Activated paper as an immunoabsorbent.
Some workers when using cyanogen bromide activated paper as a solid immunoabsorbent have reported variable success in radio immuno assays. A quantitative investigation has been made of some of the factors which effect the activation of various papers with CNBr, and also of the subsequent coupling reaction with the sensitizing antigen. Different papers have been found to react in different ways, and some papers take up so little antigen that they are unsuitable for use for this purpose.
