The MagIso™ CD81 Exosome Isolation Kit, 32 Samples (# WHK-S017) enables the high-throughput, plate-based immunopurification of exosomes directly from serum or from concentrated exosomes from media. The magnetic particles are provided pre-coupled with CD81 antibody for selective isolation of exosomes from 32 samples simultaneously. The kit contains all of the reagents for 32 samples. Exosomes in serum or plasma samples can be immunopurified directly by adding to the IP magnetic particles. We recommend concentrating exosomes first from media, urine and CSF before immunopurifcation. Choose from exosome IP antibodies for CD81 surface markers. The exosome are immunopurified and eluted intact-allowing for downstream functional studies as well as for exoRNA and protein biomarker analyses.
