Filamentous actin (F-actin) plays an important role in spinogenesis, synaptic plasticity, and synaptic stability. Quantification of F-actin puncta is therefore a useful tool to study the integrity of synaptic structures. This protocol describes the procedures of quantifying F-actin puncta labeled with Phalloidin in low-density primary cortical neuronal cultures.

Fluorescence in-situ hybridization (FISH) is often required in combination with histopathology and molecular diagnostics for selection of therapy in personalized medicine. A novel non-cross-linking, formalin-free tissue fixative that allows high quality morphologic, molecular and FISH analyses from the same specimen by addition of a post-fixation step before FISH is presented.
FAQs
Its core mechanism is the association of each specimen identifier with descriptive and operational metadata. The map can connect tissue or fluid type, anatomical source, collection conditions, processing history, storage location, and experimental status, allowing users to interpret a sample in context rather than as an isolated record. This linkage supports systematic selection and comparison across a collection.
Metadata quality directly affects what the map can reveal. Recording collection conditions and processing history helps distinguish specimens that may otherwise appear equivalent, while anatomical source and material type clarify biological comparability. Storage location and experimental status add operational context. Together, these fields help investigators identify suitable samples, recognize incomplete coverage, and detect sampling gaps or biases.
Unlike a simple list that primarily indicates whether materials exist, a Biospecimen Map preserves relationships among specimens, their origins, and associated study information. Its visual or digital structure can show how samples connect across a collection or project, making it easier to integrate physical materials with molecular, clinical, or spatial analyses and to trace relevant context during interpretation.
Building one starts with a consistent identifier for every specimen, followed by recording the fields needed to describe its biological origin and handling. Those fields include material type, anatomical source, collection conditions, processing history, storage location, and experimental status. Organizing them into a visual or digital structure then creates a usable basis for tracking, selection, and interpretation.
Biobanking and sample tracking are central use cases because the map links a specimen's identity to where it came from, how it was handled, and where it is stored. During study design, investigators can use the organized view to select appropriate materials and recognize gaps or biases in the available collection. Quality-control activities also benefit from the shared context.
The map can connect physical specimens with molecular, clinical, or spatial analyses by preserving the sample context needed to interpret those results. This connection supports data integration and reproducibility: investigators can relate an analysis to specimen origin, handling history, and study status instead of treating the result as independent of the material examined. It is especially useful when combining information across a project.
