Bradykinin is a short-lived vasoactive peptide with a reported in vivo half-life of 17 seconds and is rapidly converted to bradykinin in the circulation (1-5). Bradykinin (1-5) is the result of two sequential cleavages of bradykinin by ACE at the Pro7-Phe8 and Phe5-Ser6 links. It has been discovered as the primary stable metabolite of bradykinin in human beings. The last half-life is minutes. Both bradykinin and bradykinin(1-5) reduced α- and γ-thrombin-induced platelet aggregation (P<0.01 compared with baseline). Bradykinin(1-5) reduces gamma-thrombin-induced platelet aggregation by 50% at an estimated dose of 183±3 pmol/min. Neither bradykinin nor bradykinin(1-5) affects thrombin receptor activating peptide-induced platelet aggregation, consistent with bradykinin and bradykinin(1-5) functioning by blocking thrombin receptor cleavage and thrombin receptor release to suppress thrombin-induced platelet aggregation. Activating peptides. Bradykinin (1-5) significantly attenuates α-thrombin-induced platelet aggregation but not TRAP 1-6-induced platelet aggregation. Bradykinin (1-5) substantially suppresses platelet aggregation induced by γ-thrombin (500 nM) with an ED50 of 183±2 pmol/min[1].

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.37 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (4.37 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 2.5 mg/mL (4.37 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
