Arrays of nanoscale electronic elements comprising two electrodes separated by an insulating layer are used to provide sequence information about a template nucleic acid in a polymerase-template complex bound proximate to the insulating region. A sequencing reaction mixture comprising nucleotide analogs having impedance labels is introduced to the array of nanoscale electronic elements under conditions of polymerase mediated nucleic acid synthesis. The time sequence of incorporation of nucleotide analogs is determined by identifying the types of labels of the nucleotide analogs that are incorporated into the growing strand using measured impedance.Type: ApplicationFiled: October 30, 2019Publication date: April 2, 2020Inventors: Stephen Turner, Jeremiah Hanes, Keith Bjornson

Publication number: 20200102614Abstract: The present application relates to a detection kit for genotypes capable of confirming cross contamination that may occur in a banking process of a patient-derived xenograft model or cell-derived xenograft model and a method for determining cross contamination using the same. According to the present disclosure, it is possible to determine all of cross contamination of mouse related genes, have high detection sensitivity and specificity to be close to 100%, rapidly examine the contamination, and be very useful in predicting mouse contamination. Therefore, according to the present disclosure, cross contamination of genes related with the human and the mouse is predicted in advance to be applied to evaluation of anticancer drug efficacy using a patient-derived xenograft model or cell-derived xenograft model and contribute to cell banks using the patient-derived xenograft model or cell-derived xenograft model, and as a result, the present disclosure is very useful in a medical industry.Type: ApplicationFiled: October 29, 2019Publication date: April 2, 2020Inventors: Yoon La CHOI, Yun Su LEE

Publication number: 20200102615Abstract: The present invention provides a method of screening a mammal for the onset or predisposition to the onset of a neuropsychiatric disorder. More particularly, the present invention provides a method of screening a mammal for the onset or predisposition to the onset of schizophrenia by screening for a decrease in the functional level of protein 14-3-3?. In a related aspect, the present invention also provides a means of monitoring a patient diagnosed with a neuropsychiatric disorder, such as schizophrenia, by screening for changes to functional levels of protein 14-3-3?. This may be useful, for example, in the context of evaluating the effectiveness of a prophylactic or therapeutic treatment regime or otherwise monitoring the impact of physiological or metabolic changes which may occur in a patient.Type: ApplicationFiled: October 21, 2019Publication date: April 2, 2020Inventors: Quenten Philip Schwarz, Angel Francisco Lopez
