Drosophila Egg Collection and Dechorionation: A Method to Remove the Outermost Egg Layer
0 Views •
2023
The Drosophila embryo is surrounded by protective outer membranes. To gain access to the embryo, the chorion–the outermost of the membranes–is often removed. This video describes a commonly used method of dechorionation using sodium hypochlorite. The example protocol demonstrates the procedure while employing sterile techniques necessary for axenic or gnotobiotic animal rearing.

We demonstrate the effect of scleral crosslinking with riboflavin and UVA on an axial elongation rabbit eye. Axial elongation was induced in 13 day-old New Zealand rabbits (male and female) by suturing their right eye eyelids (tarsorrhaphy).

Optimized procedures for the isolation of single follicles, cytoplasmic RNA microinjections, the removal of surrounding cell layers, and protein expression in Xenopus oocytes are described. In addition, a simple method for fast solution changes in electrophysiological experiments with ligand-gated ion channels is presented.

The creation of functional microtissues within microfluidic devices requires the stabilization of cell phenotypes by adapting traditional cell culture techniques to the limited spatial dimensions in microdevices. Modification of collagen allows the layer-by-layer deposition of ultrathin collagen assemblies that can stabilize primary cells, such as hepatocytes, as microfluidic tissue models.

Thin-Layer Chromatography - Concepts

2020
Chromatography Chromatography is a technique used in organic chemistry to separate compounds in a mixture based on their differences in solubility between two different phases. The concept is similar to liquid-liquid extraction, except in chromatography, the two phases consist of the stationary phase and the mobile phase. The stationary phase is a solid — typically a microscale hydrogel bead — while the mobile phase is a carrier solvent. In traditional chromatography, the stationary phase is...
FAQs
The sclera is tough, while the choroid and retina beneath it are delicate. Cutting too deeply or peeling with excessive force can disturb the very layers the dissection is intended to expose. Controlled handling preserves tissue organization and improves the reliability of subsequent observation, imaging, or processing, particularly when researchers need to examine retinal structure rather than dissection damage.
Because the sclera is opaque, it can obstruct direct examination of the choroid and retina. Its removal opens the specimen so these underlying layers can be observed more directly and prepared for microscopy or imaging. This access helps investigators evaluate the spatial arrangement of ocular tissues and inspect features that would otherwise remain concealed beneath the outer coat.
The key relationship is the separation between the sclera, choroid, and retina. The outer coat must be removed without disrupting the attachment or organization of the deeper layers more than necessary. Preserving these neighboring tissues maintains meaningful anatomical context, allowing observations to reflect tissue organization rather than changes introduced during specimen preparation.
Once the opaque outer layer has been removed, researchers can examine the exposed choroid and retina more directly for disease-related changes. The technique does not by itself identify a disease, but it improves access for visual inspection, imaging, or additional processing. That makes it useful when structural alterations in retinal or surrounding ocular tissue are the focus.
The procedure begins with careful cutting of the scleral coat, followed by controlled peeling to separate it from the choroid and retina. Throughout the process, handling is adjusted to limit injury to the exposed layers. After separation, the specimen can undergo direct observation, imaging, or further processing according to the biological question being investigated.
The prepared specimen can provide clearer access for observing ocular anatomy, examining retinal structure, and assessing tissue organization. It may also be suitable for microscopy, imaging, or later processing. The value of the outcome depends on maintaining the underlying layers during removal, since damage can reduce the quality and interpretability of structural observations.
Scleral Layer Removal is useful when learners or researchers need direct access to tissues normally hidden by the eye’s outer coat. In teaching laboratories, it supports examination of ocular anatomy and tissue relationships. In vision research, the same access can aid retinal studies, imaging, and investigation of disease-related structural changes.
