A device for taking and optionally processing a sample, includes (i) a housing containing a porous matrix that can receive the sample, (ii) a stopper that can be connected to the housing in a tight manner and including a piston that ensures the tight closing of the housing, compressing the porous matrix or the sample, and (iii) a storage receptacle that can be connected to the housing, can receive the sample that has passed through the porous matrix, and includes at least one conduit connecting the inside of the receptacle to the outside, once the porous matrix or the sample is compressed. The device also includes a seal between the stopper and the storage receptacle. The stopper closes the storage receptacle in a tight manner when the stopper and the storage receptacle are connected to the housing.

Device for taking a sample and sample analysis system comprising such a device

A method for the in vitro immunization of human B lymphocytes, comprising culturing a total mononuclear cell population of human peripheral blood in the presence of an antigenic composition comprising at least one antigen covalently bonded to both: (i) a Tat protein or a Tat fragment capable of oligomerization and (ii) a ligand of a surface molecule specific to the antigen presenting cells; a method for producing antigen-specific human antibodies derived from said in vitro immunization method.
