This assay is to provide NCI-H441-based In Vitro (3)H-thymidine Incorporation Assay (Cell Proliferation) to accelerate our client's oncology projects. The assay will be customized according to the specific requirements. Please contact our scientists to discuss more details.

NCI-H441

Human

NCI-H441 [H441] cells were isolated in 1982 from the pericardial fluid of a male patient with papillary adenocarcinoma of the lung. Use these cells as a transfection host for expression of pulmonary surfactant protein (SP-B).

In Vitro (3)H-thymidine Incorporation Assay (Cell Proliferation)

The 3H-thymidine incorporation assay is one such assay that can detect newly synthesized DNA in cells. Cultured cells are mixed with 3H-thymidine (radioactive) and kept for a desired incubation period. Newly replicated DNA strands can incorporate 3H-thymidine during mitosis. A scintillation counter is necessary to detect the output. Direct measurement of proliferating cells is the main advantage of this assay. However, use of harmful radioactive substances and need of special equipment are considered as main disadvantages.

Cell Viability/Cytotoxicity and Antiproliferative Assays

Uncontrolled proliferation is one of the main features of cancer cells. Cell-based in vitro assays are employed to determine whether test molecules possess direct cytotoxic/antiproliferative effects in cancer cells.
