With a 4-hour total assay time, this sensitive ELISA-based assay speeds quantitation of exosomes from most biofluids

 

• Sensitive—detect as little as 1 µg protein equivalent
• Fast—complete in less than 4-hours—no more overnight incubation
• Flexible—compatible with all major exosome isolation methods (e.g. ExoQuick®, ultracentrifugation, ultrafiltration, and immunoaffinity capture) from human samples
• Quantitative—calibrated internal standards enable quantitation of exosomes carrying CD63
• Sample-saving—requires significantly less sample than our standard ExoELISA Kit, leaving more for other downstream applications

Overview

Delivering ELISA-based exosome quantitation ULTRA fast

Improving on our popular ExoELISA^™ Kits, the ExoELISA-ULTRA CD63 Kit increases the sensitivity of exosome detection—as low as 1 µg protein equivalent—while shortening the total assay time to only 4 hours.

Currently configured for detection of CD63, a widely recognized and popular exosomal marker¹, ExoELISA-ULTRA CD63 is based on an ultra-sensitive, direct capture, colorimetric ELISA assay that is compatible with nearly all biofluids. The ExoELISA-ULTRA CD63 Kit comes with an internal standard calibrated to exosomes from a range of biofluids. Calibration is achieved by NanoSight analysis and enables quantitation of exosomes carrying CD63 in your target samples. One ExoELISA-ULTRA CD63 Kit contains all of the necessary reagents (including assay plate) to perform up to 96 reactions.

• Sensitive—detect as little as 1 µg protein equivalent
• Fast—complete in less than 4-hours—no more overnight incubation
• Flexible—compatible with all major exosome isolation methods (e.g. ExoQuick^®, ultracentrifugation, ultrafiltration, and immunoaffinity capture) from human samples
• Quantitative—calibrated internal standards enable quantitation of exosomes carrying CD63
• Sample-saving—requires significantly less sample than our standard ExoELISA Kit, leaving more for other downstream applications
