Definitions
- DNA or DNA prepared by PCR Polymerase Chain Reaction
- PCR amplified products are covalently or non-covalently bound to the substrate, for example, written in Science, Vol. 270, 467-470 (1995) and Nucleic Acid Research, Vol. 22, 5456-5465 (1994).
- the DNA (or RNA) is dissolved in a salt solution such as SSC (sodium chloride/sodium citrate) with or without a denaturing process.
- SSC sodium chloride/sodium citrate
- oligonucleotides and short length DNAs are difficult to immobilize using this method. Even when long length DNA (greater than 0.3 Kb) are attached non-covalently, the processes of washing and hybridization can remove DNA from the substrate, which may cause a reduction in detectability of the target nucleic acid.
- a substrate which is applicable for the supersensitive detection of the target nucleic acid, and suitable for the immobilization of many types of nucleic acid, including both short and long length nucleic acids, single stranded nucleic acids, double stranded nucleic acids, DNA, and RNA is desirable.
- the invention is primarily concerned with the substrate for nucleic acid immobilization; specifically a polyanion based surface for attachment of nucleic acids.
- the polyanion is polyacrylic acid, however any polyanion may be used.
- Another aspect of the invention involves the immobilization of the nucleic acid to the substrate via a covalent bond.
- the preferred method involves transforming the carboxylic acid functionalities into activated esters.
- the activated esters are then reacted with amine modified nucleic acids.
- the substrate is a non-porous surface.
- a preferred form being glass.
- the fourth embodiment is concerned with the method(s) for nucleic acid immobilization to the substrate; i.e. the method for nucleic acid immobilization to the substrate where the substrate coated with an activated ester derivative of polyanion is contacted with amine-modified nucleic acid.
- the polyanion is polyacrylic acid and the substrate is non-porous as the preferable form; glass is the best non-porous substrate.
- the nucleic acid(s) is modified with functional group(s) that has reactivity to the activated ester derivative, in the preferable form the nucleic acid is modified with amino groups.
- the fifth embodiment is concerned with the detection method(s) for target nucleic acids in the specimen(s) (or sample(s)) including but not limited to a: a) Process, in which the substrate for nucleic acid immobilization is the activated ester derivative of the polyanion. The polyanion has been previously covalently attached to the surface of the glass slide. b) Reaction process between the activated ester derivative mentioned above and the nucleic acid modified with a functional group that has reactivity to the ester derivative. c) Hybridization process between nucleic acid immobilized on the substrate (target nucleic acid) and complementary nucleic acid (probe nucleic acid). d) Detection process for hybridized nucleic acids.
- the sixth embodiment is concerned with the detection method(s) for nucleic acid in the specimen including but not limited to a: a) Reaction between the activated ester derivative of the substrate and nucleic acid modified with a functional group that has reactivity to the activated ester derivative. b) Hybridization process between nucleic acid immobilized on the substrate and complementary nucleic. c) Detection process for hybridized nucleic acid.
- a polyanion is a polymer that contains two or more negative charges.
- nucleic acid includes deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) in the form of an oligonucleotide messenger RNA, anti-sense, plasmid DNA, parts of a plasmid DNA or genetic material derived from a virus (viral DNA) linear DNA, or chromosomal DNA.
- DNA deoxyribonucleic acid
- RNA ribonucleic acid
- the substrate(s) for nucleic acid immobilization is not restricted if it is applicable for DNA chips or biosensors.
- the substrate consists of a solid support having a non-porous and smooth surface, materials such as glass slides or silica beads are good to use, in the preferable form.
- the substrate is treated with 3 -aminopropyltriethoxy silane to provide the surface of the substrate with functional groups capable of reacting with the polyanion (amino groups in this case).
- Any silane capable of introducing functionality onto the surface of a glass substrate can be used in this innovation.
- the polyanion can then be covalently attached to the silanated surface of the substrate via a carbodiimide coupling reaction.
- Polyanions contain acidic functional groups such as carboxyl groups, phosphate groups, sulfate groups, and so on which have the effect of preventing non-specific binding (electrostatic) with probe nucleic acids.
- the polyanion is covalently attached to the surface of the substrate; polyacrylic acid, polyglutamic acid, polyaspartic acid, and polyphosphate, are the preferable forms.
- These polyanions are attached to the silanated surface of the substrate through carbodiimide (or other activated ester chemistry) chemistry.
- an activated ester For example pentafluorophenol and imidazole esters are activated ester derivatives available for the carboxyl group and phosphate group, respectively.
- an activated ester There are no special restrictions placed on the nucleic acid to be immobilized on the substrate. All of the synthesized oligonucleotides, polynucleotides, and their derivatives can be useful. Both single and double stranded forms of nucleic acids (DNA or RNA) are available. The derivatives are not restricted if they have modifications enabling immobilization onto the substrate surface.
