The present invention provides phosphoryl choline derivatives of general formula (I), which are suitable to be immobilized on a solid support to provide a separation material, which bind with both high affinity and high specificity to a protein, more specifically to C-reactive protein and anti-phosphoryl choline antibodies. Said separation materials are particularly useful in the extracorporeal removal of C-reactive protein and anti-phosphoryl choline antibodies from a biological fluid of a patient for prophylaxis and/or treatment of immune dysfunctions and cardiovascular diseases. Also claimed is a device containing a column that comprises separation material made from formula (I)
wherein
L is a linker as defined in the claims;
X is selected from: -SH, -NHR3, -C=CH, -CH=CH2, -N3, -CHO.
Also claimed is a separation material of general formula (II):
wherein
A is a solid support;
Y is a group obtainable from the reactive group X.

presented. We have synthesized new crown ether-phosphate ester ionophores having high affinity for CRP. A study using proton nuclearmagneticresonance shows CRP binding to the ionophores in stoichiometric amounts. The incorporation of these crown ether-phosphate ester ionophores into poly(vinylchloride) membrane electrodes yields a CRP-sensitive electrode with sensitivity in the microgram per milliliter

Lipophilic fluorescent substances can be used to detect surface defects in materials having hydrophilic (e.g., inorganic) coatings. Use of the described methods makes surface defects appear fluorescent, while the remaining surfaces are not labeled. The disclosed methods are inexpensive, rapid, and easy alternatives to existing approaches.
