What is the temperature limitation of RNaseOUT Recombinant Ribonuclease Inhibitor (Cat. No. 10777019)?
RNaseOUT Recombinant Ribonuclease Inhibitor (Cat. No. 10777019) unit reaction conditions are defined at 25 degrees C. The upper temperature limit for full functionality is 40 degrees C. The enzyme half-life is decreased as temperatures increase above 40 degrees C. There is some residual activity up to 50-55 degrees C but heating at 65 degrees C will inactivate the enzyme. As RNaseOUT can be used in various applications like cDNA synthesis, RT-PCR, and in vitro transcription, the recommendation is to follow the temperature settings required for the respective method.
The catalytic domain of RNase E shows inherent 3' to 5' directionality in cleavage site selection.

'RNase E, a multifunctional endoribonuclease of Escherichia coli, attacks substrates at highly specific sites. By using synthetic oligoribonucleotides containing repeats of identical target sequences protected from cleavage by 2''-O-methylated nucleotide substitutions at specific positions, we investigated how RNase E identifies its cleavage sites. We found that the RNase E catalytic ... More

'We have cloned and characterized a human cDNA that belongs to the histone deacetylase family, which we designate as HDAC11. The predicted HDAC11 amino acid sequence reveals an open reading frame of 347 residues with a corresponding molecular mass of 39 kDa. Sequence analyses of the putative HDAC11 protein indicate ...

Development of reverse transcription (RT)-PCR and real-time RT-PCR assays for rapid detection and quantification of viable yeasts and molds contaminating yogurts and pasteurized food products.
Reverse transcriptase PCR (RT-PCR) and real-time RT-PCR assays have been used to detect and quantify actin mRNA from yeasts and molds. Universal primers were designed based on the available fungal actin sequences, and by RT-PCR they amplified a specific 353-bp fragment from fungal species involved in food spoilage. From experiments ... More
Regulation of H-ras splice variant expression by cross talk between the p53 and nonsense-mediated mRNA decay pathways.

When cells are exposed to a genotoxic stress, a DNA surveillance pathway that involves p53 is activated, allowing DNA repair. Eukaryotic cells have also evolved a mechanism called mRNA surveillance that controls the quality of mRNAs. Indeed, mutant mRNAs carrying premature translation termination codons (PTCs) are selectively degraded by the ... More
Biochemistry of mitochondrial nitric-oxide synthase.
Authors:Elfering SL, Sarkela TM, Giulivi C
Journal:J Biol Chem
PubMed ID:12154090
We reported that the generation of nitric oxide by mitochondria is catalyzed by a constitutive, mitochondrial nitric-oxide synthase (mtNOS). Given that this production may establish the basis for a novel regulatory pathway of energy metabolism, oxygen consumption, and oxygen free radical production, it becomes imperative to identify unequivocally and characterize ...
