Amino-11-CTP

Amino-11-CTP is a click-chemistry compatible nucleotide analog built on a CTP-derived scaffold, designed for bioorthogonal labeling workflows that rely on strain-promoted or catalyst-free coupling strategies. The reagent’s anionic, phosphate-rich character and nucleoside compatibility make it well suited for incorporation into nucleic-acid related assays and for building defined chemical handles on RNA or related biomolecular constructs. In research settings, Amino-11-CTP is commonly selected to generate functional, probe-bearing nucleic acid materials for downstream imaging, binding studies, and diagnostic-reagent development.

1. RNA Labeling Workflows

Amino-11-CTP is used as a chemically addressable nucleotide building block in RNA labeling and transcript modification workflows, enabling installation of a reactive functional group at defined positions during enzymatic nucleic-acid synthesis or extension. Researchers use it to create RNA probes with controlled chemical functionality for subsequent coupling to fluorophores, affinity tags, or other reporter moieties. The “11” spacer length supports practical conjugation spacing, which can improve accessibility of the appended label in complex hybridization or assay formats. This makes Amino-11-CTP a frequent choice for generating chemically defined RNA reagents used in molecular biology toolkits, binding assays, and platform development for nucleic-acid detection chemistry.

2. Molecular Imaging Probes

Amino-11-CTP supports the preparation of imaging-ready nucleic-acid probes by providing a built-in chemical handle that can be coupled to imaging dyes or reporter constructs. Molecular imaging and chemical biology groups use these labeled RNA reagents to visualize localization, track hybridization events, and map interactions in microscopy-based and fluorescence-based readouts. The nucleotide backbone helps maintain probe-like behavior compared with purely synthetic labeling strategies, while the click-compatible functionality enables modular exchange of reporters to match instrument requirements and experimental constraints. As a result, Amino-11-CTP is often integrated into probe pipelines where rapid, standardized labeling of RNA constructs is needed for high-throughput imaging reagent generation.

3. Diagnostic Reagent Development

Amino-11-CTP is applied in the development of diagnostic and analytical reagent components that rely on nucleic-acid recognition coupled to a chemically tunable signal output. In assay development labs, it is used to generate labeled RNA or RNA-derived reagents that can be further conjugated to detection chemistries such as fluorescent reporters, chemiluminescent tags, or affinity capture moieties. The ability to introduce a reactive handle during nucleic-acid synthesis helps streamline reagent manufacturing by reducing post-synthetic modification steps and improving batch-to-batch consistency of labeling patterns. This positions Amino-11-CTP as a practical building block for constructing robust assay reagents used in research diagnostics, analytical chemistry workflows, and platform prototyping.

4. Biomaterial and Surface Conjugates

Amino-11-CTP is also used to create nucleic-acid functional materials where chemical coupling enables immobilization onto surfaces or incorporation into biomaterial assemblies. Materials scientists and chemical engineers leverage click-compatible nucleic-acid constructs derived from Amino-11-CTP to produce surface-tethered probes for biosensing, microarray-style platforms, and engineered hybrid materials. The nucleotide-derived architecture supports predictable probe presentation, while the spacer and reactive functionality facilitate efficient coupling to surface chemistries or to polymer/particle conjugation strategies. This application is particularly relevant when stable, spatially organized nucleic-acid interfaces are required for controlled binding studies and for building modular materials libraries.
