Turn a particle count into a specific one.
Fluorescence-NTA earns its specificity from the label. These antibodies are optimized for the ZetaView® platform — ready-to-use, lyophilized for shelf stability, and targeted to the EV surface markers that tell your vesicles apart from everything else in the sample.
Specificity is a reagent decision.
Light scatter counts every particle in a suspension; fluorescence counts only the ones your antibody binds. The quality of that distinction — the gap between total and specific — depends entirely on the label: its affinity, its fluorophore, and the control you run alongside it.
Each antibody here is high-affinity and lyophilized for lot-to-lot consistency, with an IgG isotype control so you can measure and subtract non-specific background instead of guessing at it.
Optimized for fluorescence NTA.
Our F-NTA antibodies are high-affinity, ready-to-use reagents specifically designed for tetraspanin detection. They bring quantitative specificity to your extracellular vesicle tracking.
Pick a reagent, see what lights up
The same EV field, read with different labels. A single-marker antibody illuminates one subpopulation; the tetraspanin kit captures the union of all three; the IgG control shows the non-specific background that every specific count must be measured against.
Switch to the IgG control — the field nearly goes dark. That residual signal is your background, and it is exactly why an isotype control belongs in the experiment.
