|Description||Fludarabine Phosphate (F-ara-A, NSC 312887) is an analogue of adenosine and deoxyadenosine, which is able to compete with dATP for incorporation into DNA and inhibit DNA synthesis.|
Fludarabine Phosphate is converted to F-ara-ATP in cells and then incorporated into DNA in a self-limiting manner. Fludarabine Phosphate competes with dATP for incorporation into the A site of the extending DNA strand, which results in termination of DNA strand elongation. Human DNA polymerase α incorporates more Fludarabine Phosphate into DNA than polymerase δ. Fludarabine Phosphate completively inhibits DNA polymerase α and DNA polymerase δ with Ki of 1.1 μM and 1.3 μM, respectively. DNA polymerase δ is also able to excise the incorporated Fludarabine Phosphate from DNA in vitro. 
|In vivo||Fludarabine Phosphate is toxic for tumor-free mice. The maximum tolerated dose (LD10) Fludarabine Phosphate administered as a single dose is 234 mg/kg. The 50% lethal dose is 375 mg/kg. Fludarabine Phosphate administered as a single dose induces fewer number of cells surviving therapy in mice bearing P388 leukemia, accompanied by greater percentage of increase in life span (110%) and increased median survival time. |
|In vitro||DMSO||73 mg/mL (199.88 mM)|
|Water||2 mg/mL warmed (5.47 mM)|
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and SDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and SDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
