Patent number: 6317702Abstract: The present invention relates to a method for instrument determination of measured variable L(t) which changes with time, the intention being to determine the maximum rate value of L(t) in a region with a linear reaction profile, and the time as well as the duration of the reaction time window being variable with the linear region and depending on the nature of the reaction and the reaction conditions. Specifically, the present invention relates to the determination of protein concentrations with the aid of light scatter, which is produced by specific antibodies, in homogeneous solutions. In particular, the invention relates to reactions which take place slowly and have a largely linear profile over a relatively long time, the rate of formation of antigen-antibody complexes in the linear section of the reaction (VMaxLin) being determined as the measured variable.Type: GrantFiled: February 11, 2000Date of Patent: November 13, 2001Assignee: Dade Behring Marburg GmbHInventor: Jürgen Patzke
