FAM-11-dUTP, 6-isomer

Product Introduction

6-FAM-11-2’-deoxyuridine-5’-triphosphate, trilithium salt, is a common agent for non-radioactive DNA labeling.,FAM (fluorescein) is a popular green-fluorescent dye with an emission maximum at 513 nm. This derivative is a pure FAM 6-isomer.,6-FAM-11-dUTP is a modified triphosphate that can be incorporated into DNA instead of dTTP by various enzymes, including Klenow fragment, Taq-Polymerase, DNA-Polymerase I, Phi 29 Polymerase, reverse transcriptase or terminal transferase.,In contrast to triphosphates with a dye directly linked to aminoallyl-dUTP, this triphosphate contains a linker of 11 atoms between the fluorophore and the nitrogenous base. This linker length prevents FAM-label from potential static quenching and increases the efficiency of nucleotide incorporation during DNA synthesis.,6-FAM-11-dUTP can be used to produce a labeled product during PCR and cDNA synthesis and for labeled DNA-probes synthesis by random primed labeling and Nick-translation. Synthesized fluorescence-labeled DNA probes can be used to detect specific sequences by Southern blot, Northern blot, in situ hybridization, or by microarray analysis.
