Soft agar colony formation assay is established to estimate the anchorage-independent growth ability of cells. In this assay, a bottom layer of agar with complete media is poured and solidified first, followed by an upper layer containing a specified number of cells suspended in medium-agar mixture. After two weeks of incubation, the number of colonies will be counted, serving as an indicator of malignancy of tumor cells.
软琼脂集落形成试验用于评估细胞的不依赖贴壁生长能力。在此试验中,首先倒入含有完全培养基的底层琼脂并使其凝固,接着加入上层琼脂,其中含有悬浮在培养基 - 琼脂混合物中的特定数量细胞。孵育两周后,将对集落数量进行计数,作为肿瘤细胞恶性程度的指标。
