We present a simple and efficient protocol for the generation of human macrophages. Buffy coats are processed by double density gradient centrifugation and isolated monocytes are then differentiated to macrophages in Teflon-coated cell culture bags. This maximizes macrophage yields and facilitates cell harvesting for subsequent experiments.

This video demonstrates a technique for generating antigen-specific chimeric antigen receptor (CAR) T cells through retroviral transduction. Activated murine CD8+ T cells are added to a microwell plate coated with recombinant fibronectin fragments. Retroviral vectors containing transgenic RNA encoding an antigen-specific chimeric antigen receptor (CAR) are then introduced, and the plate is centrifuged to facilitate transduction. After incubation, the transduced cells express antigen-specific...

We provide a technique to preserve intact tree phloem and prepare it for observation. We create an apparatus called a phloem sandwich that allows for the introduction and observation of arthropods, microbes, and other organisms that inhabit phloem tissues.
FAQs
Mesh bags hold a measured quantity of plant material while allowing field conditions to act on it. Their use creates a consistent enclosure in which moisture, temperature, and contact with decomposing organisms can influence the sample. Because the material remains contained, researchers can recover it at defined times and compare changes among environmental settings.
Temperature, water availability, soil conditions, and litter quality can all change the rate at which organic material decomposes. These factors influence microbial activity and the broader conditions experienced by decomposers. Comparing samples exposed to different habitats, seasons, or environmental treatments helps separate how each setting affects mass loss and the release of carbon and nutrients.
Different plant materials may decompose at different rates, so litter quality must be considered when comparing samples. A change in mass or composition reflects the combined influence of the material itself and the surrounding environment, including moisture and microbial activity. Using comparable starting materials, or accounting for their differences, strengthens interpretation of ecosystem-level decomposition patterns.
Researchers first dry and weigh a known mass of leaf litter or another organic material, then place it inside mesh bags. They position the bags under the selected field conditions and retrieve them at predetermined intervals. After collection, they measure remaining mass and assess composition, allowing decomposition to be compared across sampling times or environmental treatments.
Identically prepared bags can be placed in different habitats or deployed during different seasons, then collected according to a planned schedule. Measuring the remaining material and its composition provides comparable observations of decomposition under each condition. Differences among sites or periods can indicate how temperature, water availability, soil conditions, and other environmental factors shape ecosystem processes.
Changes in the mass and composition of enclosed plant material show how organic matter is processed over time. These observations connect decomposition with the release of carbon and nutrients, making the method useful for examining ecosystem function. In environmental studies, contrasting decomposition patterns helps researchers evaluate how local conditions influence nutrient cycling and related ecosystem processes.
