525 Results for: "xanthene hydride"

Supplier: Biotium

BCECF, AM ester is membrane-permeant and thus can be loaded into cells via incubation. This product is a mixture of three molecular species, all of which are readily hydrolyzed by endogenous esterases into a single BCECF free acid form once they are in the cells.

Supplier: Biotium

Membrane-permeant AM ester form of Fluo-3 that can be loaded into cells via incubation. Fluo-3 AM ester itself does not bind Ca2 , but it is readily hydrolyzed to Fluo-3 by endogenous esterases once the dye is inside the cells. An important application of Fluo-3 AM ester is its use in high throughput drug screening.

Useful in tests for urea

Supplier: Biotium

Membrane-permeant AM ester form of Fluo-3 that can be loaded into cells via incubation. Because of the relatively low water solubility of the AM ester, the mild detergent Pluronic F-127 (catalog no. 59004) is often used as a dispersing agent to facilitate loading. Fluo-3 AM ester itself does not bind Ca2 , but it is readily hydrolyzed to fluo-3 by endogenous esterases once the dye is inside the cells. An important application of Fluo-3 AM ester is its use in high throughput drug screening.

These HPLC columns have a silica hydride surface similar to other TYPE-C™ phases with all the TYPE-C silica benefits. The value of Phenyl Hydride™ is that they have unique selectivity for compounds with aromatic rings and because of the direct silicon carbon bonds, these columns are extremely stable with long column lifetime. These columns can be used in Reversed Phase (RP), Aqueous Normal Phase (ANP) or Normal Phase (NP) and changed back and forth without damage to the columns.
