Two-site ELISA method for the measurement of total Protein S (free or complexed with C4b-BP), on human plasma or any biological sample where protein S must be measured. This assay is designed with two conformational monoclonal antibodies, calcium dependent, the first one for coating the microplate (immunocapture) and the second one, labelled with horseradish peroxidase (HRP), for revelation. The method is a one-time assay (total assay time 1h05 min). The assay calibrator is standardised with the NIBSC international standard. The kit includes two controls (normal and abnormal).

Note: a minimum order of 20 kits is required for this item.
