Burch in their book The Principles of Humane Experimental Technique. The 3 R's are replacement, reduction, and refinement of the use of animals in research. The use of cell lines and tissue cultures that originated from research animals is a replacement technique, as it allows for many experiments to be conducted in vitro. Harvesting...

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN Many animal experiments rely on final data collection time points that are gathered from the harvesting and testing of organs and tissues. The use of appropriate methods for the collection of organs and tissues can impact the quality of the samples and the analysis of the data that is gleaned for the testing of the tissues. The method of euthanasia of the animal can also impact the quality of...

Drosophila melanogaster embryos and larvae are easy to manipulate and develop rapidly by mechanisms that are analogous to other organisms, including mammals. For these reasons, many researchers utilize fly embryos and larvae to answer questions in diverse fields ranging from behavioral to developmental biology. Prior to experimentation, however, the embryos and larvae must first be collected. This video will first demonstrate how "egg-laying cups" are used to collect Drosophila embryos on agar...

This technique exposes the Drosophila embryonic neuromusculature for immunohistochemistry or electrophysiological recording. It is useful for studying early events in neuromuscular development or performing electrophysiology in mutants that cannot hatch.
FAQs
Aseptic technique helps limit contamination introduced during tissue collection, which is important when specimens will undergo histopathology or molecular testing. By reducing unwanted biological material in the sample, it supports clearer interpretation and helps preserve the tissue’s suitability for analysis. This makes contamination control a central quality principle rather than merely a procedural preference.
Confirming the sampling plan aligns the intended tissue collection with the procedure, specimen handling, and planned analysis. It also establishes what must remain identifiable as the specimen moves through collection and labeling. This early coordination reduces avoidable uncertainty and supports consistent preparation across patient, donor, or experimental-subject procedures.
Anesthesia and hemostasis address subject protection while tissue is being collected. Coordinating them with the surgical preparation helps maintain appropriate conditions for the procedure and supports safe handling of the collection site. Their inclusion shows that specimen quality and procedural safety must be managed together, rather than treated as separate objectives.
Instrument and container selection should match the planned tissue collection and the need to preserve the specimen for analysis. Appropriate choices help maintain tissue identity and support handling after removal. Because different investigations may depend on architecture or molecular integrity, preparation must consider the specimen’s intended analytical use before collection starts.
Preparation begins by confirming the sampling plan, organizing the surgical field, and establishing aseptic conditions. The team then coordinates anesthesia and hemostasis, selects suitable instruments and containers, and prepares a labeling approach that preserves specimen identity. Together, these steps create an organized workflow for safe collection and reliable downstream analysis.
Accurate labeling preserves the relationship between a collected tissue sample and its planned source or procedure. This is essential because histopathology, molecular testing, and transplantation research depend on identifiable specimens. Labeling therefore contributes to interpretation as well as organization, helping ensure that analytical findings remain connected to the correct biological material.
This preparation is especially important when collected tissue will support histopathology, molecular testing, transplantation research, or other investigations requiring dependable biological specimens. Standardization helps preserve tissue architecture and molecular integrity while reducing contamination and protecting the subject. Its value extends across clinical collection, donor-related work, and experimental research settings.
