General description

Griess reagent is based on Griess reaction. The components include naphthylethylenediamine dihydrochloride suspended in water and sulphanilamide in phosphoric acid. This reagent reacts with nitrite in samples to form a purple azo product, absorbance of which is measured at 546 nm.

Application

Griess reagent (modified) has been used:
  • in the nitrite assay of primary spinal cord glial cells stimulated with supernatant of damaged sensory neuron (SDSN)
  • for measuring nitrite/nitrate oxidized from nitric oxide in stimulated chondrocytes
  • for measuring nitric oxide (NO) degradation in RAW264.7 macrophage cells
  • to measure the concentration of nitric oxide(NO) in the conditioned media from cultured macrophages (MΦs)
  • to determine the relative levels of NO released by BEAS-2B bronchial cells in the culture supernatants

Tissue factor pathway inhibitor (TFPI) inhibits tissue factor-induced coagulation, but may, via its C terminus, also modulate cell surface, heparin, and lipopolysaccharide interactions as well as participate in growth inhibition. Here we show that C-terminal TFPI peptide sequences are antimicrobial

Minocycline, a semisynthetic tetracycline derivative, protects brain against global and focal ischemia in rodents. We examined whether minocycline reduces excitotoxicity in primary neuronal cultures. Minocycline (0.02 microm) significantly increased neuronal survival in mixed spinal cord (SC) cultures treated with 500
