Avidin-biotin Complexes for Gene Probes

Gene probes can be produced in a variety of ways and fall into three types: gene-specific probes, oligonucleotide probes, and polymorphism probes. Gene-specific probes are produced from specific mRNA by reverse transcriptase, which synthesizes a complementary DNA copy (cDNA) from the mRNA. Traditional gene probes are synthesized from radioactive phosphate bases. Gene probes can be used in dot blot hybridization, where serially diluted DNA samples are preserved on DNA-binding membranes and complementary radiolabeled probes are in vitro, so that the amount of radioactive signal is directly proportional to the amount of target DNA present. The development of gene probes that recognize various DNA polymorphisms in non-coding sequences can realize the identification of abnormal genes and gene products at the molecular level. In recent years, biotin has been introduced into DNA probes, which are analyzed using appropriate conjugates containing avidin or streptavidin.
