Product Description

Biological Activity

Description Sodium Monofluorophosphate is a competitive inhibitor of pyruvate kinase and alkaline phosphatase with Ki of 3.4 mM and 69 μM, respectively, which also irreversibly inhibits phosphorylase phosphatase with Ki of 0.5 mM.
In vitro Monofluorophosphate (1 mM) induces a three-fold increase in proliferation rate of embryonic chick calvarial cells in serum-free monolayer cultures. 30 μM of Monofluorophosphate increases the activity of DNA and alkaline phosphatase in calvarial cells by 135% and 178%, respectively. In cultured intact calvaria, 30 μM of Monofluorophosphate increases DNA activity, alkaline phosphatase activity and collagen production by 143%, 186% and 151%, respectively. [2]
In vivo Monofluorophosphate displays potent activity on bone immobilization in vivo. Rats supplied with drinking water containing 50 ppm F as Monofluorophosphate show a significant increase in the bone sickness of mobile tibia and immobile tibia, compared with fluoride-free water group (1.48 vs 0.98 mm, 0.79 vs 0.40 mm, respectively). Monofluorophosphate does not change the specific gravities of the immobilized and non-immobilized tibiae of the rats. Administration of Monofluorophosphate increases the mineralization rate of bones and counteracts the decrease in bone thickness, ash content and specific gravity induced by immobilization, without changing the Ca/P ratio of the ash.

Protocol(Only for Reference)

Kinase Assay: [2]

Alkaline phosphatase activity assay ALP activity is measured colorimetrically using PNPP as a substrate in carbonate/tris buffers containing 1 mM MgCl2, in 96-place tissue culture microwell plates (total reaction volume = 0.3 mL). Reactions are initiated by addition of the enzyme, and incubated at ambient room temperature (22 ℃). Production of p-nitrophenolate is monitored by measuring the time-dependent change in absorbance at 410 nm, using a Dynatech automatic microwell plate reader.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
