A method for detecting a glycoprotein using a solid support is disclosed where the glycoprotein is oxidized by periodate, polyacrylic polyhydrazide which is a copolymer having repeating units possessing a hydrazide group and repeating units possessing hydroxyl groups is coupled to the oxidized glycoprotein and a glycoenzyme or radioactive compound containing aldehyde groups or activated ketone groups is coupled to the polyacrylic polyhydrazide which allows for detection of the glycoprotein. The glycoprotein may be directly attached to the solid support or may be bound to an antigen which is immobilized on the solid support.

Polyacrylic hydrazides and their applications as glycoprotein reagents

An acrylic monomer which is an amino sugar alcohol whose primary or secondary amino group has been derivatized by an acryloyl or a methacryloyl function. The amino group can be linked to any carbon of five or six-carbon sugar alcohols. The acrylic monomer has the formula: ##STR1## where R.sub.1 is H, CH.sub.2 OH or (CHOH).sub.m CH.sub.2 OH, m being 1 or 2;
