Descripción general

4-Nitrophenyl 4-guanidinobenzoate hydrochloride (pNPGB) is a trypsin substrate.[1] It is more water-soluble than 4-methylumbelliferyl 4-guanidinobenzoate and is preferred in spectrophotometric assay.[2]

Aplicación

4-Nitrophenyl 4-guanidinobenzoate hydrochloride has been used:
  • as a substrate for trypsin for active site titration experiments[3]
  • for pre-treating of mosquito eggs in the interplasmid transposition assay [4]
  • as a component of isotonic buffer to moisten filter paper for mosquito embryo collection[5]

Acciones bioquímicas o fisiológicas

4-Nitrophenyl 4-guanidinobenzoate hydrochloride (pNPGB) inhibits phenoloxidase enzyme and delays embryo chorionic membrane hardening.[5]
