Compositions and methods useful for inhibiting cell death and for delivering an agent into a cell

摘要

The invention relates to methods of salvaging a target cell from cell death, comprising contacting a target cell having a disrupted cell membrane with a specific affinity reagent-liposome conjugate in an amount effective and for a time sufficient to allow the conjugate to prevent cell death due to membrane disruption; and determining the viability of the target cell. Methods of delivering a selected agent into a damaged target cell for diagnosis and therapy are also disclosed.
