Benzamidine is a competitive protease inhibitor that blocks the hydrolytic cleavage of glucagon by plasmin, trypsin and thrombin. Benzamidine effectively inhibits the degradation of glucagon by relevant proteases during the collection, storage and analysis of human plasma and blood samples. During in vivo metabolism, Benzamidine undergoes N-hydroxylation and produces multiple metabolites, exhibiting characteristics of delayed excretion or biphasic elimination. Benzamidine only induces slight single-strand DNA breaks at high concentrations and shows no significant genotoxic potential overall. Benzamidine may interfere with the detection of some glucagon antisera, but does not affect key antigen-antibody affinity at specific concentrations. Benzamidine can be used as a stabilizer in glucagon radioimmunoassays to ensure the accuracy and recovery rate of detection results.

製品説明

Benzamidine is a competitive protease inhibitor that blocks the hydrolytic cleavage of glucagon by plasmin, trypsin and thrombin. Benzamidine effectively inhibits the degradation of glucagon by relevant proteases during the collection, storage and analysis of human plasma and blood samples. During in vivo metabolism, Benzamidine undergoes N-hydroxylation and produces multiple metabolites, exhibiting characteristics of delayed excretion or biphasic elimination. Benzamidine only induces slight single-strand DNA breaks at high concentrations and shows no significant genotoxic potential overall. Benzamidine may interfere with the detection of some glucagon antisera, but does not affect key antigen-antibody affinity at specific concentrations. Benzamidine can be used as a stabilizer in glucagon radioimmunoassays to ensure the accuracy and recovery rate of detection results[1][2][3].
体外実験

Benzamidine (0.05-0.1 M; 6-24 h at 4°C) inhibits the degradation of [125I]-glucagon in undiluted human plasma; the recovery rate of glucagon in undiluted human plasma treated with 0.05 M benzamidine exceeds 85%[1].
Benzamidine (1-20 μmoles/tube or 5-20 μmoles/tube; 1 h) exhibits only weak, marginal genotoxicity (inducing DNA single-strand breaks) in primary rat hepatocytes, and shows no genotoxicity in CO631 cells at the tested concentrations[2].
Benzamidine (1-10 μmoles/plate; 72 h) does not induce selective amplification of SV40 DNA in CO631 cells[2].

Dosage: 10 mg/kg
Administration: i.v.; single dose

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
