    Immunofluorescence staining displays weaker Bcl-2 fluorescence intensity in lung cancer cells incubated with RBCm-Obatoclax Mesylate (OM)/PLGA, accompanied with stronger expression of pro-apoptotic signal Bax in comparison to the Con group.

    PLGA (50:50) purchased from MedChemExpress. Usage Cited in: Biomed Pharmacother. 2020 Sep;129:110371.  [Abstract]

    Bcl-2 and Bcl-xl protein expression levels are restrained in A549 and H1975 cells treated with RBCm-OM/PLGA; however, Bax, cleaved Caspase-3, Caspase-9 and PARP are up-regulated following RBCm-OM/PLGA incubation. Also, free Obatoclax Mesylate (OM) does not influence the expression change of all these proteins.

    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% Corn Oil

      Solubility: ≥ 2.5 mg/mL; Clear solution

      This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

      Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

    Calculation results:
    Working solution concentration: mg/mL
    Method for preparing stock solution: mg drug dissolved in μL  DMSO (Stock solution concentration: mg/mL).
    The concentration of the stock solution you require exceeds the measured solubility. The following solution is for reference only. If necessary, please contact MedChemExpress (MCE).
    Method for preparing in vivo working solution for animal experiments: Take μL DMSO stock solution, add μL . μL , mix evenly, next add μL Tween 80, mix evenly, then add μL Saline.
     If the continuous dosing period exceeds half a month, please choose this protocol carefully.
    Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.

    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.
