Anticoagulation assay
Determination of aPTT and PT were performed according to
the manufacture’s specifications using Thrombotimer (Behnk
Elektronik, Germany). In brief, citrated normal human plasma
(90 μl) was mixed with 10 μl of curcumin or BDMC and incubated
for 1 min at 37°C. Then, aPTT assay reagent (100 μl)
was added to the mixture and incubated for 1 min at 37°C.
Thereafter, 20 mM CaCl2 (100 μl) was added and the clotting
time was recorded. For the PT assay, citrated normal human
plasma (90 μl) was mixed with 10 μl of a curcumin or BDMC
stock and incubated for 1 min at 37o
C. Then, PT assay reagent
(200 μl), preincubated for 10 min at 37o
C, was added and the
clotting time was recorded.
