The invention relates to a method of isolating a T cell that expresses a T cell receptor capable of binding specifically to an antigen presented by a cancer cell in association with an MR1 molecule. The method comprises the steps of (a) providing a preparation of T cells, (b) contacting the preparation with cancer cells expressing MR1 protein; (c) isolating a T cell that is specifically reactive to said cancer cells. The invention further relates to a method of preparing a T cell preparation expressing select MR1 recognizing T cell receptors from transgene expression vectors, the use of such T cell preparations in treatment of cancer, and to collections of MR1 reactive T cell receptor encoding nucleic acids and cells.

The present disclosure relates in some aspects to methods for preparing biological samples for in situ analysis of one or more analytes, wherein the biological sample has been previously affixed to a substrate, which is not compatible with in situ analysis, for example, due to the absence of positional markers and/or fiducial markers and/or a region suitable for in situ signal detection on the substrate.

A cancer test device (1) is provided with: an application unit (40) for applying a staining agent (45), which can selectively stain a product of a cancer-relating gene in a living cell a chromatic color, onto a group of living cells; an imaging unit (10) for imaging the group of living cells having the staining agent (45) applied thereto; and a determination unit (52) for determining the level of malignancy of cancerization of the group of living cells on the basis of the state of the stained expression pattern of the cancer-relating gene in the group of living cells in an image obtained by the aforementioned imaging.
