  • Patent number: 11603565
    Abstract: The invention is a method of identifying a cognate antigen for a T-cell receptor using neoantigens from a patient's tumor cells combined with the patient's T-cells and using cell sorting, genome sequencing, expressing TCR genes, presenting tumor neoantigens on MHC complex and uniquely barcoding the T-cells where TCR recognition occurs to tag all components of the TCR recognition complex.

  • Publication number: 20220064733
    Abstract: Disclosed herein is a method of deriving a plurality of genetic variants from a homogenized input sample. Also disclosed herein are methods of identifying a plurality of genetic variants in a sample comprising: homogenizing one or more input samples to provide a homogenized sample; preparing genomic material isolated from the homogenized input sample for sequencing; and identifying the plurality of genetic variants within sequencing data derived after sequencing the prepared genomic material.

  • Publication number: 20170212122
    Abstract: Disclosed herein are multiplex methods for co-detecting a B cell marker, TP53 nucleic acid, and Chromosome 17 centromere DNA in a single sample. Samples stained for the B cell marker (e.g., CD79a protein), TP53 nucleic acid, and Chromosome 17 centromere DNA may allow for the identification of the subtype of chronic lymphocytic leukemia (CLL) with the 17p deletion. The methods feature staining the B cell marker (e.g., CD79a) a first distinct color, TP53 in a second distinct color, and chromosome 17 centromere DNA in a third distinct color. Further disclosed are nucleic acid probes specific for 19q12, INSR, ATM, DLEU2, TP53, and 13q12.
