Technical Support

Ciprofloxacin (Bay-09867) monohydrochloride is an orally active, blood-brain barrier permeable fluoroquinolone antibacterial agent. Ciprofloxacin monohydrochloride exerts bactericidal effects primarily by inhibiting topoisomerase II and IV. Ciprofloxacin monohydrochloride inhibits the proliferation of human dental pulp stem cells and chondrocytes from young rats, and also activates the Akt signaling pathway and upregulates markers such as β-catenin and Nanog to maintain the morphological characteristics of stem cells. Ciprofloxacin monohydrochloride induces significant neurotoxicity and tissue damage, including reducing serotonin and glutathione levels in the brain, inducing oxidative stress and depression-like behaviors, and causing articular cartilage damage. Ciprofloxacin monohydrochloride can be applied to research related to infections of necrotic young permanent teeth and neurotoxicity.

In Vitro

Ciprofloxacin (2.5-10 μg/mL; 24-72 h) preserves the stem cell-like spindle morphology of immortalized human dermal papilla cells, and concentrations of 5 and 10 μg/mL for 72 h significantly increase cell aggregation size and number^[1].
Ciprofloxacin (10 μg/mL; 72 h) preserves CD133 stem cell marker expression and prevents increased procollagen type I fibroblast marker expression in immortalized human dermal papilla cells^[1].
Ciprofloxacin (10 μg/mL; 24-72 h) prevents time-dependent loss of CD133, integrin β1, and ALDH1A1 stem cell markers and increases in procollagen type I fibroblast marker in immortalized human dermal papilla cells; concentrations of 2.5-10 μg/mL for 72 h modulate these markers in a dose-dependent manner^[1].
Ciprofloxacin (2.5-10 μg/mL; 72 h) activates the Akt/GSK3β/β-catenin pathway in immortalized human dermal papilla cells in vitro in a dose-dependent manner, increasing activated Akt, inactivated GSK3β, and β-catenin levels^[1].
Ciprofloxacin (2.5-10 μg/mL; 72 h) activates the Akt/GSK3β/β-catenin pathway and upregulates EMT transcription factors (ZEB1, Snail) in primary human dermal papilla cells in vitro in a dose-dependent manner^[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: ≥ 0.5 mg/mL (1.36 mM); Clear solution

This protocol yields a clear solution of ≥ 0.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (5.0 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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 0.5 mg/mL (1.36 mM); Clear solution

This protocol yields a clear solution of ≥ 0.5 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 (5.0 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
