Qualified reagents for the polyadenylation of microRNAs (miRNAs) from total RNA and synthesis of first-strand cDNA from the tailed miRNAs. Detects mature miRNA. Differentiate miRNA that differ by a single nucleotide. Sensitive detection down to 10 copies. Highly accurate results in 3 hours miRNA. Specific Forward Primers miRNA Primer Design Guidelines
The Prime It RmT random primer labeling kit uses random oligonucleotides as primers for labeling DNA to produce high-specific-activity probes.The procedure relies on the ability of random 9-mers to anneal to multiple sites along the length of a DNA template. The primer–template complexes formed represent a substrate for the magenta DNA polymerase, a thermostable polymerase that allows the Stratagene Prime-It RmT random primer labeling kit to be stored at room temperature. The enzyme synthesizes new DNA by incorporating nucleotide monophosphates at the free 3´-OH group provided by the primer. The newly synthesized DNA is made radioactive by substituting radiolabeled [α-32P]dCTP for unlabeled dCTP in the reaction mixture. The resulting labeled DNA serves as a sensitive hybridization probe for screening gene libraries,4 probing Southern and Northern blots,5,6 and in situ hybridization techniques.
Random oligonucleotides have been used as primers in a method for labeling DNA to produce high specific-activity probes.1,2 The procedure relies on the ability of random hexanucleotides to anneal to multiple sites along the length of a DNA template. The primer–template complexes formed represent a substrate for the Klenow fragment of DNA polymerase I. The enzyme synthesizes new DNA by incorporating nucleotide monophosphates at the free 3´–OH group provided by the primer. The newly synthesized DNA is made radioactive by substituting a radiolabeled nucleotide for a nonradioactive one in the reaction mixture. The resulting labeled DNA can serve as a sensitive hybridization probe for screening gene libraries,3 probing Southern and northern blots,4,5 and in situ hybridization techniques.
