Determination of antibody concentrations with the SERION ELISA classic iscarried out by the 4 parameter logistic-log-model (4 PL) which is ideal for exact curvefitting.It is based on the formula:ENEL ENOD = A +1 + eD - AB(C - ln Conc.)CS PTThe parameters A, B, C, and D are representative for the exact shape of the curve:1. lower asymptote parameter A2. slope of the curve parameter B3. turning point parameter C4. upper asymptote parameter DFor each lot the standard curve is evaluated by Institut Virion\Serion GmbH (Würzburg,Germany) in repeated test runs under optimal conditions. Time consuming and costintensive construction of the standard curve by the user is not necessary.For evaluation of antibody concentrations a lot specific standard curve as well as a lotspecific evaluation table is included with each SERION ELISA classic test kit. Theevaluation software SERION evaluate as well as the Microsoft ® Excel-based software toolSERION activity are available on request.To compensate for normal test variations and also for test run control a standard serum isused in each individual test run. For this control serum a reference value with a validityrange is determined by the quality control of the producer. Within this range a correctquantification of antibody concentration is ensured.english 15
