General description

Recombinant, human ribonuclease inhibitor expressed in E. coli. Non-competitive inhibitor that inactivates RNase by non-covalent binding. Has been used to improve cDNA synthesis and in vitro RNA synthesis, increase yields of polysomes, and aid in the preparation of RNase-free antibodies. Inhibits RNases A, B, and C. Does not inhibit RNase T1 and S1 nuclease from Aspergillus.

Biochem/physiol Actions

Cell permeable: no
Primary Target
inactivates RNase
Product does not compete with ATP.
Reversible: no

Physical form

In 50 mM KCl, 20 mM HEPES, 8 mM DTT, 50% glycerol.

Preparation Note

Maintain at -20°C. Avoid freezing solutions. Addition of DTT is recommended to maintain 8 mM level.

Other Notes

One unit is defined as the amount of material that will inhibit 50% of the activity of 5 ng of RNase A.

Here, we describe a protocol to remove single identified cells directly from Drosophila living brains and analyze their transcriptome. We detail the steps to harvest fluorescent cells using a capillary under epifluorescence and transmitted light to avoid contamination. We then

RNA degradation is an essential process that allows bacteria to control gene expression and adapt to various environmental conditions. It is usually initiated by endoribonucleases (endoRNases), which produce intermediate fragments that are subsequently degraded by exoribonucleases (exoRNases). However, global studies
