Fig. 2.

Clot lysis curves detected by two different wavelengths. The absorbance at 405 nm was much higher than the absorbance at 671 nm. Curves 1–4: kinetic absorbance curves at 405 nm generated from 4 independent experiments. Curves 5–8: kinetic absorbance curves at 671 nm generated from 4 independent experiments. The experiments were conducted with a high level of rtPA (curves 1,2,5,6) and a low level of rtPA (curves 3,4,7, and 8) with two replicates for each condition.
