Necrotizing enterocolitis (NEC) is the most severe gastrointestinal (GI) disease that often occurs in premature infants, especially very low birth weight infants, with high mortality and unclear pathogenesis. The cause of NEC may be related to inflammatory immune regulatory system abnormalities. An NEC animal model is an indispensable tool for NEC disease immune research. NEC animal models usually use C57BL/6J neonatal mice; BALB/c neonatal mice are rarely used. Related studies have shown that...

Multiphoton microscopy of whole mouse organs is possible by optically clearing the organ before imaging, but not all protocols preserve the fluorescent signal of fluorescent proteins. Using an optical clearing method with ethanol-based dehydration and benzyl alcohol:benzyl benzoate clearing, we show high-resolution multiphoton images of whole mouse brain expressing YFP.

We present a protocol for the analysis of coronary vessels in whole embryonic murine hearts up to E15.5, using standard immunological staining methods followed by optical clearance and confocal microscopy. This technique enables visualization of blood vessels throughout the entire heart without the need for time-consuming analysis of serial sections.
FAQs
The key optical effect is reduced light scattering. After water in fixed tissue is replaced by the benzyl alcohol and benzyl benzoate mixture, the surrounding solvent more closely matches the refractive index of cellular components. Light therefore encounters fewer optical mismatches as it travels through the specimen, improving transparency and optical access for microscopy, especially in thicker samples.
Benzyl alcohol and benzyl benzoate function together as the organic solvent mixture used with fixed tissue. Their relevant contribution is not a biological stain or genetic label; they replace water in the specimen and create an optical environment closer to cellular material. That shared solvent action supports transparency, allowing microscopy to access structures that remain difficult to resolve when tissue scatters light.
Clearing can improve optical access to fluorescently stained or genetically labeled tissue, but the solvent treatment may also affect fluorescent signals. Consequently, transparency and signal preservation must be considered together rather than treating improved visibility as guaranteed preservation of labeling. This balance matters when interpreting three-dimensional images, because a clearer specimen may still show altered fluorescence after processing.
A BABB-based workflow can begin with fixed tissue, followed by fluorescent staining or use of genetic labeling when those signals are needed. The specimen is then exposed to the benzyl alcohol and benzyl benzoate mixture to replace water and improve optical access before microscopy. This sequence supports imaging of labeled structures in three dimensions, provided solvent toxicity and signal effects are considered.
Embryos, organs, and other labeled tissues are identified applications for BABB clearing. These specimens can contain structures that are difficult to resolve while opaque, so reducing scattering helps microscopy reveal their spatial organization. The approach is particularly relevant when researchers need optical access through a specimen rather than only a view of structures readily visible at its exterior.
By reducing scattering and improving optical access through the specimen, BABB processing can support three-dimensional imaging of structures within biological samples. In embryos, organs, or labeled tissues, this can help reveal spatially distributed features and relate fluorescent or genetically defined signals to their location within the specimen, expanding observation beyond structures that are difficult to resolve in opaque tissue.
