摘要

Said reagent satisfies the formula i c - after: & br / (see appended drawing in bopi) & br / & & br / in which l represents a binding substance capable of binding specifically to a ligand to be detected in a fluid, or to a receiver of the ligand; r is a reactive group, ensuring the connection between the neck and the substance l, which group r is able to react by the addition, substitution, or any other reaction with the substance l; s is the support of the reactive group, and is of the type (xh) x - y (y) - (z) z, in which x represents a nitrogen atom, y represents a group or a group so2, z represents a group ch2, x and y represent 0 or 1, and z represents 0, 1 or 2; the neck is a molecule able to produce a coloration; & br / s represents one or more groups solubilisers type so3 x ′, coox ′ or nx '+, in which x' represents a hydrogen atom or an alkali metal atom; n is 0 or 1.
