Reaction principle: The thrombin chromogenic substrate S-2238 is a specific substrate for thrombin. S-2238 can be hydrolyzed by thrombin to release the starting color group p-nitroaniline (pNA), which can be detected at a wavelength of 405 nm.
Purpose: Used to detect the concentration of thrombin in blood samples. S-2238 can only be used for laboratory scientific research, in vitro diagnosis, and quality control in the pharmaceutical industry, and cannot be used as a drug or in vivo diagnosis.
