Przykłady antigen

• Immunoblot analysis has revealed striking specificity of antigen components in the 3 sandfly species studied.

• Liposomes are lipid membrane particles that serve as vehicles or delivery systems for vaccine antigens.

• Subsequent experiments were performed using standard methods plus antigen recovery because this enhances the quality of the immunolabelling.

• Determining the paternal antigen status through a peripheral blood assay is an important step, which should be undertaken early in the pregnancy.

• To some extent, the difference between the types of antigen used makes a fair comparison between results difficult.

• Potentially harmful antibodies directed at fetal antigens are thereby 'mopped up'.

• As tumour growth progresses, parts of the tumour can become necrotic and soluble t u m o u r antigens are released.

• The major challenge in the development of antischistosome vaccines is to use defined antigens to stimulate an appropriate immune response that leads to resistance.

• It must be borne in mind always that the efficacy of a vaccine depends on more than the primary amino acid sequence of the antigen.

• Evidence for cross-species efficacy of homologous antigens will be discussed.

• The donor's antigens can be typed in several different ways.

• Conversely, antibody production is controlled by the probability of antibodies (or antibody-producing cells) encountering bacteria (or being presented with antigens derived from these pathogens).

• If the participation of the former type of antibody were predominant or exclusive, sera would show similar reactivities against all antigens.

• Furthermore, the preparation of carbohydrate antigen still depends on extraction from crude antigens.

• However, immunodiagnosis using specific antigens is also useful.
