| abstract |
The invention provides a cell library for use in detecting protein expression comprising a plurality of cells, wherein each cell comprises a polynucleotide sequence encoding a detectable marker integrated into the genome of the cell in frame with a protein coding gene selected from a set of target genes, wherein the library comprises more than one cell tagged at each target gene, as well as a cell library for use in detecting protein interactions between a protein of interest and a set of target proteins and a cell library for use in detecting protein modifications. The invention also provides methods of constructing a cell library for use in proteomics, as well as methods for sequencing integration sites of a donor sequence inserted into the genome of a cell. Also provided are systems for analysis of proteins in a cell and kits comprising vectors for tagging a population of cells and for performing proteomics studies. |
