Features and Benefits

Nuestra muy estable ribonucleasa A, ARNasa A, es idónea para la eliminación del ARN, la secuenciación del ARN y la purificación del ADN.

General description

La ARNasa, ribonucleasa A, es una endorribonucleasa que escinde los enlaces fosfodiéster del ARN monocatenario después de nucleótidos de pirimidina. Ataca el extremo 3′ fosfato (por ejemplo, el pG-pG-pC-pA-pG será escindido para dar pG-pG-pCp y A-pG). La mayor actividad la exhibe con ARN monocatenario. La ARNasa A es un polipéptido monocatenario que contiene cuatro puentes bisulfuro. Al contrario que la ARNasa B, no es una glucoproteína. Las ribonucleasas no hidrolizan el ADN porque el ADN carece de los grupos 2′-OH esenciales para la formación de los intermediarios cíclicos. La ARNasa A también puede hidrolizar el ARN de las muestras proteicas. La ARNasa A puede ser inhibida por alquilación de la His12 o la His119 y activada por sales de potasio y de sodio. La RNAasa se inhibe en presencia de iones de los metales pesados. La ARNasa también es inhibida competitivamente por el ADN.
RNase A is an endoribonuclease that attacks at the 3′OHphosphate of a pyrimidine nucleotide. The sequence of pG-pG-pC-pA-pG will be cleaved to give pG-pG-pCp and A-pG. The highest activity is exhibited with single stranded RNA.

Other Notes

A major application for RNase A is the removal of RNA from preparations of plasmid DNA. For this application, DNase free RNase A is used at a final concentration of 10 ug/mL.

Boiling stock solutions of this RNase A product to inactivate residual DNase is not necessary and may cause precipitation of RNase and possible loss of enzymatic activity. If an RNase A solution is heated at a neutral pH, precipitation will occur. When heated at a lower pH, some precipitation may occur because of protein impurities that are present.
Activators of RNase A include potassium and sodium salts. RNase A can be inhibited by alkylation of His12 or His119.
RNase A is supplied as a solution of 50% glycerol containing 10 mM Tris-HCl (pH 8.0).

  8. Why is RNase A activity not listed as micromoles per minute, and what is a Kunitz unit?

    The Kunitz unit was created to reflect the non-linear nature of the RNAse enzymatic reaction. As the reaction progresses the activity changes due to RNA as a heterogeneous polymeric substrate; therefore, the unit of moles or micomoles per minute becomes inaccurate. As such, our enzymatic assay describes a unit that varies throughout the reaction: One unit will cause a decrease of 100% per minute in the value of E0 - Ef at pH 5.0 at 25°C. Ef is determined in the RNAse control step, while E0 reflects the current reaction rate.
