<p>The present disclosure relates to compositions, systems, and methods for preserving and/or stabilizing a cell (e.g., a whole cell). A cell and/or macromolecule stabilizing composition may include a chelator, a chelator enhancing component, and optionally a base (e.g., a purine base or a pyrimidine base). A cell stabilizing method may include contacting a cell with a cell and/or macromolecule stabilizing composition. A cell stabilizing system may include a container suitable for receiving a sample containing a cell and a cell and/or macromolecule stabilizing composition. A cell may be preserved and/or stabilized under ambient conditions (e.g., without refrigeration). A cell may include a protein, a nucleic acid, and/or another biomolecule marker of cell preservation and/or stabilization. A composition may be configured to preserve and/or stabilize one or more cells for analysis by flow cytometry and simultaneously preserve and/or stabilize one or more intracellular nucleic acids for molecular analysis.</p> |
