Factors influencing the agglutination of red blood cells, red blood cell stroma, and lymphocytes.

In a recent review of the literature (1,2), many of the problems dealing with cellular agglutination caused by ricin are presented and discussed. Although this phenomenon was first described in 1888 by Stilhnark, reactions involved in the agglutination of cells are poorly understood. The present report is concerned with factors which affect agglutination. Data are presented which show that erythrocyte, erythrocyte stroma, and lymphocyte agglutination may be influenced by a large number of different materials and conditions.
