The present invention is directed to conjugates for biorecognition comprising (i) an carbohydrate backbone structure (PO) of 5 to 20 monosaccharide units, (ii) oligosaccharide biorecognition groups (Bio) of 1 to 10 monomer units, (iii) a bifunctional spacer groups of the formula -(y)p-(S)q-(z)r-, wherein S is a spacer group, p, q and r are each 0 or 1, whereby at least one of p and r is different from 0, and y and z are chemoselective ligation groups, which covalently link a said Bio group to said backbone structure, and the degree of conjugation, indicating the average number of covalently attached Bio biorecognition groups per monomer unit of the backbone, being from 0.2 to 1. The invention is also directed to processes for their preparation, intermediates for use in the process as well as use of said conjugates, especially for inhibiting pathogenic bacteria.
