    Northern Blot with IR Fluorescent Probes: Strategies for Probe Preparation
    Authors:  Christopher Fields, Peike Sheng, Bret Miller, Tianqi Wei and Mingyi Xie, date: 04/20/2019, view: 5352, Q&A: 1
    [Abstract] Northern blot is a molecular biology technique that can detect, quantify, and determine the molecular weight of RNA. Recently, we published a protocol utilizing near-infrared (IR) fluorescent probes in Northern blot (irNorthern). Our method is as sensitive as other non-radioactive methods but is more straightforward and versatile. Additionally, we ...
    In situ Hybridization (ISH) and Quantum Dots (QD) of miRNAs
    Authors:  Sajni Josson, Murali Gururajan and Leland W.K. Chung, date: 02/20/2017, view: 7508, Q&A: 0
    [Abstract] miRNA are short non-coding RNA which inhibit translation of mRNA. miRNA regulate several cellular processes. Certain miRNA are known to induce oncogenesis. miRNA can be measured by real-time PCR and be imaged using a combination of in situ hybridization (ISH) and quantum dots (QD). The advantage of using quantum dots is that several miRNA ...
    miRNA Characterization from the Extracellular Vesicles
    Authors:  Sajni Josson, Murali Gururajan and Leland W.K. Chung, date: 02/20/2017, view: 5361, Q&A: 0
    [Abstract] Cancer cells and cancer associated stromal cells co-evolve secrete extracellular vesicles to the surrounding regions and regulate several processes involved in cancer metastasis. miRNAs have been known to be mediators of cancer progression and metastasis. miRNAs consist of short noncoding RNA. miRNAs are stable in extracellular fluids such as ...
    miRNA Tagging and Affinity-purification (miRAP)
    Author:  Miao He, date: 10/05/2012, view: 10173, Q&A: 1
    [Abstract] MicroRNAs(miRNAs) are a group of endogenously expressed 20~23 nt small noncoding RNAs, which can directly regulate mRNA stability or translation in a sequence specific manner by incomplete base pairing at the 3’UTR of target mRNA, or indirectly affect transcriptional network by regulating transcription factors. As key regulators of gene ...
