The inhibition of cell growth can be gauged by, ยกตัวอย่างเช่น counting the number of cells contacted with compounds of interest, comparing the cell proliferation with otherwise identical cells not contacted with the compounds, or determining the size of the เนื้องอก that ครอบคลุม the cells. The number of cells, as well as the size of the cells, can be readily assessed using any method known in the art (ยกตัวอย่างเช่น trypan blue exclusion and cell counting, measuring incorporation of 3H-thymidine into nascent DNA in a cell).
