Human PD-L1 positive exosome (CD9) ELISA kit
PD-L1 positive exosomes can be directly quantified from blood samples and cell culture supernatants using the ELISA method!
This product is a sandwich ELISA kit that utilizes high-performance antibodies against CD9, an exosome marker, and PD-L1, an immune checkpoint-related molecule, to detect PD-L1 molecules expressed on the surface of exosomes secreted by cells in human blood and cell culture supernatants. PD-L1 is also expressed on exosomes, adopting the same topology as PD-L1 on the surface of cancer cells, with the extracellular domain exposed on the surface of the exosomes. Features: - Highly sensitive detection of human PD-L1 positive exosomes using the ELISA method (detection sensitivity: 0.05 ng/mL) - Direct quantification of PD-L1 positive exosomes contained in human blood samples and cell culture supernatants - No special equipment is required; measurements can be taken with a standard plate reader - Instead of using exosomes themselves, which lack storage stability as standard reagents, stability and reproducibility are ensured by using PD-L1/CD9 fusion protein (standard protein) - Relative quantification of each sample is possible by reading a standard curve using PD-L1/CD9 fusion protein (standard protein)
