Product Description

Bromodeoxyuridine (BrdU; Broxuridine; 5-Bromo-2'-deoxyuridine; BUdR) is a nucleoside analog with potential anticancer activity. It has been used in the detection of proliferating cells and functions as an antimetabolite anticancer agent by competing with thymidine for incorporation into DNA. Early on in the dedifferentiation process, the impact of 5-BrdU on the proliferation of grown Nicotiana glauca pith explants was investigated. Only when administered within the first 72 hours of culture did it turn out to be completely inhibitory; this inhibition could be overcome by simultaneously adding either thymidine or deoxyeytidine.

Biological Activity I Assay Protocols (From Reference)
ln Vitro

Bromodeoxyuridine causes a dose-responsive, progressive suppression of cancer cell line and cancer stem cell population expansion in RG2 rat glioma cells. The cell cycle profile of BJ fibroblasts and H9 cells is changed by bromodeoxyuridine.[1]
BrdU is stably integrated into the DNA, making it suitable for use in evaluating other cell processes such as proliferation.[2]

ln Vivo
Bromodeoxyuridine (300 mg/kg, i.p. or 0.8 mg/ml, p.o.) markedly slows the progression of the tumor in the rat glioma RG2 tumor model.[1]
Cell Assay
Initially plated at 2000 cells/cm2, cultures are measured using a Z2 Coulter Counter. After treating RG2 rat glioma cells once for 24 hours with 0, 1, 10, or 50 µM BrdU, cumulative growth curves were measured over a period of 18 days. After five, twelve, and eighteen days of treatment, control and treated cells are counted and replated at equal densities.

Solubility Data
Solubility (In Vitro)
DMSO: 61~250 mg/mL (198.6~814.1 mM)
Water: <1 mg/mL
Ethanol: ~3 mg/mL (~9.8 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (6.77 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 20.8 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: ≥ 2.08 mg/mL (6.77 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 20.8 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.

Solubility in Formulation 3: ≥ 2.08 mg/mL (6.77 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.


Solubility in Formulation 4: 14.29 mg/mL (46.53 mM) in PBS (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication.

*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
