Laurell rocket technique

In contrast to the Laurell rocket technique, this method is not used for quantitative determinations. Rather, it is applied to detect heterogeneity in seemingly homogeneous protein fractions, obtained by gel chromatography or ion exchange chromatography. A set of wells is punched in a... 

It can also be determined immunochemically by e.g. radial immunodiffusion or the Laurell rocket technique. 

The immunoglobulins present in the serum in the greatest amounts (IgG, IgA and IgM) can be measured by a variety of immunochemical tests using antiserum directed against one particular class of immunoglobulin (anti-IgG etc.). The techniques that can be used include radial immunodiffusion, automated immune precipitation and the Laurell rocket technique. Because of its much smaller concentrations, IgE is usually measured by radioimmunoassay. 

TBG can be determined by immunochemical methods, e.g. by the Laurell rocket technique. If the total serum thyroxine in the sample is known, the amount of the free hormone can be calculated.
