Abstract

"PROCESSO DE SELEçãO DO SEXO DE ESPERMATOZóIDES MAMìFEROS E MéTODO DE CONTROLE DE QUALIDADE DE DOSES DE SêMEN SEXADO CONGELADO". A presente invenção permite produzir por centrifugação em gradiente de densidade, em empresas especializadas na produção e comercialização de sêmen congelado, doses de sêmen enriquecidas com espermatozóides portadores do cromossomo X ou Y, sem comprometer a capacidade fecundante destes espermatozóides. Pela presente invenção, doses de espermatozóides contendo ambos espermatozóides X e Y podem ser separadas para produzir sub populações de espermatozóides enriquecidas em portadores do cromossomo X ou Y, as quais são substancialmente puras em relação ao espermatozóide desejado e substancialmente livres do outro tipo de espermatozóide."SEX SELECTION PROCESS OF MAMMAL SPERMATOZOIDS AND QUALITY CONTROL METHOD FOR FROZEN SEX DOSES". The present invention makes it possible to produce, by density gradient centrifugation, in companies specializing in the production and marketing of frozen semen, doses of semen enriched with X or Y chromosome carriers, without compromising the fecundating capacity of these sperm. By the present invention doses of sperm containing both X and Y sperm can be separated to produce enriched sperm subpopulations in X or Y chromosome carriers which are substantially pure relative to the desired sperm and substantially free of the other sperm type.
