Abstract From the Canadian patent

The method for detecting the sulfidoleukotrienes sLT of the group LTC4, LTD4 and LTE4 by a single immunoenzymatic ELISA assay is based on the interaction between one or several monoclonal anti-sLT antibodies and an sLT conjugated to a revealing enzyme. A biological sample, wherein a content of sLT is assumed is contacted, with a monoclonal anti-sLT antibody bound to a carrier. After the sLTs present in the sample are bound to the said antibody a, conjugate of an sLT with a revealing enzyme is added to the charged carrier. Finally the amount of the conjugate bound to the carrier is evaluated, which amount is in an inverse correlation with the sLT bound to the carrier. The method is useful …
