Descripción general

Neutral red is a vital dye widely used as a cellular pH indicator and is selective for shifts in pH. It is highly lipophilic in nature. It favours membrane potential dependent fluorescence that attributes to changes in hydrophobicity.

Aplicación

Neutral red has been used to stain mouse mammary glands.
Useful as an indicator for preparing neutral red paper, and as a biological stain.

Whole mount preparations of mouse mammary glands are useful for evaluating overall changes in growth and morphology, and are essential for detecting and evaluating focal or regionally-localized phenotypes that would be difficult to detect or analyze using other techniques. We

Microalgae are common members of the atmospheric microbial assemblages. Diverse airborne microorganisms are known to produce ice nucleation active (INA) compounds, which catalyze cloud and rain formation, and thus alter cloud properties and their own deposition patterns. While the role

The intact vaginal epithelium is essential for women's reproductive health and provides protection against HIV and sexually transmitted infections. How this epithelium maintains itself remains poorly understood. Here, we used single-cell RNA sequencing (RNA-seq) to define the diverse cell populations
