Water and methanol adsorption on a series of organic complexes of montmorillonite

Creator:: Carter, Loren Sheldon
Abstract:: Water and methanol adsorption isotherms at 25° and 37° C. were determined on a series of organo-bentonite clays. The clays differed in the length of the carbon chain attached to the amine adsorbed in the cation exchange position. The amines used had carbon chains of 4, 6, 8, 10, 12,...

Mass spectrometric analysis of bovine neurofilament proteins NF-L, NF-M, and NF-H : peptide mapping, phosphorylation and alkylation site identification

Creator:: Mixon, April E.
Abstract:: Neurofilament proteins are intermediate filaments found in the neuronal cytoskeleton. Phosphorylation of these proteins is considered important for the assembly and stability of the filaments. Accurate molecular weights have been difficult to measure, largely because the high degree of phosphorylation results in M[subscript r]'S that are significantly greater than dictated...
