DyNAzyme™ EXT DNA Polymerase is an optimized mixture of DyNAzyme™ II DNA Polymerase and a proofreading enzyme. It is a versatile and easy-to-use enzyme especially suited for handling demanding reaction conditions without time-consuming optimization. DyNAzyme EXT Polymerease offers exceptional performance that Taq based mixtures cannot match.
Thermo Scientific Klenow Fragment is the large fragment of DNA polymerase I. It exhibits 5'→3' polymerase activity and 3'→5' exonuclease (proofreading) activity, but lacks 5'→3' exonuclease activity of DNA polymerase I. Highlights • Incorporates modified nucleotides (e.g., Cy3-, Cy5-, aminoallyl-, biotin-, digoxigenin- and fluorescently-labeled nucleotides) • Active in restriction enzyme, PCR, RT, and T4 DNA Ligase buffers A…
Thermo ScientificT4 DNA Polymerase, a template-dependent DNA polymerase, catalyzes 5'-3' synthesis from primed single-stranded DNA. The enzyme has a 3'-5' exonuclease activity, but lacks 5'-3' exonuclease activity. Highlights • Stronger 3'-5' exonuclease activity on single-stranded than on double-stranded DNA and greater (more than 200 times) than DNA polymerase I, E. coli,and Klenow fragment (see Reference1) • Active in Therm…
Thermo Scientific T4 Polynucleotide Kinase (PNK) is a tetrameric protein composed of four identical subunits. It is widely used in molecular biology to radiolabel nucleic acids and to add a phosphate to the 5'-end of dephosphorylated nucleic acids to facilitate ligations. Features • Phosphorylates 5’ ends • Transfers 32P to DNA and RNA
Thermo Scientific Exonuclease I digests single-stranded DNA 3' to 5' (requires Mg2+ and a free 3'-OH). The nuclease is inactivated by heating at 80°C for 15 minutes.
Thermo Scientific Shrimp Nuclease is an endonuclease that cleaves phosphodiester linkages in DNA to yield di- and oligonucleotides with 5’-phosphate and 3’-hydroxyl termini. The enzyme has a high preference for double-stranded DNA, and can be used to selectively degrade dsDNA, leaving ssDNA and RNA intact. The enzyme is inactivated after 15 minutes at 65 °C.
Thermo Scientific RNase A (ribonuclease A) is supplied as a chromatographically pure freeze-dried powder, salt-free for easy reconstitution in most buffers.
Thermo Scientific Ribonuclease H (RNase H) is an endonuclease that degrades the RNA portion of DNA-RNA hybrids. It hydrolyses phosphodiester bonds of RNA in RNA:DNA heteroduplexes. It produces products with 3’-OH and 5’-phosphate. RNase H will not degrade single or double-stranded DNA or RNA.
Thermo Scientific Shrimp Alkaline Phosphatase (SAP) catalyzes the dephosphorylation of 5´ phosphates from DNA and RNA and is completely and irreversibly inactivated by heating at 65°C for 15 minutes. SAP is active on 5´ overhangs, 5´ recessed and blunt ends.
A cell-permeable (thienothienyl)amino-acetamide compound that displays anti-inflammatory properties. Acts as a potent, reversible, ATP-competitive, and highly selective inhibitor of IKK-2 (IC50 ~3-12 µM for IKK-2 homodimer, IKK-1/IKK-2 heterodimer, and IKK-2). Its specificity has been confirmed using a panel of 31 other kinases, including IKK isoforms IKK-1, IKK-i, and TBK-1 (IC50 > 200 µM). Shown to specifically block NF-kB-d…
