    • Methods for performing surface-mediated protein delivery into living cells, and fabricating protein-transfected cell cluster arrays are provided. The method comprises providing a protein-containing mixture; depositing said protein-containing mixture onto a surface at defined locations; affixing the protein-containing mixture to the surface as microspots; and plating cells onto the surface in sufficient density and under conditions for the proteins to be delivered into the cells. The protein-containing mixture comprises any suitable amino acid sequence, including peptides, proteins, protein-domains, antibodies, or protein-nucleic acid conjugates, etc., with a carrier reagent. Protein-transfected cell arrays may be used for rapid and direct, screening of protein or enzymatic functions or any given intracellular protein interaction in the natural environment of a living cell, as well as for high-throughput screening of other biological and chemical analytes, which affect the functions of these proteins.
    • 提供了将表面介导的蛋白质递送到活细胞中并制备蛋白质转染的细胞簇阵列的方法。 该方法包括提供含蛋白质的混合物; 将所述含蛋白质的混合物在限定的位置沉积在表面上; 将含蛋白质的混合物作为微滴固定在表面上; 并以足够的密度和将蛋白质递送到细胞中的条件将细胞电镀在表面上。 含蛋白质的混合物包含任何合适的氨基酸序列,包括肽,蛋白质,蛋白质结构域,抗体或蛋白质 - 核酸缀合物等与载体试剂。 蛋白质转染的细胞阵列可用于在活细胞的天然环境中快速和直接地筛选蛋白质或酶功能或任何给定的细胞内蛋白质相互作用,以及用于其他生物和化学分析物的高通量筛选,其中 影响这些蛋白质的功能。
