How can you use “vanadate” in a sentence? Here are some example sentences to help you improve your vocabulary:
Cells were resuspended in lysis buffer (10 mM Tris (pH 7.5), 1 mM EDTA, 50 mM NaCl, 0.25% Nonidet P-40, 1 mM PMSF, 1 mg of aprotinin/mL, 0.1 mM sodium vanadate, 10 mM sodium molybdate, and 10 mM β-glycerol phosphate) and lysed by sonication with a microtip on setting 2 and 20% duty cycle for 10 s.
They were then lysed in a protein kinase lysis buffer [50 mM HEPES, pH 7.5, 150 mM NaCI, 1.5 mM MgCI2, 1 mM EGTA, 1 mM sodium vanadate, 50 mM sodium fluoride, 20 mM beta-glycerophosphate, 10% (vol/vol) glycerol, 1% (vol/vol) Triton X-100, and protease inhibitors (1 mM PMSF, 1 ug/ml pepstatin A1, 1 ug/ml leupeptin, and 1 ug/ml aprotinin].
The interaction between Slimb and E2F depends on a phosphorylation event as it is prevented by the presence of active alkaline phosphatase (lane 4) but not when the phosphatase is inhibited by sodium vanadate (lane 5).
NTPDases do not form phosphorylated intermediates during catalysis, a conclusion also supported by lack of vanadate sensitivity and Pi product inhibition [ 3 4 5 6 ] . The catalytic reaction appears to be irreversible and no partial reactions have been observed [ 7 8 ] . Divalent cations like Ca 2+or Mg 2+are required for activity, and maximal activity is reached when the concentrations of substrates and divalent cations are equal [ 1 ] . The specific activities of NTPDases vary over a broad range from ten thousand units for potato apyrase to less than one hundred units for chicken gizzard ecto-ATPase [ 9 10 ] . Sequence comparisons indicate that most of NTPDases contain five highly conserved regions, apyrase conserved region, ACR1 - ACR5 [ 9 11 ] . However, the catalytic sites have not been identified, although ACR1 and ACR4 have been implicated in β- and γ-phosphate binding, respectively [ 9 ] .
COS-7 cells were harvested in PBS containing 0.1 mM sodium vanadate and collected by low speed centrifugation.
