Propidium iodide (PI) is often used for cell cycle analysis by flow cytometry. Compared to this analysis method, the BioTracker™ Far Red Live Cell Cycle Assay Solution does not require cell fixation or permeabilization, and is permeable in live cells. Use 5 uL of probe solution in 500 uL for each sample. Vial contains enough for 50 tests.IMPORTANT APPLICATION NOTES:*Wash cells thoroughly to remove trypsin. Residual trypsin can confound analysis of flow cytometry populations.*Adjust gates after cells are stained with probe SPECTRAL PROPERTIESExcitation: 405 - 407 nmEmission: 450/50 BPUse violet laser for excitation.，官网链接：https://www.sigmaaldrich.cn/product/mm/sct281 默克 科研、开发、生产。 作为生命科学行业的全球领先供应商，我们致力于为科研、生物技术开发和生产，以及制药药物疗法开发和生产提供各类解决方案和服务。
