Abstract: The object of the invention is to find a simple biomarker with high reproducibility with regard to a method for evaluating the activity of the condition and progression of rheumatoid arthritis disease and provide an effective evaluation method therefor. The invention is to provide a method for determining the value of a rheumatoid arthritis-linked indicator in a subject, the method being characterized by comprising a step for measuring the amount of expression of the FAM20A gene in blood collected from the subject, a step for analyzing the measured amount of expression using a gene expression profile that is prepared in advance and correlates with the indicator and a step for estimating the value of the indicator in the subject on the basis of the analysis results.

Abstract: A coated substrate for immobilizing a biological substance etc. at high density with low background value. The substrate has a cross-linking reagent represented by general formula A—L—B (wherein, A and B represent an identical or different group which reacts with an active group of the coupling agent comprising an active group, selected from an active ester group, isothiocyanate group, isocyanate group, imidazole group, carbodiimide group or aldehyde group, and wherein L is a linking group linking A and B, selected from a straight chain alkyl group, aryl group, allyl group or alkyl group having an amide group) bound thereonto by means of a coupling agent comprising an active group. An biological substance or the like is immobilized on the substrate.
