Why is "Aminoallyl" trending?

Wikipedia Overview

Aminoallyl nucleotide is a nucleotide with a modified base containing an allylamine. They are used in post-labeling of nucleic acids by fluorescence detection in microarray. They are reactive with N-Hydroxysuccinimide ester group which helps attach a fluorescent dye to the primary amino group on the nucleotide. These nucleotides are known as 5-(3-aminoallyl)-nucleotides since the aminoallyl group is usually attached to carbon 5 of the pyrimidine ring of uracil or cytosine. The primary amine group in the aminoallyl moiety is aliphatic and thus more reactive compared to the amine groups that are directly attached to the rings (aromatic) of the bases. Common names of aminoallyl nucleosides are initially abbreviated with aa- or AA- to indicate aminoallyl. The 5-carbon sugar is indicated with or without the lowercase "d" indicating deoxyribose if included or ribose if not. Finally the nitrogenous base and number of phosphates are indicated.
