Micrococcal nuclease
Based on 1 Customer Validation
Micrococcal nuclease is a secreted nuclease from Staphylococcus aureus. It digests single-stranded and double-stranded DNA (ssDNA and dsDNA) as well as RNA, cleaves oligonucleotide linkers with T-T sites, and cuts neutrophil extracellular traps and biofilm extracellular DNA into mononucleotides and dinucleotides. Micrococcal nuclease stimulates the formation of Staphylococcus aureus biofilms and mediates immune evasion. It triggers on-demand release of antibiotics from hydrogel coatings, prolongs the formation of neutrophil extracellular traps, and promotes the dissemination and survival of MRSA during infection. Micrococcal nuclease is applicable to research and characterization related to Staphylococcus aureus infection.

Biological Activity
Micrococcal nuclease (24 h) cleaves unmodified oligonucleotide linkers (0PS) faster than phosphorothioate-modified linkers (6PS), thereby releasing ampicillin and resulting in larger bacterial growth inhibition zones on S. aureus Xen29 agar cultures[2].
Micrococcal nuclease (derived from *Staphylococcus aureus* Newman WT lux) increases the bacterial density of biofilms on hydrophilic surfaces to 0.5 bacteria/mm3[3].
Micrococcal nuclease (24 h) cleaves unmodified 0PS oligonucleotide linkers faster than phosphorothioate-modified 6PS linkers, resulting in a higher amount of ampicillin released from hydrogel coatings[2].

Animal Model:Balb/c OlaHsd (female, 4-5 weeks old, average weight 20 g, subcutaneous implantation of polyvinylidene fluoride mesh followed by *Staphylococcus aureus* inoculation)[3]
-
Dosage:Endogenous production via inoculated S. aureus Newman WT lux (108 CFUs)
-
Administration:subcutaneous injection at implant site; single dose; day 0
-
Result:Showed significantly higher bioluminescence (bacterial load) from day 1 to day 7 compared to nuclease-deficient mutant group, with no significant 3- to 10-fold signal decrease.
Recovered significantly more CFUs from mesh-tissue samples at day 7 compared to nuclease-deficient mutant group.
Displayed significantly higher S. aureus levels, myeloperoxidase levels, and citrullinated histone levels at day 7, with biofilms detected at the mesh-tissue interface.
Detected bacterial biofilms at the mesh-tissue interface at 12-13 days, with myeloperoxidase and citrullinated histones colocalized with biofilm structures.
Detected no foreign body giant cells in samples at either 7 or 12-13 days.
