  • double label in situ hybridization using biotin and digoxigenin tagged RNA Probes
    BioTechniques, 1994
    Co-Authors: Jason W Oneill, Ethan Bier
    Abstract:

    We describe a double-label in situ hybridization protocol based on the optimized synthesis of biotin-labeled RNA Probes. Biotin-labeled Probes are used in conjunction with digoxigenin-labeled Probes to simultaneously visualize two different transcripts. One transcript is hybridized with a biotin-labeled RNA Probe and visualized as a brown peroxidase reaction product, and the other transcript is hybridized with a digoxigenin-labeled RNA Probe and visualized as a blue alkaline phosphatase reaction product. We present several examples in which this double-labeling method has proven useful in determining the spatial and temporal relationships between various transcripts expressed during Drosophila embryogenesis, indicating that this method should be of general use in establishing the relationship of two independent transcription patterns.

  • salmonella detection using 16s ribosomal dna RNA Probe gold nanoparticles and lateral flow immunoassay
    Food Chemistry, 2013
    Co-Authors: Chunyan Yeung, Pohao Chen
    Abstract:

    Abstract An ultrasensitive, simple, and fast lateral flow immunoassay for Salmonella detection using gold nanoparticles conjugated with a DNA Probe, which is complementary to the 16S ribosomal RNA and DNA of Salmonella , has been developed. The detection limit is 5 fmol for the synthetic single-stranded DNA. For the Salmonella cultured samples, the nucleic acids from 10 7 bacteria were rapidly detected in 30 min. After silver enhancement, the detection limit was as low as 10 4 cells which is lower than 10 5 bacteria cells, the human infective dose of food-borne Salmonella . Furthermore, the Probes used in this study are specific to Salmonella compared to several other Enterobacteriaceae . This approach would be a useful tool for microbial detection regarding food safety or clinical diagnosis. It is also suitable for large-scale screening in developing countries because it is low-cost, sensitive, specific and convenient.
