ENHANCED DEPOSITION OF CHROMOGENS UTILIZING PYRIMIDINE ANALOGS |
摘要 |
This disclosure relates to compositions that enhance the deposition of detectable moieties on tissue samples, methods utilizing these compositions and kits including these compositions. The compositions include a deposition enhancer having a formula;;where R1, R2, R3, and R4 are independently selected from aliphatic, aryl, halogen, a heteroatom-containing moiety, and hydrogen; R1 and/or R3 can be bound to R2 to form a fused, aromatic ring system; R5 is selected from a heteroatom-containing moiety; A is selected from, a carbon atom, a heteroatom, other than sulfur, and any combination thereof; n is 1-5, an enzyme, a specific binding moiety and a detectable moiety. |

1. A composition for detecting a target in a sample by proximally depositing a marker, comprising:
a pyrimidine and/or pyridine deposition enhancer having a formulawherein R1, R2, R3, and R4 are independently selected from aliphatic, aryl, halogen, a heteroatom-containing moiety, and hydrogen; R1 and/or R3 can be bound to R2 to form a fused, aromatic ring system; R5 is a heteroatom-containing moiety; A is carbon, a heteroatom other than sulfur, and any combination thereof; and n is 1-5;
a second deposition enhancer; and an enzyme substrate. |
