Quinacrine mustard di-HCl is a fluorescent dye. Quinacrine mustard di-HCl is a polycyclic aromatic agent that works as a mutagen to induce mutants in bacteria. Quinacrine mustard di-HCl induces cell cycle arrest in the G2/M phase. Quinacrine mustard di-HCl may be used for studying plant, animal or human chromosomes.

Biological Activity

ln Vitro	Plant, animal, or human chromosomal DNA strains can be treated with quinacrine mustard dihydrochloride (5 μg/ml)[1]. Quinacrine dihydrochloride (28 μM) increases the amount of mutations that arise following bacterial exposure[2]. 0.2 μM quinacrine mustard dihydrochloride, applied for 4 hours, causes cell cycle arrest in HL-60 cells at the G2+M-phase[3]. In HL-60 cells, quinacrine mustard dihydrochloride (0.2 μM; 4h) had no cytotoxic effect when caffeine (5 mM) is added[3].
Cell Assay	Cell Cycle Analysis[3] Cell Types: HL-60 cells Tested Concentrations: 0.2 µM Incubation Duration: 4 h Experimental Results: Induced cell cycle arrest at G2+M-phase with the accumulation of cells in this compartment by 50%.

Solubility Data

Solubility (In Vitro)

May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples

Solubility (In Vivo)

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *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.

Oral Formulation 3: Dissolved in PEG400 Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose Oral Formulation 6: Mixing with food powders Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.  (Please use freshly prepared in vivo formulations for optimal results.)

Preparing Stock Solutions		1 mg	5 mg	10 mg
	1 mM	1.9790 mL	9.8949 mL	19.7898 mL
	5 mM	0.3958 mL	1.9790 mL	3.9580 mL
	10 mM	0.1979 mL	0.9895 mL	1.9790 mL

*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.
