometer.

CD41 Background Information

CD41 (also known as Integrin alpha IIb or ITGA2B) is a glycoprotein that is a key component of the integrin complex αIIbβ3, also known as GPIIbIIIa. It is predominantly expressed on platelets and megakaryocytes. CD41 plays a crucial role in platelet aggregation and thrombosis by binding to fibrinogen and other adhesive proteins, facilitating platelet adhesion and clot formation. This integrin complex is essential for normal blood clotting and hemostasis. (see the data by vesicle origin resource for more info).
