Definitions

  • This invention relates to the detection of nucleic acid sequences and more specifically to a process of combining amplification of target nucleic acid sequences with detection of a reporter group specifically incorporated into the target sequence followed by affinity capture.
  • Patent 4,358,535, issued to Falko describes a method of culturing cells to increase their number and thus the amount of nucleic acid of the organism suspected to be present, depositing the sample onto fixed support, and then contacting the sample with a labeled probe, followed by washing the support and detecting the label.
  • One drawback to this method is that without culturing the organism first, the assay does not have adequate sensitivity. Adding a culture step, however, is time consuming and not always successful.
  • Maniatis et al., Molecular Cloning: A Laboratory Manual. Cold Spring Harbor Laboratory, pp.390-401 (1982) describe a method in which a nucleic acid of interest is amplified by cloning it into an appropriate host system. Then, when the host organism replicates in culture, the nucleic acid of interest is also replicated. This method also suffers from the requirement to perform a culture step and thus provides for a procedure that is time consuming and complicated.
  • An advantage of this method is that it can rapidly produce large quantities of a small portion of the sequence of the nucleic acid of an organism of interest.
  • a disadvantage of this method is that the detection of the nucleic acids produced, using a direct assay method, is complicated in that the amplification process can produce nucleic acid sequences which are not faithful copies of the original nucleic acid which was to be copied. These erroneous nucleic acid sequences can provide false positives in the assay which increase the background noise and thus decrease the sensitivity of the entire method.
  • any unhybridized reporter probe is washed away followed by the detection of the label incorporated into the complex bound to the solid support.
  • An advantage of this technique over that disclosed by Ranki et al. is that the hybridization, which takes place in solution, is favored kinetically.
  • Some disadvantages are that the length of the target nucleic acid affects the overall efficiency of the reaction which decreases with increasing target nucleic acid length.
  • sandwich nucleic acid probe assays whether heterogeneous two-step or one-step, or utilizing solution hybridization, are not as sensitive as the direct assay method.
  • the nucleic acid assay of this invention for the detection and/or measurement of a preselected nucleic acid sequence in a sample suspected of including a nucleic acid containing said preselected sequence comprises the steps of: (A) rendering the target nucleic acid single- stranded; (B) amplifying at least one specific nucleic acid sequence contained within the preselected nucleic acid sequence in the presence of at least one deoxyribonucleotide triphosphate containing a reporter moiety in an amount up to the total replacement of the corresponding dNTP, by (1) treating the strands with two oligonucleotide primers, for each different specific sequence being amplified, under conditions such that for each different sequence being amplified an extension product of each primer is synthesized which is complementary to each nucleic acid strand, wherein said primers are selected so as to be sufficiently complementary to the different strands of each specific sequence to hybridize therewith such that the extension product synthesized from one primer, when it
  • step (3) treating the single-stranded molecules generated from step (2) with the primers of step (1) under conditions that a primer extension product is synthesized using each of the single strands produced in step (2) as a template;
  • step (C) contacting the product of step (B) with a solid affinity support matrix
  • the nucleic acid assay of this invention comprises the following overall process for the detection of target nucleic acids of a preselected sequence : a) Using the polymerase chain reaction (PCR) nucleic acid amplification method described in U.S. 4,683,202, incorporated herein by reference, specific nucleic acid sequences are amplified by annealing the denatured target nucleic acid present in the sample with primers specific for the target and forming extension products.
  • a deoxyribonucleotide triphosphate containing a reporter group (moiety) dNTP-R, is used to replace some or all of at least one of the corresponding deoxyribonucleotide triphosphates employed.
  • Each extension product formed is complementary to a portion of the preselected nucleic acid sequence contained within the target nucleic acid and becomes " a template for further primer binding. This process is then repeated as necessary in order to produce the desired amount of primer extension product for detection and/or measurement.
  • the resulting nucleic acid is brought in contact with an affinity support and allowed to bind to the affinity support for a period of from 1 to 30 minutes .
  • the affinity support is then rinsed with an appropriate buffer in order to remove non-incorporated reporter group modified deoxyribonucleotide triphosphate.
  • PCR as used herein in referring to the process of amplifying target nucleic acid sequences employing primer oligonucleotides to produce by enzymatic means a greatly increased number of copies of a small portion of the target nucleic acid is described in U.S. patent 4,683,202.
  • the PCR target amplification reaction requires approximately 20 to 30 repeat cycles in order to produce a sufficient quantity of the amplified target nucleic acid for further hybridization.
  • Denaturation of the amplified nucleic acid can be accomplished by treatment with alkali, acid, chaotropic agents, or heat, although the preferred method is to place the amplified target nucleic acid in a boiling water bath for at least 10 minutes followed by a chilled water bath (4°C) for at least two minutes.
  • affinity supports can be utilized.
  • affinity membranes such as Gene Screen® hybridization transfer membrane (a registered trademark of E. I . du Pont de Nemours and Company; a nylon-based membrane) , nitrocellulose, and Gene Screen PlusTM, a positively charged and supported nylon 66 membrane.
  • Gene Screen® hybridization transfer membrane a registered trademark of E. I . du Pont de Nemours and Company; a nylon-based membrane
  • nitrocellulose nitrocellulose
  • Gene Screen PlusTM Gene Screen PlusTM
  • a variety of known detection methods can be utilized in the assay of this invention, depending upon the reporter group incorporated into the amplified product.
  • the reporter group is a chromophor or fluorophor
  • the incorporated reporter group can be detected by known spectroscopic techniques.
  • a labeled antibody to the reporter group incorporated during the amplification process is employed. It is brought into contact with the amplified product before or subsequent to capture of the amplified product . The label on the antibody can then be used to detect the presence of the amplified product.
  • Aliquots of serial dilutions (lxl0 +7 , lxl0 +6 , lxl0 +5 , lxl0 +4 f lxlO +3 , lxl0 +2 , lxl0 +1 , and zero copies) of plasmid pBH10-R3 can be amplified using PCR.
  • Each aliquot can be combined with a buffer 200 ⁇ M in each of dATP, dTTP, dCTP, and dGTP, and 10 ⁇ M in succinyl-fluorescein dTTP, 1.0 ⁇ M in each of Primer A and Primer B, and containing 1 ⁇ g of human placental DNA/reaction and 2.5 units of a DNA polymerase enzyme, in a total reaction volume of 100 ⁇ l .
  • Each reaction mixture can then be temperature cycled as described in the product bulletin thirty (30) times.
  • This process is expected to result in the estimated increase in the number of target molecules by lxl0 +5 to lxl0 +6 .
  • the product of Step A can be adsorbed onto a microtiter plate having a bottom composed of Gene Screen Plus for 30 minutes at 25°C.
  • the microtiter plate wells can then be washed three times for 5 minutes at 25°C by adding 200 ⁇ l of wash buffer containing IX SSC, pH 7.0, and 0.17% Triton X-100, and aspirating between washes.
  • Detention Detection can be accomplished by adding 200 ⁇ l of 10 mM Tris, pH 7.00 to each sample and detecting the amplified nucleic acid product detected by reflectance fluorescence visualization.
