    Description

    Dihydrorhodamine 123 (DHR 123) is a fluorescent probe (λex=488 nm, λem=525 nm)[1].

    In Vitro

    In the presence of 10 μM Dihydrorhodamine 123 (DHR 123) the stimulation of the neutrophil NADPH oxidase by the addition of 50 nM phorbol 12-myristate 13-acetat (PMA) resultes in an increase in the rate of rhodamine generation. The fluorescent intensity of the cells, in the presence of 10 μM Dihydrorhodamine 123, increases with time following the addition of 50 nM PMA. In the presence of 10 μM Dihydrorhodamine 123, induced HL60 cells show a sustained increase in fluorescence following the addition of 50 nM PMA[1].

    In Vivo:

    Select the appropriate dissolution method based on your experimental animal and administration route.

    For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
    To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
    The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

    • Protocol 1

      Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

      Solubility: 2.5 mg/mL (7.22 mM); Suspended solution; Need ultrasonic

      This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

      Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

    Cell Assay
    [1]

    The HL60 cells are incubated at 6×106 cells/mL in Krebs-Ringer buffer at 37°C containing 10 μM Dihydrorhodamine 123 (DHR). The generation of O2- is initiated by the addition of 50 nM phorbol 12-myristate 13-acetat (PMA) and the progress of the generation of rhodamine 123 is monitored in 50-μL aliquots (3×105 cells) diluted tenfold before analysis. The uninduced HL60 cells are loaded with 5 μM carboxy SNARF-1 AM acetate (SNARF-AM) in the Na+ medium for 10 min at 37°C and washed by centrifugation and resuspension to remove unhydrolysed SNARF ester[1].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
