    RIBOPROTECT RNase Inhibitor RT35. Inhibit ribonuclease activity

    RIBOPROTECT Hu RNase Inhibitor (RT35)

    The RIBOPROTECT Hu RNase Inhibitor is a 50 kDa recombinant human placental protein expressed in Escherichia coli. It inhibits ribonuclease (RNase) activity of common eukaryotic enzymes such as RNase A, RNase B, RNase C, and protects RNA integrity from degradation. RIBOPROTECT Hu is intended for use in applications where the presence of RNases may cause a hazard to RNA quality and experiment results, e.g. in RNA isolation, cDNA synthesis, RT-PCR, in vitro transcription and translation, or RNase-free monoclonal antibody preparation. It is compatible with DNA Polymerases and AMV or M-MuLV Reverse Transcriptases.

    RT32L-Reverse-Transcriptase-LYO- TRANSCRIPTME

    TRANSCRIPTME LYO Reverse Transcriptase (RT32L)

    TRANSCRIPTME LYO Reverse Transcriptase synthesizes a complementary DNA strand in the presence of a primer using either RNA (cDNA synthesis) or single-stranded DNA (ssDNA) as a template. TRANSCRIPTME LYO Reverse Transcriptase has increased thermal stability, which allows the reaction to be carried out at a higher temperature (optimum activity at 50°C). It increases the efficiency and specificity of those transcribed RNA regions which are rich in GC pairs and/or contain secondary structures. The enzyme has no 3’ –› 5’ exonuclease and reduced RNase H activity, which improves the synthesis of a full-length cDNA, even from long mRNA templates, using random priming. The enzyme gives high yields of first strand cDNA synthesis up to 7 kb long.

    RNase H

    RNase H (RT34)

    RNase H is a 18.9 kDa recombinant endoribonuclease purified from an Escherichia coli strain. The enzyme hydrolyses specifically the phosphodiester bonds of RNA hybridized to DNA and produces 5´ phosphate-terminated oligoribonucleotides and single-stranded DNA. The enzymes does not degrade single and double-stranded DNA or unhybridized RNA. It is a key enzyme in the removal of mRNA after first-strand cDNA synthesis. Treating cDNA with RNase H prior to PCR can improve sensitivity as RNA bonded to the cDNA template may prevent binding of the amplification primers in a PCR reaction. RNase treatment is often necessary when amplifying longer, full-length cDNA targets. In addition, this enzymes is useful for the removal of poly(A) tails on mRNAs after hybridization with oligo(dT) and also for the site-specific enzymatic cleavage of RNA.
