腫瘤的發生發展是一個復雜的過程，涉及一系列遺傳和表觀遺傳的改變。這些改變使得細胞能夠擺脫正常生長調控信號（如外部環境和內部信號）的束縛，獲得自主增殖的能力。其中，錨定非依賴性生長（Anchorage-independent growth）是細胞惡性轉化的重要標志之一，而軟瓊脂集落形成實驗（Soft Agar Colony Formation Assay）被認為是檢測細胞惡性轉化的金標準。

軟瓊脂集落形成實驗通過在半固體培養基中培養細胞，觀察其是否能夠在無錨定條件下形成集落，從而判斷細胞的惡性轉化能力。然而，這種方法通常需要3-4周才能獲得結果，嚴重拖慢研究進度，并且由于依賴人工顯微鏡計數集落，難以統一判定導致結果偏差。最重要的是傳統軟瓊脂實驗無法回收活細胞，限制了后續研究的開展。

Cellbiolabs新一代CytoSelectTM檢測系統結合熒光定量技術和改良軟瓊脂配方，全面優化了實驗流程：

CytoSelectTM細胞轉化檢測試劑盒通過高靈敏度的熒光檢測法定量細胞集落，實驗周期從3-4周縮短至1周內，顯著提高了研究效率，同時避免了人工計數的主觀誤差，尤其適合高通量樣本檢測。對于蛋白質/DNA芯片分析或癌癥疫苗開發等應用領域而言，使用專用改良軟瓊脂培養基可以輕松回收活化的轉化細胞供進一步培養和測試使用。
