F-NTA Antibodies — 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.
Key facts: 3 markers (CD9, CD63, CD81); 1 tetraspanin cocktail kit; 1 IgG isotype control; ready-to-use with minimal prep.
Why F-NTA reagents — 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.
The reagents — five products, one F-NTA workflow
- F-NTA CD9 (detection antibody) — high-affinity CD9 detection antibody for tetraspanin-positive EV subpopulations. CD9, 488 nm channel.
- F-NTA CD63 (detection antibody) — CD63 detection antibody for resolving the CD63-positive vesicle fraction. CD63, 561 nm channel.
- F-NTA CD81 (detection antibody) — CD81 detection antibody for the third canonical EV tetraspanin marker. CD81, 640 nm channel.
- F-NTA EV Tetraspanin Kit (detection kit) — a ready-to-use cocktail for broad tetraspanin coverage across CD9, CD63, and CD81.
- F-NTA IgG Control (control) — isotype control antibody to quantify and subtract non-specific background signal.
Why these reagents — built for clean, quantitative F-NTA
- High specificity — targeted to EV surface markers (CD9, CD63, CD81) and viral proteins.
- Ready-to-use — minimal preparation time, optimized for the ZetaView platform.
- Lyophilized — long shelf life and consistent lot-to-lot reproducibility.
- Marker-to-count — correlate surface biomarker expression directly with particle counts.
- Broad research utility — EV biology, vaccine development, and nanoparticle targeting studies.
- QC & release — supports validated assays for release testing in regulated settings.
