COA Handling Instructions

L67 (DNA Ligase Inhibitor) is a competitive DNA ligase inhibitor that effectively inhibits DNA ligases I/III (both IC50 are 10 μM). L67 (DNA Ligase Inhibitor) can cause nuclear DNA damage by reducing levels of mitochondrial DNA and increasing levels of mitochondrially-generated ROS. L67 (DNA Ligase Inhibitor) also activates the Caspase 1-dependent apoptosis pathway in cancer cells, can be used in cancer research.

Description

L67 (DNA Ligase Inhibitor) is a competitive DNA ligase inhibitor that effectively inhibits DNA ligases I/III (both IC50 are 10 μM). L67 (DNA Ligase Inhibitor) can cause nuclear DNA damage by reducing levels of mitochondrial DNA and increasing levels of mitochondrially-generated ROS. L67 (DNA Ligase Inhibitor) also activates the Caspase 1-dependent apoptosis pathway in cancer cells, can be used in cancer research[1][2].

In Vitro

L67 (10, 15 μM; 24 h) promotes nuclear DNA damage and (0-50 μM) increases level of mSOX by inhibiting mitochondrial LigIIIα in HeLa cells[1].
L67 (10 μM; 24 h) induces changes in mitochondrial function that causes a reduction in OCR and mitochondrial DNA, and abnormal mitochondrial morphology in HeLa[1].
L67 (10, 100 μM; 24 h) induces apoptosis in cancer cells[1].
L67 (0-30 μM; 24 h) selectively induces cell death in cancer cells by activating a caspase 1-dependent apoptotic pathway[1].

Cell Viability Assay[1]

Cell Line: HeLa cells
Concentration: 10, 15 μM; 0-50 μM
Incubation Time: 24 h
Result: Increased the formation of nuclear γH2AX foci and steady state levels of γH2AX when at 10 or 15 μM. (γH2AX: a sign of DNA double-strand breaks).
Resulted in a concentration (0-50 μM)-dependent increase in mSOX (mitochondrial superoxide) levels. (mSOX is a major cause of the cellular oxidative damage).

Cell Viability Assay[1]

Cell Line: HeLa cells
Concentration: 10 μM
Incubation Time: 24 h
Result: Reduced oxygen consumption rate (OCR) approximately 20%.
Resulted in about a 25% reduction in mitochondrial DNA.

Apoptosis Analysis[1]

Cell Line: HeLa cells
Concentration: 10, 100 μM
Incubation Time: 24 h
Result: Result:Induced apoptosis, and at 100 μM with apoptotic cells constituting about 50% of the HeLa cell population.

Cell Viability Assay[1]

Cell Line: HeLa cells
Concentration: 0-30 μM
Incubation Time: 24 h
Result: Activates a caspase 1-dependent cell death pathway in cancer cells.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
