Digoxigenin (DIG)-labeled DNA probes produced from the PCR DIG Probe Synthesis Kit is suitable for low-(single)-copy gene detection of rare mRNA in Southern and northern blots. DIG-labeled DNA probes have also been used for labeling of DNA during in situ hybridization. The concentration of the supplied dUTP-nucleotide mix can be adjusted according to probe length. Labeling effectiveness can quickly be determined on an agarose gel. Stripping and reprobing of membranes is possible multiple times following the protocol in the package insert. One PCR labeling reaction (50 μl) will typically yield enough probe for 20 ml hybridization solution. The kit can be used for approximately 25 reactions (50 μl).
일반 설명
The PCR DIG Probe Synthesis Kit contains an alkali-labile digoxigenin (DIG)-11deoxyuridinetriphosphate (dUTP) formulation. This kit is for convenient and efficient generation of DIG-labeled DNA probes that are highly sensitive in polymerase chain reaction (PCR). The probes are labeled with DIG-11dUTP (alkali-labile), by the method of PCR. The ratio of DIG-dUTP:dTTP is 1:2. The PCR DIG Probe Synthesis Kit contains the Expand High Fidelity DNA polymerase mix. This robust enzyme mix with proofreading activity will polymerize probes 40 bp to 5 kb long using 10 pg plasmid DNA and 10 ng genomic DNA as template. The DIG-labeled probes are stable for over one year.
