NPGB Chemical Properties,Uses,Production

Uses

4-Nitrophenyl 4-guanidinobenzoate hydrochloride has been used:

  • as a substrate for trypsin for active site titration experiments
  • for pre-treating of mosquito eggs in the interplasmid transposition assay
  • as a component of isotonic buffer to moisten filter paper for mosquito embryo collection

General Description

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

Biochem/physiol Actions

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