Determination of [3H]Tdr‐Labelling Indices of Cultured Cells Grown On Detachable Chamber Slides

The in vitro effects of xenobiotic agents on the incorporation of DNA precursors was determined using a detachable chamber slide assembly. the technique presented allows for the comparative assessment of several agents, even when a limited number of cells is available. the use of a glass slide also potentiates the use of higher magnifications with a greater resultant resolution than that achievable with past methods.
