Reverse protein delivery into cells on coded microparticles
First Claim
Patent Images
1. A method for delivering proteins in cells, comprising:
- contacting a first micro-carrier substrate having a unique identification code with a first protein-containing mixture under conditions to allow the protein to attach to the micro-carrier substrate, wherein the first protein-containing mixture comprises a protein of interest, a carrier reagent, and a helper reagent; and
contacting the first micro-carrier substrate having the protein of interest attached thereto with cells under conditions sufficient for the cells to adhere to the surface of the micro-carrier substrate and for the cells to uptake the protein of interest, wherein the code on the first micro-carrier substrate includes at least one rare earth element.

Abstract
Systems, methods and kits that utilize uniquely coded microparticles for performing protein assays are provided. The uniquely coded microparticles are used as a substrate for reverse protein delivery into cells. The microparticles and methods offer the possibility of studying the biological functions of either a single protein of interest in multiple cell types per assay or multiple proteins in a single cell type.
