Lentiviruses are a valuable research tool for exploring gene function; however, researchers may wish to avoid production of pantropic lentivirus encoding known or suspected oncogenes. As an alternative, we present a safer protocol for use of ecotropic lentivirus on human cells modified to express the ecotropic receptor mSlc7a1.

Decontamination for Laboratory Biosafety
0 Views •
2023
Robert M. Rioux and Zhifeng Chen, Pennsylvania State University, University Park, PA Decontamination is essential for laboratory biosafety, as the accumulation of microbial contamination in the laboratory can lead to the transmission of disease. The degree of decontamination can be classified as either disinfection or sterilization. Disinfection aims to eliminate all pathogenic microorganisms, with the exception of bacterial spores on lab surfaces or equipment. Sterilization, on the other hand,...

Work with infectious Ebola viruses is restricted to biosafety level 4 laboratories. Tetracistronic minigenome-containing replication and transcription-competent virus like particles (trVLPs) represent a lifecycle modeling system that allows us to safely model multiple infectious cycles under biosafety level 2 conditions, relying exclusively on Ebola virus components.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
FAQs
Risk assessment determines which safeguards are appropriate for a particular activity by identifying biological hazards before work begins. The assessment then informs choices about containment, engineering safeguards, personal protective equipment, decontamination, and laboratory procedures. Because experiments and technologies can change, repeating this evaluation helps a laboratory adjust controls rather than relying on a fixed set of precautions.
Layered controls reduce dependence on any single protective measure. Containment and facility features provide one barrier, engineering safeguards add another, and personal protective equipment, decontamination, and standardized procedures reinforce the system during routine work. This arrangement matters because biosafety enhancement addresses accidental exposure and unintended release through coordinated protections, making weaknesses in one layer less likely to compromise the entire operation.
Training translates written procedures into consistent laboratory behavior, while incident response prepares personnel to act when an unwanted event occurs. Compliance provides an additional structure for maintaining those expectations over time. Together, these elements make biosafety enhancement an ongoing management process rather than a one-time equipment upgrade, supporting safer work and more dependable biological research.
An enhancement program can begin by reviewing the hazards associated with planned biological work, followed by selecting suitable containment, engineering safeguards, personal protective equipment, decontamination practices, and standardized procedures. Personnel then need training in the updated approach, with incident response included. Periodic review is important so controls remain aligned with changing experiments, technologies, and potential risks.
Equipment and facilities should be considered together with work practices, because physical safeguards alone do not replace appropriate procedures or personal protective equipment. Decontamination adds control after handling biological materials, while standardized methods guide how work is performed. Evaluating these components as a coordinated package helps laboratories protect personnel and limit effects beyond the immediate work area.
In biology research, biosafety enhancement is relevant wherever work involves microorganisms, cell cultures, or other biological materials. Its value extends beyond the individual researcher: controls are intended to protect personnel, communities, and the environment. Applying the approach also supports reliable experimental work because consistent procedures, training, and review help laboratories respond to changing biological risks.
