Assay of monokines
First Claim
1. A method for determining a monokine in a blood sample which comprises the following steps:
- 1) stimulating a blood sample by incubating said sample for from about 2 to 4 hrs with a mitogenic agent;
2) directly separating blood cells from said stimulated sample obtained from step (1) to give plasma containing said mitogenic agent; and
3) determining the presence of said monokine in said plasma containing said mitogenic agent.

Abstract
The invention relates to assays of a monokine in a biological fluid, in particular in a blood sample, in particular of TNF or of IL-1. According to the present invention, the monokine in the serum or plasma obtained from whole blood stimulated with a mitogenic agent is assayed prior to any separation between the plasma (or serum) and the blood cells. According to another subject of the invention, the monokine is assayed in the case of an immunometric assay employing an oligoclonal system, consisting of several different monoclonal antibodies adsorbed on a solid phase and a non-adsorbed labeled antibody.
The invention also relates to immunoassay kits.
