Scientific Data Examples for Recombinant S. marcescens NucA Protein, CF

	NucA (Benzonase) Digestion of DNA. 2 μg plasmid DNA was incubated with increasing amounts (ng/mL) of RecombinantS. marcescensNucA (Benzonase) (Catalog # 10038-NA) in 50 mM Tris (pH 8.0) and 1 mM MgCl2 for 30 minutes at room temperature. Samples were analyzed by agarose gel electrophoresis and DNA was visualized by ethidium bromide staining.

Formulation, Preparation and Storage

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: Benzonase® Nuclease/NucA

Serratia marcescens endonuclease, also known as Benzonase, is a non-specific nuclease that degrades both single- and double-stranded nucleic acids, including DNA and RNA, but exhibits no proteolytic activity (1); therefore, it is ideal for the removal of nucleic acid contaminants from protein samples and applications where complete digestion of nucleic acids is desirable. NucA (Benzonase) is also commonly used in bioprocessing applications to reduce viscosity of samples caused by genomic DNA. The optimum pH for enzyme activity is found to be 8.0-9.2. It hydrolyzes internal phosphodiester bonds between nucleotides in nucleic acids to produce 5'-monophosphate oligonucleotides of 3-8 bases in length (2). The active enzyme is a homodimer with two disulfide bonds in each monomer that are crucial to the enzyme activity and stability (3). The absolute activity of the recombinant enzyme is measured by a phosphatase coupled assay (4), where the 5'-phosphate of oligosaccharides generated by the enzyme is further released by non-specific alkaline phosphatase and quantitated by Malachite reagents (5).
