제품 설명

SPACE peptide is a skin penetrating peptide (SPPs). SPACE peptide can enhance topical delivery of a macromolecule, hyaluronic acid[1][2][3].

In Vitro

SPACE peptide, when conjugates to cargoes such as small molecules and proteins, is able to facilitate their penetration across the stratum corneum into epidermis and dermis[2].
SPACE peptide also exhibits increased penetration into various cells including keratinocytes, fibroblasts, and endothelial cells, likely through a macropinocytosis pathway[2].
SPACE peptide enhances Cyclosporine A skin penetration, via a transcellular pathway, enhancing its partitioning into keratin-rich corneocytes through concurrent binding of SPACE with keratin and Cyclosporine A[3].

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 (2.29 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 (2.29 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.

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.

Cell Assay 
[2]

The cytotoxicity of SPACE peptide is assessed using the MTT Cell Proliferation Assay. HEKa cells are seeded in 96-well microplates at a density of 5000 cells/well. Cultures are allowed to grow until they reaches ~80% confluency. Cells are then incubated with 150 μL of 10, 5, 2.5, or 1.25 mg/mL SPACE peptide in media. Media only is used as a negative control, and media without cells is used to subtract background. Cytotoxicity is assessed for 1, 4, and 12 h incubation periods[2].

Animal Administration
[3]

Mice: Female BALB/c mice (knockdown of GAPDH protein) are anesthetized using isoflurane inhalation (2-3%), the back skin of animals is shaved, and a cylinder with an exposed skin area of 1.8 cm2 is attached to the back of mice. 200 μL of the SPACE peptide is topically applied in the attached cylinder, and is manually spread over the entire exposure area. Applied test solutions are allowed to incubate with the exposed skin for 6 hours while keeping animals under minimal anesthesia. After 6 hours, the cylinder is carefully removed, and the entire exposure area is covered with sterile gauze and a breathable bandage. After 72 hrs, animals are sacrificed and skin biopsies (5 mm diameter) are collected from treated area of the animal’s skin. Total protein concentration in the skin biopsy tissue is determined[3].

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.
