Description

TP508 is a 23 amino acid synthetic peptide representing residues 508-530 of human prothrombin which is identified as a potential receptor-binding domain based on competition for high-affinity thrombin binding to fibroblasts.

In Vitro

TP508 treatment reverses radiation effects on NO signaling, restores tube formation and accelerates the repair of radiation-induced DSB in irradiated human endothelial cells[1]. TP508 injection increases responsiveness of endothelial cells from aortic explants to VEGF-stimulated angiogenesis in vitro. TP508 stimulation does not significantly affect the VEGF mRNA levels in normoxic or hypoxic cells[2]. TP508 acts as an antagonist for the effects of thrombin. TP508 peptide inhibits these thrombin-induced effects through a RGD and αvβ3-related mechanism[4].

In Vivo

TP508 (500 μg) in sham-irradiated animals significantly increases the amount of endothelial cell sprouting from aortic explants. TP508 significantly increases the sprouting in sham-irradiated and irradiated animals, more than doubling the amount of sprouting in explants from animals at all exposure doses. TP508 (10 mg/kg) given 24 h after 8.5 Gy gamma irradiation significantly increases 30-day survival in mice, from 26.7 to 73.3%[1]. TP508 injection increases endothelial sprouting and potentiates VEGF-stimulated angiogenesis[2]. In type I diabetic swine, TP508 (1 mg/kg, infusion) reduces infarct size after IR[3].

Peptide Solubility and Storage Guidelines:

1.  Calculate the length of the peptide.

2.  Calculate the overall charge of the entire peptide according to the following table:

  Contents Assign value
Acidic amino acid Asp (D), Glu (E), and the C-terminal -COOH. -1
Basic amino acid Arg (R), Lys (K), His (H), and the N-terminal -NH2 +1
Neutral amino acid Gly (G), Ala (A), Leu (L), Ile (I), Val (V), Cys (C), Met (M), Thr (T), Ser (S), Phe (F), Tyr (Y), Trp (W), Pro (P), Asn (N), Gln (Q) 0

3.  Recommended solution:

Overall charge of peptide Details
Negative (<0) 1.  Try to dissolve the peptide in water first.
2.  If water fails, add NH4OH (<50 μL).
3.  If the peptide still does not dissolve, add DMSO (50-100 μL) to solubilize the peptide.
Positive (>0) 1.  Try to dissolve the peptide in water first.
2.  If water fails, try dissolving the peptide in a 10%-30% acetic acid solution.
3.  If the peptide still does not dissolve, try dissolving the peptide in a small amount of DMSO.
Zero (=0) 1.  Try to dissolve the peptide in organic solvent (acetonitrile, methanol, etc.) first.
2.  For very hydrophobic peptides, try dissolving the peptide in a small amount of DMSO, and then dilute the solution with water to the desired concentration.

Animal Administration
[1]

Mice: One hour after irradiation, mice are placed in a restrainer and intravenously (i.v.) injected through the tail vein with a single dose of TP508 in 100 μL sterile saline or 100 μL sterile saline alone. After 24 h, the mice are euthanized by CO2 inhalation and thoracic aortas are isolated from TP508- or saline-alone treated mice and transferred to culture dishes containing cold sterile EBM. The periaortic fibro-adipose tissue is removed under a dissecting microscope and aortas are rinsed with cold EBM and cut transversely to create 1 mm aortic rings (appr 10 per aorta). Aortic rings are cut, opened, and the inner endothelial surface is placed directly on Matrigel matrix-coated 24-well plates. Aortic explants are cultured in a 5% CO2 atmosphere at 37°C in EGM containing 5% FBS and SingleQuots endothelial growth factors. Endothelial cell sprouting is monitored daily by inverted phase contrast microscopy and images are captured using SPOT RT camera and advanced imaging software at 40× and 100× magnification.
