Medchemexpress LLC Patent blue V calcium salt | 3536-49-0 | 100.0% | 580.72 | 500 MG

Patent Blue V calcium salt is a triarylmethane dye for tissue staining and lymphatic tracing. Administered via topical injection or eye drops, it stains specific tissues like corneal endothelium and the lymphatic system to aid precise surgical operations. It finds application in ophthalmic surgery and sentinel lymph node biopsy for tumors. It's a potential alternative to Trypan blue for DMEK graft staining. Staining results are detectable by UV-visible spectrophotometry or fluorescence spectroscopy.

Alkali Scientific Trypan Blue, 100 G

Trypan Blue, 100g is a vital dye commonly used in cell viability assays, particularly for staining dead cells. The dye is able to penetrate the membranes of dead cells, but live cells with intact membranes exclude the dye, making it a useful marker in biological studies to distinguish between living and non-living cells. It is frequently used in cell culture experiments to assess cell mortality after treatment with toxic substances. The 100g pack size is suitable for laboratories conducting large-scale studies or those requiring a substantial quantity of dye for repeated testing. This reagent is critical in cell viability research, particularly in evaluating cytotoxicity and drug testing.
