Applications of Non-radioactive Probes in DNA Hybridization


Book Description

Hybridized DNA can be visualized as an intense bluish-purple band.By using this BluGene non-radioactive probe, we were able to map the cI gene on the lambda DNA genome. Results and the application of the system will be presented and discussed. The second system is PhotoGene Nucleic Acid Detection System. When the membrane is incubated with a substrate for alkaline phosphatase that luminesces when dephosphorylated, dark bands can be visualized by using a X-ray film. By using this method, we have labelled a yeast DNA fragment of 6.6 kb as a probe and hybridized with the restriction endonuclease digested yeast genomic DNA after Southeast transfer. DNA was visualized as dark bands in X-ray film. [Authors' abstract].




Nonisotopic DNA Probe Techniques


Book Description

Recently many nonisotopic methods of probing specific DNA sequences have been developed as replacements for radioactive labels, such as 32phosphorous and 125iodine. This book brings all of these new methods together in one convenient, easily accessible source. It enables researchers to select the nonisotopic method best suited to their application and to use it to maximum advantage by following the straightforward instructions provided. This book contains chapters on colorimetric, bioluminescent, chemiluminescent, fluorescent, and time-resolved fluorescent detection methods. Each chapter has been written by the inventor or developer of a particular nonisotopic method and thus provides an expert account of the method. Each chapterpresents useful background information and detailed, step-by-step, easy-to-follow, experimental procedures for labeling and detection. Gives extensive practical information Covers major types of nonisotopic labels and procedures Presents background information for each method Provides strategies and detailed experimental procedures for labeling and detecting DNA sequences by Fluorescence Chemiluminescence Bioluminescence Colorimetry

Nucleic Acid Probes


Book Description

With each chapter written by a distinguished expert in the biochemistry field, this comprehensive volume describes the preparation and use of a variety of radioactive and non-radioactive probes in situations ranging from research laboratories to routine diagnosis laboratories. The enzymatic and chemical techniques for labeling nucleic acid probes with radioisotopes and with non-radioactive ligands and haptens are discussed. Additionally, the associated methods for their detection, the use of these probes in the diagnosis of human and microbial pathogens, of plant viruses and viroids, and of human genetic disorders, as well as in the detection of nucleic acids in tissues and cells by in situ hybridization are presented.




Protocols for Nucleic Acid Analysis by Nonradioactive Probes


Book Description

Protocols for Nucleic Acid Analysis by Non-radioactive Probes, Second Edition provides a firm background on the basic preparative protocols required for the analysis of nucleic acids by nonradioactive methods.

New fluorescent techniques such as Real Time PCR and microarrays are also included, allowing users to get a nonradioactive protocol implemented in the laboratory with minimum adaptation required and fastest time to results. The protocols follow the successful Methods in Molecular BiologyTM series format, each offering step-by-step laboratory instructions, an introduction outlining the principles behind the technique, lists of the necessary equipment and reagents, and tips on troubleshooting and avoiding known pitfalls.




Nonisotopic Probing, Blotting, and Sequencing


Book Description

Since the publication of Nonistopic DNA Probe Techniques in 1992, the move away from radioactive materials for research and diagnostics has continued. This is due in part to public awareness of the hazards of radioactive waste and laws making radioactive disposal more difficult and costly and to improvement in both the sensitivity and convenience of nonisotopic techniques. Several new nonisotopic techniques have been developed and substantial improvements made to existing nonisotopic methods since 1992, and these are now included in Nonisotopic Probing, Blotting, and Sequencing. Nonisotopic Probing, Blotting, and Sequencing is an updated, expanded edition of the bestseller, Nonisotopic DNA Probe Techniques. It has been thoroughly revised to include the latest improvements in nonisotopic tagging techniques for macromolecules. Like its predecessor, it enables researchers to select the best nonisotopic method for their needs and maximize success by following its straightforward protocols. Provides strategies and detailed procedures for labeling, blotting, and probing specific nucleic acid sequences and, with this edition, protein molecules Gives protocols for nonisotopic DNA sequencing - new in this edition Gives extensive, practical information Presents background information for each method Provides expert accounts from the inventor or developer of each method Contains seven entirely new chapters Covers all major types of nonisotopic procedures for labeling and detection




Hybridization with Nucleic Acid Probes, Part II


Book Description

Recent breakthroughs in recombinant DNA technology and the availability of sophisticated equipment accessible to almost any laboratory, have contributed to the development and perfection of powerful hybridization tools. Recently, nucleic acid hybridization has not only become a cornerstone in molecular biology research but also a powerful supplement to other diagnostic tools.These diagnostic methods are set out in a logical and clear two-part volume in this now famous Laboratory Techniques series. The volume is divided into theory and preparation (Part I), and probe labelling and hybridization techniques (Part II). Both parts are worthy additions to this series, designed for easy access of information on the laboratory bench.




Nonradioactive Analysis of Biomolecules


Book Description

Highly sensitive systems which are widely used in molecular biological & biomedical laboratories, such as colorimetric, luminescence, fluorescence measuring using antibody-antigen binding or hybridisation, as well as PCR amplification are described in detail.




In Situ Hybridization: Medical Applications


Book Description

In situ hybridization has developed as a means of localizing specific DNA and RNA sequences within tissues. The great strength of this approach is the ability to relate the distribution of specific nucleic acids with cell structures and the protein products of the target gene by means of immunohistochemistry. Complementary DNA, RNA or oligonucleotide probes, suitably labelled, are hybridized to specific DNA or RNA targets within tissues. The spatial information thus obtained has contributed greatly to our understanding of such diverse areas of research as gene mapping, viral infection, cytogenetics, protein synthesis, prenatal diagnosis and tissue grafting. This book is not intended as another recipe book, although it does describe theoretical and practical aspects of the technology. Rather, the authors critically describe the contribution made by in situ hybridization to specific areas of medical research.
