In Vitro

Prostacyclin (PGI2) is synthesised in oviductal fluid and enhance the embryo development[1].
Iloprost is an PGI2 analog, and affects maturation and developmental competence of bovine oocytes[1].
Iloprost (0.5 μM; 22-24 h) increases blastocyst rates of bovine embryos as well as proportion of expanded blastocysts[1].
Iloprost (0.5 μM; 22-24 h) assists maturation rates and cumulus cell expansion of bovine oocytes, and increases the mRNA expression of genes related to cumulus expansion[1].
Iloprost (0.5 μM; 22-24 h) reduces the occurrence of apoptosis in COCs and promotes an anti-apoptotic balance in the transcription of genes involved in apoptosis (BAX and BCL2) [1].

RT-PCR[1]

Cell Line: Bovine oocytes: cumulus oocyte complexes (COCs)
Concentration: 0.5 μM
Incubation Time: 22-24 hours
Result: Increased mRNA expression levels of cysteine proteinases cathepsins, including ADAM17, AREG, and TNFAIP6 23 and cathepsin genes (CTSK and CTSS).
In Vivo

Iloprost (0.3 mg/kg/min; via s.c. mini pumps; 33 d) has a significant anti-metastatic activity in a spontaneously metastasizing tumor model in rat[2].
Iloprost (0.2 mg/kg/d; i.p.; 10 d) attenuates hyperoxia effects and reduces inflammation in the newborn mouse lung, with Cyclooxygenase-2 (COX-2/PTGS2) mediates hyperoxia-induced impairment[3].
Iloprost (0.2 mg/kg; i.v. or i.p.) exhibits short half-life, and is often administered by means of frequent (every 2-4h) inhalation in treatment[4].

Animal Model: Spontaneously metastasizing R 3327 MAT Lu prostate carcinoma in Cop rat[2]
Dosage: 0.3 mg/kg/min
Administration: Subcutaneous administration via Alzet mini pumps; continuously for 33 days
Result: Reduced the number of visible lung metastases, but had no effect on the growth of the primary tumor.
This action was based on the ability to reduce the attachment of tumor cells to platelets and to inhibit adhesion of tumor cells-platelet aggregates to the endothelial lining.
Animal Model: Newborn C57BL/6 mice (4-day-old)[3]
Dosage: 0.2 mg/kg
Administration: Intraperitoneal injection; once daily; 10 days
Result: Reduced markedly pro-inflammatory cytokines IL-1β and TNF-α mRNA and protein.
Inhibited alveolar septation, reduced hyperoxia-induced total lung resistance and myeloperoxidase, prevented hyperoxia-reduced lung microvascular density.

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 (6.94 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 (6.94 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.

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.
