A convenient method for determination of sodium azide in beverages using ion chromatography is described. This method combines the specificity for azide with a simple sample preparation using a bubble and trap apparatus that removes any interferences. Sodium azide in a sample was acidified, and the azide was converted to the volatile hydrazoic acid, which was trapped in 2.5 mM sodium hydroxide ...

Sodium azide-crystal violet-agar and a modified blood-azide (MBA)-agar were used to isolate Erysipelothrix rhusiopathiae from swine tissues. There was no significant difference in the number of isolations. However, 78% of the isolants from modified blood-azide medium required only 24 hr of incubation, whereas all of the isolants obtained on sodium azide-crystal violet medium required 48 hr.

A mutation has been isolated in the Bacillus subtilis secA gene (secA10) which allows cell growth and residual protein translocation in the presence of 1.5 mM sodium azide. Besides conferring resistance to sodium azide, the corresponding SecA10 mutant protein, in which glutamic acid at position 338 has been changed to glycine, seems to possess a secretion defect even in the absence of azide. In...

The effect of including sodium azide as a bacteriostatic agent in solutions used to dilute antibodies conjugated with the enzyme horseradish peroxidase was examined. An enzyme-linked immunosorbent assay (ELISA) and an immunohistochemical method were used and both techniques demonstrated an inhibitory effect of sodium azide on the activity of the peroxidase conjugates. It is concluded that the u...

Ultra-trace analysis of azide in complicated Irbesartan sample matrix is achieved by the in-line sample preparation technique. Sodium azide is the precursor of Irbesartan, which is used as an anti-hypertensive drug. Due to the toxic nature of sodium azide, reliable determination of azide in Irbesartan is necessary. Irbesartan when analyzed for sodium azide, as per the USP 31-NF26 method, gets a...

The aim of the current study was to investigate the effect of mitochondrial division inhibitor 1 (Mdivi‑1) in sodium azide‑induced cell death in H9c2 cardiac muscle cells. Mdivi‑1 is a key inhibitor of the mitochondrial division protein dynamin‑related protein 1 (Drp1). Mdivi‑1 was added to H9c2 cells for 3 h, after which, the cells were treated with sodium azide for 24 h. Cell viability was me...

Grape is important crop with high nutritional value, however there is a great need for improving the quality of the crop. Cultures were maintained in vitro on MS medium supplemented with 2.5 mg/L BAP+ TDZ 3.0 mg/ L. The effect of different doses of gamma irradiation as well as chemical mutagenesis by Sodium azide was studied. It was noted that doses up to 5 Gy helped to increase plant height fr...

Seeds of plant species from three different and distantly related genera viz. Nigella sativa L. Plantago ovata F. and Trigonella foenum graceum L. were presoaked and then subjected to 1.5, 3.0 and 4.5 mM concentrations of sodium azide for 4, 6 and 8 hours. The experiment was carried out to find a specific concentration of mutagen which can produce significant effect on distantly related crops. ...

Herein we demonstrate the sensitive nature of human blood-brain barrier (BBB) endothelial cells to sodium azide and its gaseous product. Sodium azide is known to be acutely cytotoxic at low millimolar concentrations, hence its use as a biological preservative (e.g., in antibodies). Loss of barrier integrity was noticed in experiments using Electric Cell-substrate Impedance Sensing (ECIS) biosen...
