Tenders are invited for purchase of sodium hydrosulfide (sodium bisulfide) to be used in the scavenger system.
The most commonly used are Southern blot analysis; bisulfide genomic DNA sequencing; restriction enzyme-PCR, MSP; and the methylation-sensitive single nucleotide primer extension.
Two-thirds of [H.sub.2]S molecules dissociate into hydrogen ions (H+) and bisulfide ions (HS-) under physiological conditions.
Zinc oxide (ZnO), stearic acid (HSt), 2-mercaptobenzothiazole (accelerator M), diphenyl guanidine (accelerator DM), tetramethylthiuram bisulfide (accelerator TMTD), N-phenyl-2naphthylamine (antiaging agent D), sulfur (S), and other chemical agents were commercially available.
For these low-till or no-till systems, scientists are using biotechnology to develop crop varieties with increased tolerance for herbicides .Non selective herbicides, toxic to all plants are used where complete control of plant growth is required.Other popular inorganic herbicides includes; ammonium sulfamate, carbon bisulfide, sodium chlorate, sulfuric acid solutions and solutions and formulations containing borate.
