Thermo Scientific Random Hexamer Primer is a mixture of single-stranded random hexanucleotides with 5'- and 3'-hydroxyl ends. The primer is supplied as a ready-to-use, 20X concentrated aqueous solution (24 μg at 100 μM).

Invitrogen Oligo(dT)16 Primer is a homo-oligomeric deoxyribonucleotide poly(dT) that is non-phosphorylated and chemically synthesized. It is used for priming and reverse transcription of polyadenylated poly(A)+ mRNA. Five nmoles of Oligo (dT)16 Primer is supplied in 100 μL of 10 mM TE, pH 7.

Random Hexamers are short oligodeoxyribonucleotides of random sequence [d(N)6] that anneal to random complementary sites on a target DNA or RNA to serve as primers for DNA synthesis by a DNA polymerase or reverse transcriptase.

Random Primers are oligodeoxyribonucleotides (mostly hexamers) used to prepare labeled DNA probes from templates for filter hybridization or in situ hybridization and to prime mRNAs with or without poly(A) for cDNA synthesis.

Ambion Bio-16-UTP 10 mM (Biotinylated UTP) is intended for use as substrate in in vitro transcription reactions. These modified nucleotides can be utilized by a variety of RNA polymerases, including T7, T3, and SP6 RNA polymerases, as well as other RNA modifying enzymes.

Oligo(dT)12-18 Primer is suitable for use in first-strand cDNA synthesis with reverse transcriptase. The primer hybridizes to the poly(A) tail of mRNA. It is phosphorylated on the 5´ end to facilitate cloning of cDNA.

This set of oligonucleotides is designed for template switching reverse transcription reaction and following preamplification of obtained cDNA. Template Switching Oligonucleotide (TSO) and Capturing Oligo (dT) are used during cDNA synthesis reaction to incorporate adaptor sequences in both ends of...

Thermo Scientific Exonuclease-Resistant Random Primer is a mixture of single-stranded random oligonucleotides used for highly efficient random priming of various DNA synthesis reactions.
