Description générale

Trypan Blue is a tetrasulfonated anionic, hydrophilic azo dye derived from toluidine. The non-permeable cell membrane dye is a vital dye that selectively stains dead or non-viable cells, that pass through damaged but not through intact cell membranes.

Application

Trypan blue applications include:
  • it is a routinely used for viability testing for diverse cell types including frozen sperm and aortic muscle cells exposed to antifungal agents.
  • employed as a collagen stain in a Van Gieson procedure
  • To stain amyloid, Trypan blue is considered as a blue alternative to Congo red in Puchtler-Bennhold stains.
  • used as a fluorescent tracer of cell populations in embryology
  • used as a tumor promoter modulating permeability of lysosomal membranes
Trypan Blue solution has also been used in the cytotoxity tests and to determine the vital cells for the analysis of cell division.

Actions biochimiques/physiologiques

Trypan Blue is excluded by most living cells, but can be taken into phagocytes and certain other cells.

Alveolar macrophages (AM) in the lung have been documented to play pivotal roles in inflammation and fibrosis (silicosis) following inhalation of crystalline silica (CSiO(2)). In contrast, exposure to either titanium dioxide (TiO(2)) or amorphous silica (ASiO(2)) is considered relatively benign.

Exosomes are microvesicles of endosomal origin that are secreted, and their contents (proteins, lipids, DNA, or microRNAs) can alter the physiological states of recipient cells. We demonstrated that phosphatase and tensin homolog deleted on chromosome 10 (PTEN), a tumor suppressor

A fundamental question in biology is how multicellular organisms distinguish self and non-self. The ability to make this distinction allows animals and plants to detect and respond to pathogens without triggering immune reactions directed against their own cells. In plants

Head and neck squamous cell carcinomas (HNSCC) are frequently drug resistant and have a mortality rate of 45%. We have previously shown that E2F7 may contribute to drug resistance in SCC cells. However, the mechanism and pathways involved remain unknown.
