In Vitro

After culturing in MRS broth with 0.2 to 1.0% soy Lecithin, the survival rate of harvested cells increases significantly (P<0.05) in the 0.3% bile challenge compare with the no added soy Lecithin group. The cells incubated with 0.6% soy Lecithin are able to grow in an MRS broth with a higher bile salt content. The cell surface hydrophobicity is enhanced and the membrane integrity in the bile challenge increases after culturing with soy Lecithin. A shift in the fatty acid composition is also observed, illustrating the cell membrane changes in the soy Lecithin culture[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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 0.5 mg/mL; 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 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: ≥ 0.5 mg/mL; 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.

Cell Assay
[1]

MRS broths are supplemented with soy Lecithin concentrations of 0, 0.2, 0.4, 0.6, 0.8 and 1.0%. Each broth is inoculated with a tested strain culture (2%, v/v) and anaerobically incubated at 37°C for 20 h. After incubation, the bacterium cells are harvested by centrifugation at 8000 g for 10 min at 4°C and washed twice in PBS (pH 6.5) plus ethanol (5%, v/v). Strain bile resistance is assessed. The numbers of viable cells are counted by the pouring plate method, and each batch is tested three times[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.
