Biological tissue processing substrate for fixing proteins or protein degradation products in tissue for analysis

摘要

A biological tissue processing substrate for fixing proteins in a biological tissue or degradation products of the proteins, the substrate comprising: a porous body that forms a contact surface with the biological tissue, the porous body holding in pores an enzyme for obtaining the proteins or the degradation products of the proteins from the biological tissue, wherein the proteins or the degradation products obtained by the action of the enzyme are brought into contact with a member consisting of a metal.

主权项

1. A biological tissue processing substrate comprising:
a planar support comprising a planar surface, at least part of the planar surface comprising a metal member disposed as a metal layer on the planar surface; and a porous body layer disposed on the metal layer such that a surface of the porous body layer contacts the metal layer, the porous body layer having a plurality of pores, wherein each of the plurality of pores extends in a vertical direction from the metal layer, and the pores extend through the porous body layer from the surface of the porous body layer contacting the metal layer to a surface of the porous body layer opposite the surface contacting the metal layer, wherein each of the plurality of pores comprises protease, and wherein the plurality of pores has a pore size ranging from 100 nm to 10 μm.
