Improved staining boxes for fast, uniform staining of ultrathin sections on grids

Abstract

A standard LKB (LKB-Produkter Ab. S-161, 25 Brommma 1, Sweden) grid storage box is converted into several grid staining boxes by sawing the body of the box into segments along rows of its grid storage cavities. The staining boxes can be cut out to any required size or shape. The polymethyacrylate storage box cover is discarded. Covers for the staining boxes are cut from thin sheet vinyl, which is more chemically resistant than polymethyacrylate. Corresponding 2 mm diameter holes are drilled through the vinyl covers and the bottoms of the grid storage cavities of the staining boxes to convert the storage cavities into staining chambers. For staining, the covers are tied to the boxes with sewing thread and the assembled units are put into vials. The separate staining chambers prevent intermingling of and mechanical damage to grids during the staining procedure. Ultrathin sections are more cleanly and uniformly stained in bulk by the use of these staining boxes than they are when stained individually by a standard method.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Autism: Motor Learning

A common feature of autism spectrum disorder (ASD) is the impairment of motor control and learning, consistent with perturbation in cerebellar function. Find the latest research on ASD and motor learning here.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration

Protein Localization in Disease & Therapy

Localization of proteins is critical for ensuring the correct location for physiological functioning. If an error occurs, diseases such as cardiovascular, neurodegenerative disorders and cancers can present. Therapies are being explored to target this mislocalization. Here is the latest research on protein localization in disease and therapy.

Genetic Screens in Bacteria

Genetic screens can provide important information on gene function as well as the molecular events that underlie a biological process or pathway. Here is the latest research on genetic screens in bacteria.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.
