Journal of Macromolecular Science: Part A - Chemistry, 1977
Abstract Despite the fact that polyvinyl chloride) (PVC) has occupied the most important position among general-purpose plastics, its industrial applications are limited due to its inferior thermal stability and mechanical properties. Many studies have been conducted to remedy these disadvantages.

Erythrocyte Membrane: Chemical Modification
Science, 1965Erythrocytes treated with 1-fluoro-2,4-dinitrobenzene become permeable to Na + and K + , but not to small water-soluble nonelectrolytes or hemoglobin, and eventually lyse in isotonic buffer. Erythrocytes treated with 1,5-difluoro-2,4-dinitrobenzene become permeable to Na +

Chemical Modification of siRNA
Current Protocols in Nucleic Acid Chemistry, 2009AbstractThe ability to manipulate the RNA interference (RNAi) machinery to specifically silence the expression of target genes could be a powerful therapeutic strategy. Since the discovery that RNAi can be triggered in mammalian cells by short double‐stranded RNAs (small interfering RNA, siRNA), there has been a tremendous push by researchers, from ...

Abstract Chemical modification is one of the most useful methods of identifying the functional groups of a protein. Whether or not the various types of amino acid side chains are involved in a protein’s function can be determined readily by whether or not chemical modification of that type of amino acid affects the function.

Chemical Modification of Alpha Crystallin
Experimental Eye Research, 1993Calf lens alpha-crystallin was isolated and the lysine residues were extensively modified with a variety of chemical agents. The effect of these modifications on elastase inhibitor activity, apparent molecular size, antibody reactivity and solubility were determined. The addition of either a methyl group or a threose residue did not alter the charge on

Chemical Protein Modification through Cysteine
ChemBioChem, 2016AbstractThe modification of proteins with non‐protein entities is important for a wealth of applications, and methods for chemically modifying proteins attract considerable attention. Generally, modification is desired at a single site to maintain homogeneity and to minimise loss of function.

Chemical modifications of pancreatic colipase
Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1977Abstract Some chemical modifications of porcine pancreatic colipase and their effects on its biological activity have been studied. Modification of the free carboxylic groups with glycine methyl ester using 1-cyclohexyl-3-(2-morpholinoethyl)-carbodiimide-metho- p -toluene sulfonate as activating agent resulted in complete loss of colipase activity. 4
