Publication Information Keystone View Company This district is taking people who prefer it out of the more crowded central sections of the city's residential areas Creator James C. The strongest reaction was observed against blood group O Rh+ (O+).Title Cuba - Province of Oriente - Santiago De Cuba: Vista Alegre, the new residential district fast growing up with fine homes on the northern edge of the busy city which is the provincial capitol and second port city of Cuba. Positive reactivity against human erythrocyte antigens A, B and O was demonstrated in de-lipidated supernatants from the egg yolks of immunised hens. The highest titres were observed four weeks after the first immunisation, and these remained stable for up to seven weeks for the intravenous route. The haemagglutination assay was used to evaluate the dynamics of the production of IgY antibodies against human erythrocyte antigens, and single radial immunodiffusion was used to evaluate the amount of total IgY in de-lipidated supernatants from egg yolk. To evaluate the humoral immune response of hens immunised with human red erythrocyte antigens, 22 White Leghorn hens were kept in cages and immunised with total red blood cells or stroma of the human rhesus positive (Rh+) system (D antigen) by weekly intramuscular and intravenous injections, without the use of an adjuvant. Furthermore, because of the phylogenetic distance between birds and mammals, avian antigens have a very specific immune response to highly conserved antigens of mammals, such as human erythrocyte antigens.

This technology has become a worthwhile alternative to the blood-dependent techniques. The fact that antibodies can also be detected in the yolk of eggs laid by immunised hens, led to the development of yolk antibody technology (IgY-technology) as an alternative method that is less stressful to animals. Polyclonal antibodies, widely used in research and diagnostics, are conventionally isolated from the blood of immunised mammals, especially rabbits.
