Newcomer Supply Toluidine Blue Stain 0.1%, Aqueous, 500 ml

Use: Mast cell stain and MOHS basal cell carcinoma. Newcomer Supply Toluidine Blue Stain for Mast Cells is for the demonstration of mast cells, characterized as cells filled with basophilic granules, associated with inflammation and allergic reactions, which stain metachromatically with toluidine blue. Newcomer Supply Toluidine Blue Stain for Mohs Technique provides a rapid staining method for Mohs micrographic surgery (MMS), useful when evaluating frozen skin samples for basal cell carcinoma (BCC). Toluidine Blue imparts an identifiable staining pattern if BCC is present that will highlight islands of blue staining basal cell carcinoma and metachromatically stain surrounding mucopolysaccharides/stroma pink. Shelf Life is 1 year from date of manufacture. Store at 15-30°C.

AnaSpec Thioflavin T UltraPure Grade, | MW 318.9 | (1 g)

Thioflavin T *UltraPure Grade*, ; MW 318.9; (1 g) The benzothiazole dye thioflavin T (ThT) is a classic amyloid stain for senile plaques containing bA4 peptide in Alzheimer's disease brain. ThT also binds rapidly and specifically to the anti-parallel b-sheet fibrils formed from synthetic b-amyloid (1-40), but does not bind to monomer or oligomeric intermediates. The fibrillar b-sheet-bound dye species undergoes a characteristic 120 nm red shift of its excitation spectrum that may be selectively excited at 450 nm, resulting in a fluorescence signal at 482 nm. ThT is a useful probe for the aggregated fibrillar state of b-amyloid (1-40) fibrils as the amyloid-specific fluorescence reports only fibrillar species. The binding of ThT does not interfere with the aggregation of this peptide into amyloid fibrils. The putative conformational changes detected by the ThT fluorescence suggest that small pharmacologic ligands can perturb and possibly dissociate Ab amyloid fibrils.

Dojindo Molecular Technologies Inc Mtphagy Dye (5UG x3) is optimized for mammalian cells. No need for transfection, simply add Mtphagy Dye!

Mitochondria plays a crucial role in cells such as production of energy for cell viability. Mitophagy was recently found to be related to Alzheimer and Parkinson disease induced by the accumulation of depolarized mitochondria. Mitophagy serves as a specific elimination system that dysfunctional mitochondria caused by oxidative stress and DNA damage are sequestered into autophagosomes, fused to lysosomes and degraded by digestion. Mtphagy Dye accumulates in intact mitochondria, is immobilized on it with chemical bonds and exhibits a weak fluorescence from the influence of surrounding conditions. When Mitophagy is induced, the damaged mitochondria fuses to lysosomes and then Mtphagy Dye emits a high fluorescence.
