Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University Genetic modification of foods has been a controversial issue due to debated concerns over health and environmental safety. This experiment demonstrates technical understanding of how food DNA is genetically identified, allowing for educated decision making about the safety and potential dangers of using genetically modified organisms (GMOs) in food supplies. Polymerase Chain Reaction (PCR) is used to amplify food DNA...

Modified Boxplots

A standard box and whisker plot informs us about the spread of the data in a given sample. One can identify the minimum value, maximum value, first quartile value, second quartile or median value, and third quartile. However, the box plot does not tell the reader about outliers - values that lie far from the center of the data. We can modify the standard box and whisker plot to identify the outliers and visualize the actual spread of the data in a sample. Initially, we calculate the adjusted...

This video demonstrates the process of transfecting primary macrophages with modified mRNA encoding green fluorescent protein. These modified mRNAs, designed to reduce immunogenicity and improve its stability, ensure the successful transfection and subsequent expression of green fluorescent proteins, which is confirmed through fluorescence microscopy.

A Phenotyping Regimen for Genetically Modified Mice Used to Study Genes Implicated in Human Diseases of Aging

A reverse-genetics approach to understanding gene families associated with human disease is presented, using mouse as a model system, and the subsequent mouse phenotyping schedule is described. Because mice defective in a gene of interest, HtrA2, manifested Parkinsonian symptoms, the phenotyping regimen is focused on identifying neurological defects.
FAQs
The handler controls movement by gently grasping the loose skin over the shoulders and neck rather than compressing the airway. Simultaneously supporting the body and hindquarters helps keep the mouse positioned and reduces uncontrolled motion. This balance allows brief biomedical interventions while preserving normal breathing and lowering the risk of handling-related injury.
Support beneath the body and hindquarters complements the skin hold and helps prevent the mouse from slipping, escaping, or struggling excessively. It also distributes control across the animal’s position instead of relying only on the neck and shoulder area. Consistent support therefore contributes to safer handling and more reliable positioning during short procedures.
Training helps the handler apply the technique consistently, while calm handling can reduce struggling during restraint. Fewer abrupt movements make it easier to maintain controlled positioning and avoid accidental injury. These factors also support animal welfare and improve procedural reliability, because the handler can perform the intended intervention with less disruption caused by escape attempts or excessive movement.
A trained handler should gently grasp the loose skin over the shoulders and neck, support the mouse’s body and hindquarters, and maintain positioning without compressing the airway. The grip should limit movement while allowing breathing to remain unrestricted. Calm, controlled execution is important throughout the brief intervention, followed by release when restraint is no longer needed.
The technique can facilitate physical examination, injections, dosing, and blood collection when controlled positioning is needed. It may also support other brief interventions in which movement could interfere with the procedure. Its value lies in helping the handler maintain a stable position while reducing escape, struggling, and handling-related injury risks.
In biomedical settings, consistent animal positioning can help handlers carry out brief interventions in a controlled manner. Modified Scruff Grip links practical restraint with two important outcomes: improved animal welfare and greater reliability of experimental procedures. Its usefulness depends on appropriate training, calm handling, body support, and protecting the airway during the intervention.
