  • Patent number: 8465921
    Abstract: Conjugates between a minor groove binding molecule, such as the trimer of 1,2-dihydro-(3H)-pyrrolo[3,2-e]indole-7-carboxylate (CDPI3), and an oligonucleotide form unusually stable hybrids with complementary target sequences, in which the tethered CDPI3 group resides in the minor groove of the duplex. These conjugates can be used as probes and primers. Due to their unusually high binding affinity, conjugates as short as 8-mers can be used as amplification primers with high specificity and efficiency. MGB conjugation also increases the discriminatory power of short oligonucleotides, providing enhanced detection of nucleotide sequence mismatches by short oligonucleotides.

  • Patent number: 6548652
    Abstract: Derivatized oligonucleotides (ODNs) are coupled to a solid support in improved yield resulting in a high density of coupled oligonucleotide per surface unit of the support, through a Schiff base type bond formed between an NH2 group attached either to the solid support or to the ODN and an aromatic aldehyde attached to the other of the solid support and the ODN. The preferred solid support-ODN conjugate is formed between semicarbazide groups attached to a glass surface and an aromatic aldehyde attached at either 3′, or 5′ end of an ODN or to an intermediate nucleotide of the ODN.

  • Patent number: 5876479
    Abstract: Manufacturing procedures and compositions for soil enhancers and the like are disclosed. A solution is formed from adding humate to water under constant agitation. Sodium Bicarbonate is added to the solution, resulting in a reaction allowing silica to precipitate out of the solution. The resulting solution is about 12% humic acid. Additional water is added to the solution along with a series of crude protein sources, including fish protein, blood extract, and feather meal. Following the addition of each protein source to the humic acid solution, citric acid is added to increase the protein solubility. Sarsaponins (Yucca extract) is then added to stabilize microbial activity. Additional water is added to the resulting mix, followed by the addition of sugar beet waste lime (calcium carbonate). The calcium carbonate brings the mixture to a pH of about the range of 6.8 to 7.2, which has been found to be encouraging for microbial activity. Seaweed is then added to the mix.
