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.
