BACKGROUND AND OBJECTIVES Bacterial contamination represents the major infectious hazard associated with transfusion of platelet concentrates (PCs). As bacterial screening of PCs is not mandatory in Germany, the BactiFlow flow cytometry test has been introduced as a rapid detection method to increase product safety. MATERIALS AND METHODS During a period(More)
OBJECTIVE Two new protocols for the MCS 3p cellseparator (Haemonetics) for automated collection of blood components were evaluated. MATERIAL AND METHODS Two units of FFP and one unit of buffy coat free red blood cells (RBC) in additive solution (PAGGS-M) were produced with the D-RBCP protocol. The RBCP-F protocol included additional in-line filtration of(More)
In this study we characterized the human T cell-reactive sites of the major cow dander allergen, Bos d 2, a member of the lipocalin protein family. We showed that Bos d 2 contains only a limited number of epitopes. This is in contrast to many other allergens, which usually contain multiple T cell epitopes throughout the molecule. The epitopes of Bos d 2(More)
The relationship between the molecular structure of allergenic proteins and the allergenic determinants is one of the central issues in allergology. We report here that the natural preparation of Bos d 2, a mammalian lipocalin allergen, comprises three molecular variant proteins of 17,829, 17,781, and 17,800 Da. When cDNA of Bos d 2 (Genome Sequence Data(More)
Major respiratory allergens of dogs, mice, rats, horses and cows belong to the lipocalin group of proteins. The sequence identity of lipocalins is often less than 20%, but they contain between one and three structurally conserved regions and their three-dimensional structures are similar. Lipocalins share common biological functions, predominantly related(More)
Although payment of blood donors is rejected by the WHO, the FDA, the EU, and the Red Cross (RC), in Germany, monetary compensation of expenses is permitted not only for plasmapheresis but also for whole blood donation. The structure and organisation of the institutions ensuring the blood supply in Germany and the pertaining aspects of blood safety will be(More)
BACKGROUND Lately, renewed interest has arisen in the new forms of allergen immunotherapy because they may offer alternatives for drug treatment. OBJECTIVE The purpose of this study was to develop a well-characterized preparation of the main respiratory cow dander allergen, Bos d 2, with attenuated allergenic activity. METHODS The immunologic(More)
The immunological characteristics of an important group of animal-derived allergens, lipocalins, are poorly known. To explore the immunology of the lipocalin allergen Bos d 2, several mouse strains with different H-2 haplotypes were immunized with the allergen. Only the BALB/c mouse mounted a distinct humoral response against Bos d 2. The proliferative(More)
BACKGROUND Remuneration for blood donors, in the way as presently handled by governmental and communal blood transfusion services in Germany, is not generally accepted. It is feared that donors are recruited with increased risk to transmit infectious diseases, especially AIDS. Alternative incentives are discussed. After the so-called AIDS scandal in(More)
