description

Abstract Background immunoradiometric assay (IRMA) is one of the principal methods used for the analytical determination of neuron specific enolase (NSE) concentration. We studied the influence of temperature on the calibration curves obtained by this method, and a physicochemical justification based on two theoretical models is proposed. Material and methods we used a commercially available RIA kit for NSE and a gamma counter. Data was analysed using Statistical software. Results and discussion activity bound to the antibody increases with temperature, producing results that are consistent with two modifications to the four parameter and Langmuir equations. Conclusions the two models used successfully reproduce the results, with the adsorption model being preferable due to its greater simplicity and clearer physical significance.
