Antibody elution from red blood cells by chloroform and trichloroethylene.

Antibody elution by chloroform and trichloroethylene was compared with the Rubin ether method modified by Hughes-Jones for IgG antibodies and the Landsteiner and Miller heat method for IgM antibodies. After washing the cells, the chloroform and trichloroethylene method was done at 37 degrees C for 10 minutes. With this technique the eluate remained on the upper layer above the red blood cell stroma layer, while with Rubin's method the eluate remained below the cell stroma. The reported technique was as effective as the Landsteiner and Miller heat method for IgM antibodies, and a double volume of eluate was obtained.

Disulphide bonds are a requirement for adsorption of cephalosporins on the red cell membrane.

The authors studied the behavior of red cells (RBCs), treated with 2-aminoethylisothiouronium bromide (AET), against 100 serums containing cephalothin antibodies and 27 serums with cephapirin antibodies. None of the serums reacted with cephalosporin-coated RBCs that had been exposed previously to AET. The possibility of the Kell system acting as a receptor for cephalosporins was excluded. The authors discuss the significance of cysteine disulphide bonds and the tertiary or quaternary structure of red cell membrane proteins in the binding of cephalosporins to RBCs.
