Biotin-11-dUTP (CAS 1221498-88-9) is a biotin-conjugated analogue of deoxythymidine triphosphate (dTTP) that can be incorporated enzymatically into DNA or cDNA sequences during polymerase reactions After integration labeled nucleic acid fragments can be detected using streptavidin coupled to horseradish peroxidase (HRP) alkaline phosphatase (AP) fluorescent molecules or bead-based capture systems This approach is frequently utilized in polymerase chain reaction (PCR) nick translation reverse transcription assays and apoptosis studies facilitating DNA probe labeling and molecular analysis workflows
