Such transporters can extrude dyes and indicators and thus contribute to low signal or high background in assays due to poor cellular retention of dyes. The use of probenecid to block the efflux of intracellular dyes was first described by Di Virgilio et al. (1990), and it has been used with a wide range of anionic dyes and conjugates. The commonly used free acid form of probenecid is difficult to dissolve, requiring 1M NaOH to prepare a solution. Our water-soluble probenecid sodium salt dissolves quickly in assay buffer and eliminates the need for handling caustic NaOH. Each vial is directly dissolved in 1 mL buffer to make a 250 mM stock solution. Typical working concentrations in cell-based assays are 1-2.5 mM.\u00a0 <\/p>\n<ul>\u00a0 <\/p>\n<li>Colorless solid soluble in water (77mg\/mL of water)<\/li>\n<p>\u00a0 <\/p>\n<li>C<sub>13<\/sub>H<sub>18<\/sub>NNaO<sub>4<\/sub>S<\/li>\n<p>\u00a0 <\/p>\n<li>MWt: 307.34<\/li>\n<p>\u00a0 <\/p>\n<li>Store desiccated at room temperature<\/li>\n<p>\u00a0 <\/p>\n<li>[23795-03-1]<\/li>\n<p>\u00a0 <\/ul>\n<h3>Handling<\/h3>\n<p>Store with desiccant; Protect from light<\/p>\n<div style=\"margin:18px 0 4px;padding:11px 14px;background:#fdf4f4;border:1px solid #e6bdbd;border-left:3px solid #c41e3a;border-radius:4px;font-size:13px;line-height:1.55;color:#3a3a3a\"><strong style=\"color:#8a1524\">For Research Use Only (RUO).<\/strong> This product is sold strictly for laboratory research use only. <strong>Not for human or veterinary consumption, therapeutic, or diagnostic use.<\/strong> Any pharmacological, therapeutic, cosmetic, or biological effects described above are provided as research context only and do not represent intended or approved uses of this product.<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Probenecid is commonly used to inhibit organic-anion transporters located in the cell membrane.
