Maxadilan TFA
Based on 1 Customer Validation
Maxadilan TFA is a specific irreversible PAC1 receptor agonist and a potent vasodilator peptide present in the salivary glands of sand flies. Maxadilan TFA exhibits anti-apoptotic activity in hADSCs. Maxadilan TFA inhibits pro-inflammatory cytokines (TNF-α) and enhances anti-inflammatory mediators (IL-10). Maxadilan TFA can activate leukocytes and inhibit vascular permeability through PAC1 receptors. Maxadilan TFA promotes neural differentiation of human adipose-derived stem cells. Maxadilan TFA can be used to study endotoxin shock, atherosclerosis, and neurodegenerative diseases[1][2][3][4][5].

Maxadilan (20-200 nM, 24 h) TFA enhances the proliferation and migration of human adipose-derived stem cells (hADSCs), and enhances cytokine-induced neural redifferentiation of hADSCs into functional neurons[2].
Maxadilan (80 nM, 24-48 h) TFA decreases the ratio of apoptosis with serum withdrawal treatment in hADSCs through PAC1R ligand-dependent activity mediated by the PKA signaling pathway and PAC1R dimer-dependent activity mediated by the Wnt/β-catenin signaling pathway[2].
Maxadilan (80 nM, 1-3 days) TFA induces an efficient differentiation of hADSCs into neural-like cell morphology in chemical neural induction medium[2].
Maxadilan (5-100 ng/mL) TFA induces human neutrophil chemotaxis[3].
Maxadilan (134 nM, 30 min) TFA increases arteriolar dilation, associated with plasma leakage and leukocyte accumulation in one hamster cheek pouch[3].

Solvent & Solubility
DMSO : 100 mg/mL (Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL; 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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL; 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.
