are separated from their mother and given orally or orogastrically the test material in a volume of 50μl or less. Addition of 1μl of a solution of 2%Evans blueis used as a tracer dye to ascertain the proper administration of the sample. The animals are kept at 25°C for 2h and ...
Evaluation of preparations of patent blue (Alphazurine 2G) dye for parenteral use The stability and the behavior of patent blue (Alphazurine 2G) dye in a vehicle such as lidocaine hydrochloride injection were studied with regard to medic... DW Newton,AG Rogers,CH Becker,... - American Jour...
TB in vitreoretinal surgery was initially proposed for injection after an air–fluid exchange, allowing for better dye dropping on to the retinal surface. To enhance dye penetration on to retinal surface in an air–fluid exchange, TB may be mixed with glucose at higher than 5%, for instance ...

Phycocyanin, a pigment found in spirulina species discussed earlier in this review, is the most stable natural dye for the blue shade. However, it is not permitted as a raw material for dye production in the US and EU. Spirulina sp. is classified by the FDA as a cyanobacterium and is co...
Therefore, the concentration of the dye is proportional to the number of metabolically active cells. XTT assays were carried out 24 h after the second light exposure. Reactive oxygen species (ROS) assay: For the ROS assay, cells were seeded at a density of 4500 cells/cm2 and incubated for...
One of the earliest and most common methods for measuring cell viability is the trypan blue staining assay. Trypan blue is an azo dye that is cell membrane impermeable and therefore only enters cells with compromised membranes. Upon entry into the cell, trypan blue binds to intracellular proteins...
