He mea hou a palekana hoʻi ʻo Tetramethylbenzidine i ka chromogenic reagent; Ua pani mālie ʻo TMB i ka carcinogen benzidine ikaika a me nā mea hoʻohui benzidine carcinogenic ʻē aʻe, a ua hoʻohana ʻia i ka hoʻāʻo ʻana i ka hale hana lapaʻau, ka hoʻokolokolo forensic, ka noiʻi kalaima, a me ka nānā ʻana i ke kaiapuni; ʻOi loa i ka hoʻāʻo ʻana i ka biochemical lapaʻau, ʻo TMB, ma ke ʻano he substrate hou no ka peroxidase, ua hoʻohana nui ʻia i ka enzyme immunoassay (EIA) a me ka enzyme-linked immunosorbent assay (ELISA).
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
