Abstract: Provided is a method, and pharmaceutical composition, to treat or prevent cyanide poisoning and/or methylmercaptan poisoning comprising administering to a subject in need an effective amount of tetrathionate by intramuscular injection or by intranasal administration. Also provided is a method for detecting the presence of tetrathionate in a sample by reacting it with cyanide and measuring the resulting thiocyanate with ferric nitrate.

Abstract: This disclosure concerns materials for detecting and removing gaseous chemical agents (e.g., cyanide, cyanogen, sulfide, nitrite, nitric oxide, and combinations thereof), devices including the materials, and methods of making and using the disclosed materials. Embodiments of the disclosed materials include a support material impregnated with cobinamide and/or a cobinamide derivative.

Abstract: Compositions comprising nitrosyl-cobinamide are provided. Also provided are methods for treating hypertension, which comprise administering therapeutically effective amounts of nitrosyl-cobinamide. Also provided are methods for producing nitrosyl-cobinamide.

Abstract: The invention is a method for the isolation of molecules of interest using tubes in which at least a portion of the inner walls of the tube are coated with microbeads that are coated with a capture reagent to bind the molecule of interest. The microbeads may be glass or polymer beads. The invention is a method and apparatus for preparation of the tubes for use in the method of the invention. The invention is a method for determining ratios of guanine nucleotides bound to guanine-nucleotide binding proteins.

Abstract: Compositions comprising nitrosyl-cobinamide are provided. Also provided are methods for treating hypertension, which comprise administering therapeutically effective amounts of nitrosyl-cobinamide. Also provided are methods for producing nitrosyl-cobinamide.

Abstract: The invention features methods for measuring the total amounts of G protein-bound GDP and GTP in mammalian cells and tissue. The method of the invention is advantageous over conventional methods in that the cells need not be exposed to phosphate-free growth conditions, which can adversely affect the accuracy of the GTP determination. Moreover, the method does not require exposure of the cells to radiolabelled phosphate in the growth medium. Standardized amounts of G protein-bound GDP and GTP are determined relative to non-nuclear cellular protein content or cellular DNA content, allowing comparison of results across different cell types. The method is particularly applicable to the detection of Ras protein bound GTP and GDP.
