  • CD133+), but are rarely codetected with the neural stem dents, very few human-specific NSC markers have been cell (NSC) marker CD15. (lu.se)
  • After success with that construct, they next looked for other exons that might be more sensitive to LMI070 by treating cultured cells with the drug and using high-throughput RNA sequencing to discover which genes were most actively expressed by the treatment. (scienceboard.net)
  • As a result, VDJ recombination, HLA restriction, and antigen exposure collectively contribute to a largely private TCRβ repertoire. (biorxiv.org)

  • Using Droplet Digital PCR systems from Bio-Rad Laboratories, "we've developed simple singleplex assays to help detect low levels of transduced human cells in mouse tissues, duplex assays for biodistribution studies of CAR T-cell and [T-cell receptor] studies, assays for pharmacokinetic studies, and DNA and RNA analysis for prophylactic immune mitigation studies," Moritz said.
