The TRIFic™ exosome detection assay is an ELISA-like assay in the sense that it is an antibody sandwich-based assay for the detection of exosome particles. However, there are some significant differences. Unlike a standard ELISA assay, there is no enzymatic reaction. Rather, the exosome target is detected directly with a Europium labelled-antibody, constituting a time-resolved immunofluorescence assay.
The TRIFic™ exosome assays provide clear and consistent data quickly from purified or unpurified samples in a convenient 96-well format. The kit is available for marker proteins CD9, CD63, and CD81.
NTA size profiling service
Nanoparticle tracking analysis (NTA) is a technique used for the simultaneous measurement and analysis of the size and concentration of single nanoparticles with high precision, accuracy, and reproducibility.
The NTA service is performed in our laboratories by a team of experienced scientists. All data and selected parameters are provided as a final report. We use the ZetaView® nanoparticle analysis instrument.
Exosome validated antibodies
The exosome marker antibodies have been validated against exosome-associated antigens CD9, CD63, and CD81 to characterize and/or quantify exosomes in cell culture media and biological fluids. The high-quality exosome validated antibodies have been specifically tested for western blotting, the most common method to assess the presence of proteins in EV samples.
