Intrasplenic immunization with minute amounts of antigen.
There are two ways to raise antibodies to minute amounts of immunogen. The first is in-vitro immunization in which the immunogen is presented to a spleen cell culture and about a week later cell fusion for hybridoma production is attempted. The second, and the subject of this review, is intrasplenic immunization, in which the immunogen is deposited into the spleen tissue and the animal itself takes care of growing the spleen cells. Both of these techniques are appropriate when only small amounts of immunogen are available. Intrasplenic immunization, however, requires less laboratory work and there is a decreased risk of contamination, often a problem with hybridoma cultures. The experience of intrasplenic immunization shows that it is the method of choice for immunization with nanogram amounts of immunogen. A successful outcome, however, requires that the immunogen is immobilized on a carrier. This review by Ove Nilsson and Anders Larsson will focus on the various types of matrix which can be used as carriers and on the procedures for transferring these carriers into the spleen tissue.
