Trypan blue is so-called because it can kill trypanosomes, the parasites that cause sleeping sickness. An analog of trypan blue, suramin , is used pharmacologically against trypanosomiasis . Trypan blue is also known as diamine blue and Niagara blue.

Trypan Blue Solution, 0.4%, is routinely used as a cell stain to assess cell viability using the dye exclusion test. This test is often performed while counting cells with the hemocytometer during routine subculturing, but can be performed any time cell viability needs to …

Trypan blue is a dye used as a visualizing aid to stain the epiretinal membranes during ophthalmic surgical vitrectomy procedures, thereby facilitating the removal of the tissue. It is used in ophthalmic cataract surgery to stain the anterior capsule in the presence of a mature cataract.

Cells are suspended in PBS containing trypan blue and then examined to determine the percentage of cells that have clear cytoplasm (viable cells) versus cells that have blue cytoplasm (nonviable cells).

The trypan blue staining assay allows for a direct identification and enumeration of live (unstained) and dead (blue) cells in a given population. In this assay, a cell suspension is simply mixed with trypan blue and then visually examined to determine whether cells take up or exclude the dye.

Trypan blue (C.I. 23850) for microscopy, is a dry dye for the preparation of a color staining solution, staining histological sample material of human origin, e.g. trichrome staining in collagenous connective tissue. The dye has a constant dye content and a reliable high quality, which is one of the major precondition for a reproducible ...

Trypan Blue is an acid azo dye commonly used as a stain to distinguish viable from non-viable cells. It turns dead cells blue and viable cells unstained. It is a known animal carcinogen and an experimental teratogen.

Trypan blue is a stain used to quantify live cells by labeling dead cells exclusively. Because live cells have an intact cell membrane, trypan blue cannot penetrate the cell membrane of live cells and enter the cytoplasm. In a dead cell, trypan blue passes through the porous cell membrane and enters the cytoplasm.

2024年11月20日 · Trypan Blue is an azo dye used in cell viability assays to distinguish live and dead cells with its membrane exclusion mechanism. Trypan Blue leverages its ability to differentiate live and dead cells based on membrane integrity: viable cells with intact membranes exclude the dye and remain unstained, whereas non-viable cells with compromised ...
