Description

LyP-1 TFA is a cyclic 9 amino acids tumor homing peptide and selectively bind to p32 receptors overexpressed in various tumor-associated cells[1].

In Vivo

LyP-1 TFA (8 weeks) shows a remarkable reduction in plaque formation and plaque occupation rates in the LyP-1-treated group. In addition, a higher apoptotic rate in macrophages released from hypoxic plaques is observed after the treatment of LyP-1when compared to control peptide[1].
The LyP-1 peptide is labeled with a near-infrared fluorophore (Cy5.5) for optical imaging.
At days 3, 7, 14 and 21 after inoculation with 4T1 cells, tumor-bearing BALB/C mice is injected Cy5.5-LyP-1 (0.8 nmol) through the middle phalanges of the upper extremities of the tumor-bearing mice. The fluorescence intensities were 0.024, 0.038, 0.048 and 0.106×106?photon/cm2/sec respectively at days 3, 7, 14 and 21 after tumor cell inoculation, which are 1.02, 1.63, 2.04, and 4.52-fold higher than in the contralateral LNs. Cy5.5-LyP-1 staining in LNs co-localized with LYVE-1, suggesting lymphatics-specific binding of LyP-1 peptide[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: ≥ 2.5 mg/mL (2.26 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 (2.26 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.
