| 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. | | References | [1] BHUMI PATEL .
