Capture primers and capture sequence linked solid supports for molecular diagnostic tests

The present invention provides systems, methods, and compositions for performing molecular tests. In particular, the present invention provides methods, compositions and systems for generating target sequence-linked solid supports (e.g., beads) using a solid support linked to a plurality of capture sequences and capture primers composed of a 3′ target-specific portion and a 5′ capture sequence portion. In certain embodiments, the target sequence linked solid support is used in sequencing methods (e.g., pyrosequencing, zero-mode waveguide type sequencing, nanopore sequencing, etc.) to determine the sequence of the target sequence (e.g., in order to detect the identity of a target nucleic acid in sample).

Molecular Diagnostic Test for Cancer

Methods and compositions are provided for the identification of a molecular diagnostic test for cancer. The test identifies cancer subtypes that are responsive to anti-angiogenesis therapeutics and enables classification of a patient within this subtype. The present invention can be used to determine whether patients with cancer are clinically responsive or non-responsive to a therapeutic regimen prior to administration of any anti-angiogenic agent. This test may be used in different cancer types and with different drugs that directly or indirectly affect angiogenesis or angiogenesis signalling. In addition, the present invention may be used as a prognostic indicator for certain cancer types. In particular, the present invention is directed to the use of certain combinations of predictive markers, wherein the expression of the predictive markers correlates with responsiveness or non-responsiveness to a therapeutic regimen.

Portable molecular diagnostic device and methods for the detection of target viruses

A method includes coupling a molecular diagnostic test device to a power source. A biological sample is conveyed into a sample preparation module. The device is then actuated by only a single action to cause the device to perform the following functions without further user action. First, the device heats the sample via a heater of the sample preparation module to lyse a portion of the sample. Second, the device conveys the lysed sample to an amplification module and heats the sample within a reaction volume of the amplification module to amplify a nucleic acid thereby producing an output solution containing a target amplicon. The device then reacts, within a detection module, each of (i) the output solution and (ii) a reagent formulated to produce a signal that indicates a presence of thetarget amplicon within the output solution. A result associated with the signal is then read.
