A solvent is a substance, most often a liquid, that can dissolve other substances. Here, the substance being dissolved is called a solute. When a solvent and a solute combine, they form a solution - a homogenous mixture of both the solvent and the solute. Water is a universal biological solvent. Its polar structure allows it to dissolve many other polar compounds. The ability of water to dissolve is governed by a balance between water molecules binding to each other and binding to the solute. A...

Rotary Evaporation to Remove Solvent

Source: Dr. Melanie Pribisko Yen and Grace Tang — California Institute of Technology Rotary evaporation is a technique most commonly used in organic chemistry to remove a solvent from a higher-boiling point compound of interest. The rotary evaporator, or "rotovap", was invented in 1950 by the chemist Lyman C. Craig. The primary use of a rotovap is to dry and purify samples for downstream applications. Its speed and ability to handle large volumes of solvent make rotary evaporation a preferred...

Source: Hsin-Chun Chiu and Tyler J. Morin, laboratory of Dr. Ian Tonks—University of Minnesota Twin Cities Schlenk lines and high vacuum lines are both used to exclude moisture and oxygen from reactions by running reactions under a slight overpressure of inert gas (usually N2 or Ar) or under vacuum. Vacuum transfer has been developed as a method separate solvents (other volatile reagents) from drying agents (or other nonvolatile agents) and dispense them to reaction or storage vessels while...

2016
A new way for the production of biopolymer-based aerogels by carbon dioxide (CO2) induced gelation is shown. The technique utilizes pressurized carbon dioxide (5 MPa) for the production of biopolymer hydrogels and supercritical CO2 (12 MPa) to convert gels into aerogels. The only solvents needed besides CO2 are water and ethanol.
FAQs
Embryo permeation solvent improves access by modifying lipid-rich membranes and extracellular spaces, which can otherwise limit movement through embryonic tissue. This change allows dyes, antibodies, nucleic acid probes, and related reagents to diffuse toward their targets. Effective access supports labeling throughout the embryo rather than only at exposed surfaces.
The solvent’s concentration and exposure time must be matched to the tissue and assay. Insufficient treatment may leave barriers that restrict reagent diffusion, whereas excessive permeation can damage embryonic morphology or weaken signal quality. Optimization therefore requires balancing molecular access against preservation of structure, especially when microscopy depends on both labeling intensity and anatomical detail.
Membrane and extracellular-space changes matter because they determine whether a reagent can move through the embryo to reach its intended target. Dyes and antibodies provide labeling, whereas nucleic acid probes support molecular detection. The solvent therefore influences assay accessibility, while the reagent determines what biological feature becomes visible or detectable.
In whole-mount workflows, Embryo Permeation Solvent is used to facilitate reagent entry during preparation for microscopic analysis. Researchers control its concentration and exposure time, then apply or evaluate dyes, antibodies, or nucleic acid probes for staining or detection. The workflow aims to improve access throughout the specimen while retaining the embryo’s structure.
Improved permeation supports several complementary assays, including whole-mount staining, immunolabeling, and in situ hybridization. Stains and antibodies help visualize labeled structures, while nucleic acid probes support detection of molecular targets such as gene expression patterns. Together, these applications allow researchers to examine signals across embryonic tissues while maintaining their spatial relationship.
Successful treatment can produce interpretable patterns of dye, antibody, or probe distribution across embryonic tissues. These patterns help investigators examine gene expression and tissue organization while retaining morphological context. If permeation is too strong, however, structural damage or reduced signal quality can make molecular findings harder to interpret.
