| Description | Proadrenomedullin N-terminal 12 peptide (PAMP-12), an endogenous fragment originating from the adrenal medulla and spanning amino acids 9-20 of human PAMP-20, plays a role in causing hypotension. It functions as an agonist for the MAS-related G protein-coupled receptor family member X2 (MRGPRX2), inhibiting forskolin-stimulated cAMP accumulation in CHO cells expressing human MRGPRX2 (EC50 = 57.2 nM) and selectively prompting calcium mobilization in these cells (EC50 = 41 nM), but not in cells expressing MRGPRX1, MRGPRX3, or MRGPRX4 at 1 µM. As an antagonist of nicotinic acetylcholine receptors (nAChRs), PAMP-12 obstructs carbachol-triggered catecholamine release and the influx of calcium and sodium (IC50s = 1.3, 0.39, and 0.87 µM, respectively) in primary bovine adrenal chromaffin cells, with no effect on histamine-induced responses (IC50s = >1 µM for all). Additionally, it decreases mean arterial blood pressure in normotensive rats at doses ranging from 10 to 50 nmol/kg. |

For example, if the dosage of your experiment is 10mg/kg, the weight of each animal is 50g, and the volume of the dosing is 100μL, then the working solution concentration of your experiment is 5mg/mL. If the formula you used is 5% DMSO+ 30% PEG300+ 5% Tween 80 + 60% Saline/PBS/ddH2O, the preparation method is as follows:
Mother liquor preparation method: 5mg of drug dissolved in 100μL DMSO (mother liquor concentration is 50mg/mL). Preparation method of in vivo formulation: For 1mL of working solution preparation, take 50μL of DMSO mother liquor, add 300 μL of PEG300 to mix well and clarify, then add 50μL of Tween-80 to mix well and clarify, and finally add 600μL of Saline/PBS/ddH2O to mix well and clarify.Note:
- For Reference Only. Please choose the appropriate dissolution protocol according to your experimental animal and administration method.
- We suggest that in cell experiments, the final concentration of DMSO is not more than 0.1%, in animal experiments, for healthy mice, the final concentration of DMSO is not more than 10%; For nude or frail mice, the final concentration of DMSO is not more than 2%.