- the derivative(s) modified with amino group, thiol group, phosphate group, and aldehyde group at DNA 5' terminus are examples.
- the derivatives modified at 5' terminus with a cross linker or linker as the spacer such as alkylamine are also available.
- the modification at the 5' terminus is especially effective for the immobilization of short nucleic acids such as oligonucleotide. Any nucleic acid covalently modified to introduce various functional or signaling groups may also be used, Minis' LabellT reagents may be used to modify nucleic acids.
- the substrate immobilized with nucleic acid is soaked into 0.3 M NaOH at room temperature for 5 min or boiling water for 2 min to denature the nucleic acid, washed with distilled water and absolute ethanol, and dried.
- the activated ester groups not reacted with nucleic acid in the are hydrolyzed back to carboxylic acid moieties (i.e. negatively charged).
- the acid groups prevent nonspecific electrostatic binding between probe nucleic acid and the substrate.
- the succinic anhydride blocking process necessary for polylysine slides can be omitted. These acid groups also lower the background signal.
- target nucleic acids including oligonucleotides
- the blocking process can be omitted after immobilization
- the nonspecific binding between the target nucleic acid and the substrate is kept to a minimum
- PCR was performed by using phage DNA as a template and with following two combinations of primers; that of Primer S and Primer A 1000 shown as Sequence #3 and #4, respectively, and that of Primer S and Primer A300 as Sequence #5, in Sequence
- Each DNA fragment was dissolved in 20 mM MOPS buffer (pH 7.5), the array was made by GMS 417 arrayer (Genetic MicroSystems) on the glass slide with amino groups on its surface, which is commercially available.
- the glass slide used was poly-L- lysine coated POLY-PREP-SLIDES (Sigma: abbreviated as PLL coated slide glass) and MAS, amino alkyl silane family, coated slide (Matsunami Glass Ind.: abbreviated as MAS coated slide glass), these slides are widely used for the preparation of DNA chips.
- the spots were established with the size and intervals of 150 Hi and 375 Hi, respectively. Five spots of same DNA were arrayed.
- a portion of slide(s) was treated with absolute succinic anhydride to block the free amino group(s) on the substrate surface by succinylation.
- the blocking solution was prepared by the mixing of 1.5 g succinic anhydride resolved in 89.5 ml of N-methyl-2- pyrrolidone with 9 ml of 1 M borate buffer (pH 8.0), the slide was soaked in the blocking solution for 20 min at the room temperature. The treated slide was washed with distilled water thoroughly, boiled in water bath for 3 min, and exposed to ice cold ethanol to denature DNA. Ethanol was removed by low speed centrifugation. After that, slide was air dried and stored in a desiccator.
- Fluorescently labeled PCR fragments of different lengths were prepared by the PCR using one primer of the pairs labeled with Rhodamine X (PE Biosystems: abbreviated as ROX) at 5' terminus and pT7TFR as primer and template, respectively; i.e., the PCR was performed using the primer pairs of S7 (Sequence #8) labeled with ROX and AS4 (Sequence #10), AS3 (Sequence #11), AS2 (Sequence #12), or AS1 (Sequence #13). Resulting in 1.0, 0.5, 0.2, and 0.1 kb fragments, respectively, being prepared.
- ROX Rhodamine X
- each DNA fragment was dissolved in 20 mM MOPS buffer (pH 7.5) and aminated using the Amino Label IT ® reagent; i.e., the Amino Label IT ® reagent was dissolved in dimethyl sulfoxide and added into the purified DNA solution as 1/5 ratio (W/W) and incubated at 37 BE for 1 h.
- Each aminated DNA was purified by ethanol precipitation method.
- Example #2-(l) Two types of 1.0 Kb and 0.3 Kb lambda phage DNA fragments with amino group at their ends were prepared by the same method in Example #2-(l). A portion of the DNA was aminated using the Amino Label IT ® reagent as described Example #4. Each DNA fragment was dissolved in 20 mM MOPS buffer (pH 7.5) at a final concentration of 0.5 mg/ml, and spotted in seven different places onto activated ester coated slide glass and MAS coated slides.
- Nucleic acid arrays made on each slide glass were hybridized with fluorescent Cy3-labeled DNA probes, and the resulting signals were analyzed. That is, a 1.0 Kb lambda phage fragment prepared above was labeled with Cy3 using Label IT ® Cy3 Labeling Kit (Minis) according to the manufacturers recommendations. Using this Cy3 labeled DNA probe, hybridization and washing were performed as the described in Example #4.
- DNA chip fluorescence i.e. signal intensity
- GMS 418 array scanner with emission wavelength as 532 nm and excitation wavelength as 570 nm.
- the obtained images were analyzed and the values of the signal strength were converted to numerical data using the image analyzing software ImaGene.
- the relative fluorescent strength was calculated by that of spot on MAS coated slide glass as 100. The result obtained was summarized in Table 4. Table 4
