Apexbio Technology LLC Biotin-16-dCTP 200ul (5 mM)
Biotin-16-dCTP is a biotinylated derivative of deoxycytidine triphosphate (dCTP) designed for enzymatic incorporation into nucleic acids during polymerase-mediated processes Structurally it consists of a dCTP core conjugated via a 16-atom spacer arm to a biotin moiety facilitating effective interaction with streptavidin This specific biotin-streptavidin binding affinity enables applications in nucleic acid labeling detection and affinity purification protocols PCR experiments indicate that biotin-16-dCTP incorporation by Taq polymerase can reach approximately 90% substitution without considerable reduction in amplification yield demonstrating greater polymerase compatibility compared to biotin-16-dUTP analogues
Apexbio Technology LLC Biotin-16-dUTP(Synonyms: Biotin-16-2'-deoxyuridine-5'-triphosphate, Biotin-16-dUTP nucleotide), 200ul (5 mM).
Biotin-16-dUTP is a biotin-labeled nucleotide analog utilized extensively in biomedical research for nucleic acid modification and detection Structurally modified to contain a biotin moiety linked via a 16-carbon spacer this compound functions by enzymatic incorporation into DNA strands mediated by DNA polymerases Following integration the biotin group serves as an affinity tag enabling subsequent detection through biotin-binding proteins such as streptavidin Applications include DNA labeling techniques in fluorescence microscopy and flow cytometry facilitating the visualization and analysis of nucleic acids in vitro
