Abstract

An apparatus for producing a tissue array, having at least one receiver block (1) and at least one donor block (2) that comprises tissue (3) to be investigated, is described. The donor block (2) comprises tissue (3) to be investigated, a first hollow needle (4) for creating a cavity in the receiver block (1), and a second hollow needle (5) for removing a sample from the tissue (3) and introducing the sample (3) into the cavity of the receiver block (1), being provided. For positioning of the first and/or the second hollow needle (4; 5) above the receiver block (1) and/or the donor block (2), a positioning array (11) having predefined markings, as well as a movably mounted lever, are provided for transferring the position of the markings onto a corresponding position on the donor block (2) and/or onto a corresponding position on the receiver block (1).
