Abstract: | A method to quantitate lectin activity based on hemagglutination assay in microtiter plates is described. In addition to the normal method of visual titer evaluation an electronic particle counter is used for counting of nonagglutinated cells in the microtiter wells; this allows a rapid, quantitative determination of the amount of lectin required to agglutinate 50% of the countable single cells. It is also recommended that counting results should be related to a standard curve of concanavalin A to improve the reproducibility of the assay. |
