Hapten-labeled nucleotide analogs for enzymatic incorporation, for indirect detection.
Biotin labeled dideoxyadenosine triphosphate (ddATP) is biologically active and can be incorporated with a variety of DNA polymerases including Taq, Klenow fragment, and Sequenase™. It terminates further incorporation and enables identification of the complementary base for applications like DNA sequencing and detection of point mutations. Biotin-labeled products may be detected with streptavidin conjugates. For the highest sensitivity in detection, we recommend using a streptavidin-HRP conjugate with tyramide signal amplification (TSA).
The number “11” in the compound name refers to the length of the linker arm between ddATP and the label.
TSA reduces exposure timein an imaging assay for PKCa. Protein kinase C alpha (PKCa) is associated with a wide variety of cellular processes including proliferation, adhesion and motility.
2’,3’-dideoxynucleotide analogs are biologically active with a variety of DNA polymerases, and are chain terminators. Some analogs demonstrate variations in relative performance depending upon nucleotide and label (fluorophore or hapten) selected due to enzyme preferences.
