Overview

Product description:

U-73343, works as a protonophore, is an inactive analog of U-73122 and can be used as a negative control. U-73343 dose-dependently inhibits acid secretion irrespective of the stimulant. U-73122 is a phospholipase C (PLC) and 5-LO (5-lipoxygenase) inhibitor with an IC50 of 1-2.1 µM for PLC。


Application:

U-73343 has been used for studying the role of phospholipase C (PLC) signaling in modulating epithelial Na+ channel (ENaC) function in gerbil Reissner′s membranes (RMs). U-73343 has also been used as a negative control for PLC inhibition in mechanically stimulated (MS) and its neighboring (NB) cells.

U-73343 has been used in measuring the fluorescence of intracellular Ca2+.

Note
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
