WebHRP is the enzyme of choice for most researchers performing ELISAs and can be used with a variety of substrates (see below), most of which are more sensitive than AP equivalents. F. Substrates . Enzymatic signal generation requires the catalysis of a substrate to produce a colored or fluorescent compound or chemiluminescence (visible light). WebHRP systems have an advantage over other detection systems in that both the enzyme conjugate and colorimetric detection substrates are economical. The most common substrates for colorimetric HRP are 4-Chloro-1-naphthol (4CN) (Hawkes et al. 1982) and 3, 3'-diaminobenzidine (DAB) (Tsang et al. 1985) (see figure below).
