Biotin-16-dCTP
Based on 1 Customer Validation
Biotin-16-dCTP is a biotinylated deoxycytidine triphosphate that serves as an important DNA labeling substrate. Biotin-16-dCTP can be enzymatically incorporated into the 3' end of DNA probes via terminal deoxynucleotidyl transferase, forming a 1-3 nucleotide-long tail to achieve biotinylation of the probes. Biotin-16-dCTP enhances chemiluminescent detection of low-abundance targets such as specific tRNA isoacceptors through Northern blotting. Biotin-16-dCTP can also replace conventional dCTP to be integrated into single-stranded DNA generated by asymmetric polymerase chain reaction, which is applicable for bioconjugation or pull-down assays. Repeated freeze-thaw cycles of Biotin-16-dCTP should be avoided to prevent degradation of its function for probe biotinylation.

Biological Activity
Biotin-16-dCTP (0.1 mM; 60 min at 37 °C) enables enzymatic biotinylation of DNA probes to produce 1-3 nt biotin tails, which enhance the sensitivity of chemiluminescent Northern blotting for detecting specific tRNAs and tRNA-derived fragments from Shewanella glacialimarina and Saccharomyces cerevisiae[1].
Biotin-16-dCTP (0.01 mM; 60 min) successfully adds 1-3 biotin moieties to DNA oligonucleotide probes, generating high-signal probes suitable for chemiluminescent northern blot detection of specific tRNAs and tRNA-derived fragments from Shewanella glacialimarina TZS-4T and Saccharomyces cerevisiae BY4741[2].
Biotin-16-dCTP (up to 100% replacement of canonical dCTP) is incorporated into ssDNA synthesized via aPCR[3].
