Strategy For Constructing Gene Knock-in Cell Lines

Experiment Tags: Knock-in Cell Lines, Knock-in

Experiment Summary: Because the success of knock-in cell line construction is influenced by various factors, including the length of the knock-in gene fragment, homologous recombination efficiency, and cell line type, which can impact editing efficiency, this also makes the knock-in technology challenging. This article introduces the principles of constructing KI cell lines and the details that need to be paid attention to.

Protocol for Quantitative Analysis of Mitochondrial Membrane Potential Using JC-1

Experiment Tags: Mitochondrial membrane potential, ΔΨm, JC-1 assay, apoptosis, mitochondrial dysfunction, flow cytometry, fluorescence microscopy, cell biology protocol

Experiment Summary: This protocol describes a JC-1–based method for assessing mitochondrial membrane potential (ΔΨm) in cultured cells. By comparing red and green fluorescence signals generated by JC-1 aggregates and monomers, respectively, changes in ΔΨm can be detected as an early indicator of mitochondrial dysfunction and apoptosis. The procedure applies to both flow cytometry and fluorescence microscopy and includes detailed guidance on cell preparation, staining, data acquisition, and analysis.
