BMAP-27 acetate
Based on 1 Customer Validation
BMAP-27 acetate is a cationic amphipathic α-helical antimicrobial peptide with anticancer activity. BMAP-27 acetate disrupts the integrity and permeability of cell membranes, leading to the leakage of intracellular DNA, proteins and alkaline phosphatase. BMAP-27 acetate increases intracellular ROS levels and reduces plasma endotoxin and TNF-α concentrations. BMAP-27 acetate can be used in studies related to Salmonella infection, breast cancer, lung cancer and obstructive jaundice.

Biological Activity
BMAP-27 (2-4 μM) TFA potently inhibits the growth of S. aureus and E. coli with MIC values of 2-4 μM[2].
BMAP-27 (2-5 μM; 20-60 min) TFA rapidly kills S. aureus and E. coli, achieving near-complete bacterial death within 20 min at its MIC of 2 μM[2].
BMAP-27 TFA efficiently depolarises the cytoplasmic membranes of S. aureus and E. coli at concentrations lower than its MIC of 2-4 μM[2].
BMAP-27 (2 days) TFA exhibits strong dose-dependent cytotoxicity against human MDA-361 and A549 cancer cells, with IC50 values lower than its haemolytic activity IC50[2].
BMAP-27 (1 h) TFA exhibits moderate dose-dependent haemolytic activity against human red blood cells[2].
BMAP-27 (5-32 μM; 2-5 min) TFA potently disrupts anionic POPC/POPG (2:1) membranes, shows moderate disruption of zwitterionic POPC/cholesterol (4:1) membranes at high concentrations, and exhibits Phosphatidylserine (PS) (HY-A0183)-dependent membrane disruption that correlates with its anticancer activity[2].

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.
