Derivatized nylon fibers

There are several methods described in the literature which enable antigen-specific physical separation of immunocompetent cells antigen-coated columns, derivatized nylon fibers, gradient techniques and electronic cell sorters. These methods will now be considered ...

Polyamides are well-known industrial products having applications in many areas (7). For instance, the Nylon polymers (water-insoluble polyamides) are widely used in fibers. A water-soluble poly(aminoamide), derived from adipic acid and diethylene triamine, is the precursor to a well-known industrial resin (2). This poly(aminoamide) is currently produced by a chemical reaction at elevated temperatures which is accompanied by the formation of some branched structures. Subsequent derivatization of this polyamide produces a water-soluble resin, known for its ability to impart wet strength to paper and paper products (2a, 2b) and shrink proofing to wools and other textiles (2c).
