    Mar 13, 2001 · The pore-forming toxin streptolysin O (SLO) can be used to reversibly permeabilize adherent and nonadherent cells, allowing delivery of molecules with up to 100 kDa mass to the cytosol. Using FITC-labeled albumin, 10 5 –10 6 molecules were estimated to be entrapped per cell.Author: Iwan Walev, Sebastian Chakrit Bhakdi, Fred Hofmann, Nabil Djonder, Angela Valeva, Klaus Aktories, Su...

Efficient Intracellular Delivery of Native Proteins: Cell

    Apr 23, 2015 · Here, we describe a method for the efficient delivery of native proteins and other macromolecules, such as small RNAs, into primary cells. We discovered that a combination of small molecules drives the highly efficient intracellular delivery of native proteins, independent of any transduction peptide.Author: Diego S. D’Astolfo, Romina J. Pagliero, Anita Pras, Wouter R. Karthaus, Hans Clevers, Vikram Prasad,...

Boronic Acid for the Traceless Delivery of Proteins into Cells

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4900815/
    Feb 19, 2016 · The delivery of proteins and other macromolecules to an intracellular site is made difficult by cellular membranes. 1 Extensive efforts have led to the development of effective delivery systems that invoke cell-penetrating peptides, 2–5 antibodies, 6 ligands for natural receptors, 7 dendrimers, 8 functionalized polymers, 9,10 liposomes, 11 or nanoparticles. 12,13 Extant strategies …Author: Kristen A. Andersen, Thomas P. Smith, Jo E. Lomax, Ronald T. Raines

Methods for protein delivery into cells: from current ...

    https://www.portlandpress.com/biochemsoctrans/article/doi/10.1042/BST20190039/222602/Methods-for-protein-delivery-into-cells-from
    The manipulation of cultured mammalian cells by the delivery of exogenous macromolecules is one of the cornerstones of experimental cell biology. Although the transfection of cells with DNA expressions constructs that encode proteins is routine and simple to perform, the direct delivery of proteins into cells has many advantages. For example, proteins can be chemically modified, assembled into ...

    Intracellular delivery of therapeutic proteins is highly challenging and in most cases requires chemical or genetic modifications. Herein, two complementary approaches for endocytosis‐independent delivery of proteins to live mammalian cells are reported.Author: Linghui Qian, Jiaqi Fu, Peiyan Yuan, Shubo Du, Wei Huang, Lin Li, Shao Q. Yao

Cytosolic Delivery of Proteins Using Amphiphilic Polymers ...

    https://pubs.acs.org/doi/10.1021/jacs.8b10947
    Imaging studies demonstrate that the polymer–protein conjugates are successfully delivered into the cytosol of various cancer cell lines, likely through a membrane fusion mechanism. When conjugated to the delivery polymers, the activity of modified RNase A was retained and notably promoted cytotoxicity in cancer cells upon delivery to the cytosol.Author: Rapeepat Sangsuwan, Phum Tachachartvanich, Matthew B. Francis

A practical approach for intracellular protein delivery

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2151968/
    Oct 16, 2007 · Protein delivery procedure. Cells were plated in order to reach approximately 70–80% confluency the day of protein delivery experiment. For one well of a 24-well plate, 0.5–8 μg of purified protein was diluted in 100 μL of Hepes buffer (20 mM, pH 7.4) in a 1.5 mL microcentrifuge tube, under sterile conditions.Author: Claire O. Weill, Stéphanie Biri, Abdennaji Adib, Patrick Erbacher
