ReadiUse™ probenecid, sodium salt

Water-soluble

ReadiUse™ probenecid, sodium salt is a water-soluble organic anion transporter inhibitor used to improve intracellular retention of fluorescent indicators in cell-based assays.

Mechanism: Inhibits organic anion transporters that extrude fluorescent indicators from cells.
Dye Retention: Reduces leakage of intracellular fluorescent indicators.
Solubility: Water-soluble formulation avoids the 1 M NaOH needed to dissolve free-acid probenecid.
Applications: Commonly used to improve dye retention in calcium assays and other intracellular fluorescence assays.

Overview

Probenecid is an inhibitor of organic-anion transporters located in cell membranes. These transporters often extrude fluorescent indicators from cells, and therefore contribute to poor dye retention. This phenomenon usually causes high background in the assays that require the good retention of the dye indicators inside cells. The use of probenecid to inhibit the transporter activity, and thus to reduce leakage of the intracellular dye indicators is a common method for reducing fluorescence background of calcium assays. The commonly used free acid form of probenecid requires the use of 1 M NaOH to dissolve it due to its poor water solubility in neutral water. AAT Bioquest offer the convenient Readiuse™ water-soluble and heat-stable probenecid in the format of a powder, solution or tablet. They are convenient to use and are as effective as the free acid form at the same concentration. Each vial is directly dissolved in 100 mL buffer to make 2.5 mM final concentration of probenecid for your assays.
