Provided herein are methods of identifying a target protein in a tissue sample that include delivering a plurality of probes to a tissue sample, where a probe of the plurality of probes comprises an antibody conjugated to an oligonucleotide having a sequence, where the antibody specifically binds to the target protein in the tissue sample; amplifying the oligonucleotide to generate an amplicon comprising copies of the oligonucleotide; detecting all or a portion of a copy of the oligonucleotide in the amplicon; and using the detected sequence to identify the target protein in the tissue sample.

An apparatus comprising a magnetic assembly and methods for operating the apparatus are provided. The magnetic assembly may be used to manipulate molecules in a liquid preparation, for example to isolate or separate the molecules from the liquid. The magnetic assembly may be used to wash and/or isolate nucleic acid molecules of interest from a liquid preparation.

Provided herein are methods and systems for biochemical analysis, including compositions and methods for processing and analysis of small cell populations and biological samples (e.g., a robotically controlled chip-based nanodroplet platform). In particular aspects, the methods described herein can reduce total processing volumes from conventional volumes to nanoliter volumes within a single reactor vessel (e.g., within a single droplet reactor) while minimizing losses, such as due to sample evaporation.
