TP508 TFA
Based on 1 Customer Validation
TP508 TFA is a 23-amino acid nonproteolytic thrombin peptide that represents a portion of the receptor-binding domain of thrombin molecule. TP508 TFA activates endothelial NO synthase (eNOS) and stimulates production of NO in human endothelial cells. TP508 TFA activates endothelial cells and stem cells to revascularize and regenerate tissues.

eNOS |
TP508 (50 μg/mL; 24 hours; HCAEC) treatment reverses radiation-induced endothelial dysfunction (ED) and loss of NO signaling by attenuating the downregulation of eNOS expression. TP508 treatment is able to stimulate NO production in the irradiated cells[1].
TP508 mitigates effects of nuclear radiation on human endothelial cells in culture restoring endothelial NO production, tube formation and accelerating repair of radiation-induced DNA double-strand breaks (DSB)[1].
TP508 acts as an antagonist for the effects of thrombin. TP508 peptide inhibits these thrombin-induced effects through a RGD and αvβ3-related mechanism[3].
