Droplet Digital PCR is the perfect tool to detect gene-modified cells in different body fluids
Immunotherapy with CD19-specific CAR-T cells has shown excellent efficacy in late-stage relapsed/refractory B-cell cancers. In-vivo expansion and persistence of CAR-T cells after infusion are important response and toxicity determining variables, but diagnostic tools are largely missing.
Droplet digital PCR (ddPCR) is characterised by excellent sensitivity, specificity and reproducibility. Dr Fehse and his team have cloned and sequenced complete cDNAs of both vector constructs. They have designed different combinations of primers and dual-labelled hydrolysis probes and tested them on CAR-T cells, post-infusion samples, and controls in duplex reactions with reference genes.
They have developed and applied novel ddPCR assays for monitoring of Axi-cel and Tisa-cel CAR-T cells in vivo.
Join us for our live webinar where Dr Fehse talks us through his research about how ddPCR is excellently suited as a diagnostic tool to monitor infused cells in real-time in different body fluids.
