Abstract: The methods and reagents are provided for barcoding and analysis of DNA samples using partition (e.g., droplet) technology while avoiding performing amplification in droplets.
Abstract: The technology as disclosed herein relates to methods, compositions and kits for multiplex measuring levels of expression of target RNA species (e.g., mRNA and non-coding RNAs) in single, living cells. Aspects of the invention relate to, in part, a duplex-binding protein which is labeled with a FRET dye, and a RNA-binding probe, which comprises a spectrally paired FRET dye and specifically hybridizes to a target RNA. When the RNA-binding probe binds to a target RNA, a duplex is formed, which is allows binding of the duplex-binding protein bringing the two FRET dyes into close proximity and allowing fluorescence resonance energy transfer (FRET) reaction and a detectable change in fluorescence, which determines the amount of target RNA species in the living cell. Aspects of the invention also include, kits, vectors and polynucleic acid sequences of the duplex-binding protein and RNA-binding probes disclosed herein, and cell and cell lines comprising the same.
Abstract: Provided herein are methods and kits for detecting the presence of DNA mutations in the KRAS, BRAF, CTNNB1, and APC genes. The methods and kits employ microcarriers, each with a probe specific for a DNA mutation in the KRAS, BRAF, CTNNB1, or APC gene and an identifier unique to the probe sequence. Upon isolation and amplification of DNA from a sample, hybridization of amplified DNA with a probe, specific for a DNA mutation, that is coupled to a microcarrier indicates the presence of the DNA mutation in the sample. Since each microcarrier can be identified through detection of the identifier, multiplex screening assays for multiple mutations in each of the KRAS, BRAF, CTNNB1, and APC genes are provided.
