The present invention relates to a block copolymer, and to a block copolymer including an aromatic vinyl-based polymer block, a conjugated diene-based polymer block and a coupling agent linking group, wherein the conjugated diene-based polymer block includes a hydroxyl group, and the hydroxyl group content is 0.5 mol % to 12.0 mol % based on the double bond content of a conjugated diene-based monomer unit, a method for preparing the same, and an asphalt composition including the same.

This disclosure relates to methods for obtaining immobilized enzyme preparations, in particular to a preparation and application of a novel active conjugate of an enzyme with a polymer carrier. Said conjugate possesses the properties of the known Longidaza® drug and inhibits hyperplasia of connective tissue, and presents anti-inflammatory action, and can be used for manufacturing stable, active and safe in use long-acting drugs in the form of a suppository, ointment, injection, cosmetic cream, and for making veterinary drugs. These methods include conjugation of hyaluronidase with a water-soluble copolymer using the carbodiimide or azide conjugation method. The conjugation is carried out with the use of a copolymer N-oxide 1,4-ethylene piperazine, (N carboxymethyl)-1,4-ethylene piperazine or its hydrazide, and 1,4-ethylene piperazine of general formula: ##STR00001## where n is from 40% to 90% of the total number of units; m is from 3% to 40% of the total number of units; and n+m+1=100%.

A method of immobilizing an oligonucleotide on a polypropylene surface involves oxidizing at least a portion of the polypropylene surface, and contacting an amine-terminated oligonucleotide with the oxidized polypropylene surface to immobilize the oligonucleotide to the oxidized polypropylene surface. The method of immobilizing labelled ssDNA on a polypropylene surface is useful in a hybridization assay.
