Abstract: The present disclosure provides methods of transferring bio-molecular components of individual cells in a biological sample to a solid porous substate. The method including contacting the biological sample to a first side of the porous solid substrate having a plurality of interstices or pores extending contiguously from the first side to a second side, transferring and affixing the bio-molecular components of the biological sample to the interstices or pores of the solid substrate. The present disclosure further provides methods of examining or detecting one or more bio-molecular components of individual cells in a biological sample. The method includes transferring one or more bio-molecular components of individual cells in a biological sample to a solid porous substate, and detecting one or more of the bio-molecular components of the biological sample.

Abstract: The present invention provides a protein separation micro el having a first plate having a first opening; a second plate; a gel substrate formed between the first plate and the second plate; and a plurality of wells positioned at a first non-zero distance from a first edge of the gel and at a second non-zero distance from a second edge of the gel; wherein the first and second edge of the gel are opposite edges of the gel.
