Product Description
ABMA is a broad spectrum (a wide range) inhibitor of intracellular toxins and pathogens. ABMA effectively protects cells from a variety of toxins and pathogens like viruses, intracellular bacteria, and parasites. ABMA selectively targets host cell late endosomes rather than toxins or pathogens themselves, giving it broad spectrum (a wide range) anti-infectious activity.
Biological Activity I Assay Protocols (From Reference)
ln Vitro
Cells protected by ABMA are resistant to four types of bacterial toxins: Bacillus anthracis (LT), Corynebacterium diphtheriae (DT; EC50 of 62.9 μM), Clostridium difficile toxin B (TcdB; EC50 of 73.3 μM), Clostridium sordellii lethal toxin (TcsL; EC50 is 86.7 μM), three viruses: Ebola virus (EC50 of 3.3 μM), rabies (EC50 of 19.4 μM), dengue 4 virus (EC50 of 8.2 μM), two intracellular chlamydia bacteria (Simkania negevensis and Chlamydia trachomatis), and Leishmania infantum at micromolar levels (EC50 of 7.1 μM) [1]. The cytotoxicity of ricin was reduced in A549 cells by ABMA treatment, with an EC50 of 3.8 μM and a protection factor (R) ranging from 5 to 10 at 30 μM. Against the induction of ricin, ABMA maintains nearly all of its biological action. up to six days cytotoxic [1].
ln Vivo
Following intraperitoneal injection of LD90 Foxx narcotoxin, the neck is protected by ABMA therapy (200–400 mg/kg; female BALB/c mice) [1].
Animal Protocol
Animal/Disease Models: Pathogen-free female balb/c (Bagg ALBino) mouse (6 weeks old) administered ricin [1]
Doses: 2 mg/kg, 20 mg/kg, 200 mg/kg
Route of Administration: intraperitoneal (ip) injection
Experimental Results: Based on survival Curve, statistically significant protection was observed with a single intraperitonealdose of 2 mg/kg. A dose of 20 mg/kg adequately protected animals until day 21. The 200 mg/kg dose provided 80% protection against ricin challenge in mice, with one animal dying on day 15.

Solubility Data
Solubility (In Vitro)
DMSO : ~125 mg/mL (~356.85 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 6.25 mg/mL (17.84 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 62.5 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: ≥ 6.25 mg/mL (17.84 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 62.5 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.

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
