Item #: SCP-3296
Class: Keter
Special Containment Procedure: SCP-3296 must be contained in any biological organism, preferably Caucasian females1 currently exhibiting a mutation that leads to an inhibited TP53, INK4 or PTEN tumor suppression gene. Due to the nature of SCP-3296, blood must be collected from the biological organism currently holding SCP-3296 every 20 weeks and transfused into the newly appointed carrier. SCP-3296-1 is to be contained in a non-permeable organic containment made of a double lipid bilayer with a fortification of a calcium ion gradient. SCP-3296-1 is to be kept in a vegetative coma and must be connected to life-support systems at all time. All metabolic activity is to be monitored 24/7 and any change must be reported to a supervising researcher assigned with tracking and maintaining SCP-3296 and SCP-3296-1. Any decay or breakdown of the containment of SCP-3296-1 must be reported to the supervising researcher and SCP-3296-1 must be atomized right away. Two vials of blood containing SCP-3296 must be kept in a container made of the same organic material as the quarantine for SCP-3296-1 and kept at standard body temperature. After the death of SCP-3296-1, a D-Class subject must be brought in and given the blood containing SCP-3296 and placed in a vegetative coma. Two vials of blood must be taken from each new subject.
Note: In the unlikely event of the sudden death, SCP-3296-1 must be atomized immediately in order to prevent the diffusion of SCP-3296 into the facility.

Description: SCP-3296 is a standard free radical atom of oxygen but due to unknown anomalous properties displays an increased effect on the damage of cells and DNA. Instead of taking electrons from nearby atoms and incorporating them into itself as a standard free radical would, SCP-3296 destroys electrons in the atoms surrounding it, thus creating a never-ending chain of free radicals. If left alone, SCP-3296 will convert all atoms in a biological organism into other copies of itself, thus permanently destroying DNA and sending the biological organism carrying SCP-3296 into complete organ failure within minutes of exposure. See addendum A. When exposed to dead biological tissue, SCP-3296 begins to expand and flow in accordance to gaseous properties and diffuse through any source (except the non-permeable gradient mentioned in the containment procedures). When gaseous SCP-3296 is exposed to living tissue, it will convert all other atoms into free radicals unless the TP53, INK4 or PTEN tumor-suppressing genes are inhibited. If SCP-3296 comes into contact with biological tissue mutated to suppress at least one of these genes, it will function as a regular free-radical, with the only difference of rejecting antioxidants.

SCP-3296 exhibits favorable effects in subjects with the suppression of the tumor-suppressor genes listed above. The seemingly unstoppable cell division would not form malignant tumors, but rather growths that serve no adverse properties. An increased rate of apoptosis is seen and any malignant tumors are destroyed. The subject is able to survive for 20 minutes (a vegetative coma state allows for an average survivability time of 21 weeks) before the growths cover vital organs and prevent air and blood flow throughout the body. There is currently no way to destroy SCP-3296. Although atomization has proven to be successful in suppressing SCP-3296 long enough to repair its containment, it activates after five hours of dormancy, or when exposed to biological tissue.

Addendum A: Experiment Logs

Experiment 1
Subject: D-19876, male, 22, no signs of mutated tumor-suppressor genes or any detrimental mutation of any kind.
Researcher: Dr. ██████
Test: Expose D-19786 to SCP-3296 through blood transfusion while inside the specified containment. Monitors were hooked up to D-19786 to measure metabolic activity and reading. Further D-Class personnel exposed to SCP-3296 will be referred to as SCP-3296-1.
Result: SCP-3296-1 reported to feel nauseated and feverish two minutes into the test. Four minutes into the test SCP-3296-1 fell over and complained of intense abdominal pain; monitor feedback displayed high internal temperatures reaching 41 degrees Celsius (107.6 degrees Fahrenheit). Six minutes into the test SCP-3296-1 began to experience convulsions and minor seizures as a presumed result of SCP-3296 attacking the brain and nervous system. Monitors revealed an extremely high heart rate and blood pressure. Ten minutes into the test SCP-3296-1 flatlined and was immediately atomized as to not illicit the gaseous spread of SCP-3296 throughout the containment facility. SCP-3296 was retrieved through the use of a carbon monoxide lined magnet. Atomic microscope readings revealed SCP-3296 was successfully picked up, and SCP-3296 was contained safely.

Note: Bits of DNA were found after the atomization of SCP-3296-1 and were seen to be completely destroyed. It was concluded that SCP-3296 destroys DNA by tearing the base pairs apart from their complementary letter. It is not currently known why the DNA backbone is left intact.

Experiment 2
Subject: D-23421, male, 23, extreme mutation of two tumor-suppressing genes (INK4 and PTEN), and stage 4 liver cancer.
Researcher: Dr. ██████
Test: Expose D-23421 to SCP-3296 through blood transfusion while inside the specified containment. Monitors were hooked up to D-23421 to measure metabolic activity and reading.
Result: Two minutes into the test, metabolic readings revealed an extreme rate of apoptosis in the cells and the destruction of SCP-3296-1’s malignant liver cancer. Four minutes into the test, SCP-3296-1 no longer had liver cancer, and was free of any other malignant growths that started to appear before the test. Six minutes into the test, SCP-3296-1 began to exhibit mass amounts of growth both internally and externally all throughout the upper body and feet. Ten minutes into the test, SCP-3296-1 reported difficulty breathing and swallowing. This was seen to be due to the mass amounts of growths sprouting around the esophagus and trachea. 15 minutes into the test SCP-3296-1 fell over and asphyxiated due to the complete covering of his esophagus and trachea. SCP-3296-1 was atomized and SCP-3296 was retrieved using a carbon monoxide lined magnet.

Note: It is not known why SCP-3296 has this effect on subjects with the mutated tumor suppressor genes but further testing is not needed unless deemed necessary by two-thirds of the O5-council.
