Patent Images
1. A method of detecting pyrogens in a sample comprising the steps of:
- a) combining a pyrogen-free monocyte-containing reagent and the sample to be tested in a pyrogen-free assay system, wherein the assay system comprises at least one surface treated with a pyrogen-free antibody to a cytokine; and
b) assaying the assay system for the presence of cytokine bound to the antibody on the surface;
whereby an elevated level of cytokine bound to the surface indicates the presence of pyrogens in the sample tested.

Abstract
The invention concerns an improved pyrogenicity test for use in automated immunoassay systems, in which a sample is incubated with a monocyte-containing reagent in a pyrogen-free assay system preferably comprising a surface coated with pyrogen-free anti-cytokine antibodies. The invention also concerns pyrogen-free assay systems coated with pyrogen-free antibodies for use in these tests. The invention also relates to a test to measure the basal production of endogenous mediators of the inflammatory response by leukocytes and a method of measuring the capacity of a leukocyte to respond to a stimuli.
