Product Information
| Description: | DTNB (Ellman's Reagent) is a chemical used for quantifying the amount or concentration of sulfhydryl groups. It is often used to detect free sulfhydryl groups. DTNB is also an allosteric inhibitor of dengue virus protease (NS2B-NS3Pro) and Streptomyces protease. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
