Embodiments herein report compositions, systems and methods for making and using plasmid vectors and nanotube complexes. In certain embodiments, compositions, systems and methods herein include making plasmid vectors having aptamer inserts. In some embodiments, methods disclosed herein may be used to rapidly generate large quantities of plasmid vectors having aptamer inserts directed to a particular target agent. Other aspects concern plasmid constructs associated with organic semiconductors. Yet other aspects concern complexes of nanotubes associated with dsDNA aptamers and tracking molecules.

A PCR-based method for the identification ofis described. The method utilizes novel primer sets; designated 2Xlg3F (SEQ ID NO 3), 2Xlg3R (SEQ ID NO 4), 2Xlg3F(SEQ ID NO 5), 2Xlg3R(SEQ ID NO 6), 4XH1aF (SEQ ID NO 7), and 4XH1aR (SEQ ID NO 8).

DNA probes for specific genes of anthrax

The cell line HeLa is transformed with the chromosomal insertion of the plasmid pSV,neoNR10,, ATCC No. 69617. The transformed cells, HeLaNR1, produce diazoluminomelanin (DALM) intra cellularly when provided with nitrate, luminol and 3-amino-L-tyrosine&bull;HC1 (3AT). The modified cells can be used to study mechanisms for radiofrequency and light radiation interactions with carcinoma of the cervix. The effects of drugs, hormones, and cytokines that affect the expression of nitric oxide synthase and its activity can also be studied to understand the effects of these materials on cervix cells.

Nitrate reductase-transfected HeLa cells for cancer and microwave bioeffects research

In a recognition complex system, nucleic acid ligands comprising random DNA sequences are operatively coupled to an organic semiconductor and distributed so as to form an array of recognition complexes. When an unknown chemical or biological analyte is applied to the array, the electrical and/or photochemical properties of one or more of the recognition complexes are altered upon binding of the nucleic acid ligand to the analyte. The degree to which the electrical and/or photochemical properties change is a function of the affinity of the nucleic acid ligand sequence for the analyte. The electrical and photochemical changes associated with the array, as a whole, can be used as a unique signature to identify the analyte. In certain embodiments, an iterative process of selection and amplification of nucleic acid ligands that bind to the analyte can be used to generate a new array with greater affinity and specificity for a target analyte, or to produce one or more nucleic acid ligands with high binding affinity for an analyte. The present invention also provides methods for preparing nucleic acid ligands that bind with high affinity to an analyte and using such nucleic acid ligands to neutralize the analyte.

Organic semiconductor recognition complex and system

The cell line EMT-6 are transformed with the chromosomal insertion of the plasmid pSV.sub.2 neoNR10.sub.1, ATCC No. 69617. The transformed cells, EMT-6/pSV.sub.2 neoNR10.sub.1, produce diazoluminomelanin (DALM) intracellularly when provided with nitrate, luminol and 3-amino-L-tyrosine.multidot.HCl (3AT). The modified cells can be used to study mechanisms for radiofrequency and light radiation interactions with breast tumor cells in vitro and in mice. The effects of drugs, hormones, and cytokines that affect the expression of nitric oxide synthase and its activity can also be studied to understand the effects of these materials on breast tumor cells.

E. coli strain JM109 transfected with nitrate reductase gene containing plasmid pIC20RNR1.1 produces diazoluminomelanin when cultured in a medium containing nitrate, 3-amino-L-tyrosine and luminol, under suitable metabolic conditions.

Diazodenitrification in manufacture of recombinant bacterial biosensors

There is provided a method for producing diazoluminomelanin (DALM) which comprises culturing in a medium containing nitrate, 3-amino-L-tyrosine (3-AT) and luminol under suitable metabolic conditions, a microorganism containing nitrate reductase. Also provided is a method for directly detecting microorganisms containing nitrate reductase or those into which nitrate reductase can be introduced by recombinant DNA technology, which comprises culturing the microorganism in a medium containing nitrate, 3-amino-L-tyrosine (3-AT) and luminol under suitable metabolic conditions, transferring the medium to a microtiter plate or tube coated with antibody or an antiligand to which the microorganism would specifically bind, washing the plate or tube and activating luminescence. Further, there is provided a method for producing diazomelanin (DM) which comprises culturing in a medium containing nitrate and 3-amino-L-tyrosine (3-AT) under suitable metabolic conditions, a microorganism containing nitrate reductase. Yet further, there is provided a method for directly detecting microorganisms containing nitrate reductase or those into which nitrate reductase can be introduced by recombinant DNA technology, which comprises culturing the microorganism in a medium containing nitrate and 3-amino-L-tyrosine (3-AT) under suitable metabolic conditions, transferring the medium to a microtiter plate or tube coated with antibody or an antiligand to which the microorganism would specifically bind, washing the plate or tube, adding luminol and activating luminescence.

Mamammalian cell lines capable of enhanced nitrite production are by transfecting a murine macrophage or murine thymoma with barley nitrate reductase gene (NR).

Enhanced nitrite production in transfected murine cells

A diagnostic test for environmental bacillus which comprises the steps of inoculating an agar growth medium comprising a nitrate source, luminol and 3-amino-L-tyrosine (3AT) with the sample, incubating the inoculated medium and determining the presence of the bacillus. The novel medium preferably comprises potassium nitrate, luminol, 3-amino-L-tyrosine and trypticase soy agar. Antibiotics and/or a specific bacteriophage may be added to the medium surface in localized areas to show specific bacterial lysis for identification. The novel medium and the methods of this invention are suitable for the identification of B. anthracis.
