The F-NTA CD81 Detection Antibody is a monoclonal fluorescent antibody developed for detection of CD81-positive extracellular vesicles via F-NTA. Offered in multiple excitation conjugates (488 nm, 520 nm, 640 nm), it enables high-fidelity EV phenotyping.
KEY APPLICATIONS
Selective detection of CD81+ EV fractions
Multiplex EV phenotyping alongside CD9 / CD63
Monitoring changes in EV marker composition under treatments
Quality control / validation of EV isolations
Co-localization of CD81 with other surface markers
Why F-NTA CD81 Detection Antibody?
Strong specificity and affinity reduce background noise
Fluorophore conjugates optimized for standard F-NTA lighting setups
Delivered with preset instrument settings and staining protocols
Compatible with multiplex panels; stable over measurement period
Useful in combination with other tetraspanin reagents
Applications
Measuring CD81+ EV levels in patient samples (blood, urine)
EV subpopulation differentiation (e.g. CD81+/CD9+ etc.)
Dynamics of EV marker expression in cell culture under stress or stimulus
