NCI-H187 expresses elevated levels of the 4 biochemical markers of SCLC: neuron-specific enolase, the brain isoenzyme of creatine kinase, L-dopa carboxylase and bombesin-like immunoreactivity.

N-myc is not amplified.

They express easily detectable levels of p53 mRNA compared to levels found in normal lung.

Cultures can be maintained by addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation of the suspension with subsequent resuspension in fresh medium. Add medium as the cell density increases.
