LIGHT STABLE PHYSICAL DEVELOPER

摘要

A light-stable physical developer comprising a solution of silver ions, a desensitizing agent and a reducing agent. A method for the detection of one or more components of an aggregate formed between at least one specific binding agen t and its corresponding bindable substance by labelling at least one component of said aggregate with a marker and contacting said aggregate with said light-stable physical developer, whereby under influence of the marker a metal particle is formed which can b e detected. Further the invention also relates to products, e.g. a test-kit adapted for carrying out the above mentioned method.
