134. Knor S, Modlinger A, Poethko T, Schottelius M, Wester HJ, Kessler H. Synthesis of novel 1,4,7,10-tetraazacyclodecane-1,4,7,10-tetraacetic acid (DOTA) derivatives for chemoselective attachment to unprotected polyfunctionalized compounds. 2007;13:6082-90

The most common and commercially available BFC comprise esters (-nitrophenyl, pentafluorophenyl, -hydroxysuccinimide, sulfo--hydroxysuccinimide), isothiocyanates, maleimides, hydrazides, α-haloamides for the reaction with nucleophilic functional groups (-NH2, -SH, -OH) of vector molecules and formation of amide, urea, thiourea, Schiff-base, or thioester bond []. Methods have been developed for the conjugation with peptides by solid-phase peptide synthesis (SPPS) resulting in defined position and number of chelate moieties. The outcome of the conjugation in solution wherein peptides and proteins comprise several reactive sites is very often a mixture of bioconjugate molecules with various content of the chelator. Such heterogeneity may cause the interpretation ambiguity of the performance of such imaging agents. Regioselective conjugation to antibodies was achieved by enzymatic reaction with lysine and glutamine residues using bacterial and human tissue transglutaminase as catalysts [].

In general, high density grades of polyethylene have densities up to 0.97 g/cm^. Low density grades are as low as 0.91 g/cm^. Typically, the high-density material is more linear and consequently more crystalline. As might be expected, this higher crystallinity permits use at temperatures up to 130 C degrees with somewhat better creep resistance below that temperature. Low density polyethylene has less stiffness than the high density type. Blends of the two types are common.

Nanocomposites: synthesis, structure, properties and …

After its experimental preparation in the 1930s, the application in high frequency radar cables during World War II, gave impetus to its commercial production. This thermoplastic is available in a range of flexibilities depending on the production process. High density materials are the most rigid. The polymer can be formed by a wide variety of thermoplastic processing methods and is particularly useful where moisture resistance and low cost are required. Polyethylene is limited by a rather low temperature capability (200-250 F) but is manufactured in billions of pounds per year.
