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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (7.02 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

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

    Solubility: ≥ 2.5 mg/mL (7.02 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    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
[2]

Individual CCD segments are dissected from rabbit and mouse kidney.The measurements of [Na+]i are used as a reflection of Na+ transport across the apical membrane. EnaC-specific activity is assessed by applying 10−6 M of the ENaC blocker Benzamil hydrochloride, a concentration that does not affect Na+:H+ exchange. Experiments are performed in the presence/absence of luminal Benzamil hydrochloride or the Na:H exchanger blocker HOE694 administers with/without the AT1 receptor blocker candesartan. Final DMSO concentrations are below 0.1% [2].

Animal Administration
[1]

For the acute intracerebroventricular injection in anesthetized rats. A guide cannula is inserted into the right lateral cerebral ventricle, and Benzamil hydrochloride (0.1 nmol/kg, n=6; 1 nmol/kg, n=6; 10 nmol/kg,n=7) or vehicle (n=6) is injected into the right lateral ventricle through a cannula connected to a microsyringe 15 min before the start of intracerebroventricular infusion of hypertonic NaCl. Each injection consists of a volume of 10 μL deliver manually over a period of 30 s. To investigate the effects of Benzamil hydrochloride on the pressor response induced by intracerebroventricular injection of the pressor agent other than hypertonic NaCl, endothelin-1, which has a potent pressor action in the brain of rats, is intracerebroventricularly injected (1 nmol/10 μL) 15 min after the intracerebroventricular preinjection of Benzamil hydrochloride (10 nmol/kg, n=6) or the vehicle (n=6), and mean arterial pressure, heart rate, and abdominal sympathetic nerve firings are recorded for 20 min. Catheters are implanted into both the femoral artery and vein of 12-wk-old male rats anesthetized with urethan. Both catheters are filled with heparinized saline (50 U/mL). Fifteen minutes before the start of intracerebroventricular infusion of hypertonic NaCl, Benzamil hydrochloride (10 nmol/kg, n=6) or vehicle (10 μL, n=6) is injected into a tube connects to the femoral venous catheter by directly inserting the microsyringe, and 0.1 ml of isotonic saline solution is injected through the catheter to deliver the contents into the venous circulation[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.
