Application
Ficoll® PM 400与泛影酸(Paque)一起使用，产生Ficoll-Paque，是一种用于分离细胞和细胞器的密度混合物，特别是血液来源的淋巴细胞和单核细胞。它可用于组织工程和大分子构象研究，用于大分子拥挤（MMC）系统和配置的开发、评估和使用。Ficoll PM-400可应用于细胞冷冻-干燥研究。
用于细胞分离和细胞器分离。
Features and Benefits
由于高分子量和低含量的透析性材料，Ficoll对细胞膜的渗透性比蔗糖低得多。 因此，细胞在梯度Ficoll下的聚集密度要低于梯度蔗糖。Ficoll由于其低膜渗透性和低渗透压，通常能较好地保存细胞功能和形态。
General description
Ficoll 400是由蔗糖和环氧氯丙烷共聚而成的一种高度分支化的聚合物。 Ficoll 400是完全非离子性的。 由于其含有丰富的羟基，Ficoll 400具有很强的亲水性和水溶性。 Ficoll 400最常见的应用是作为密度梯度介质，用于真核细胞、细胞器和细菌细胞的分离和分离。密度范围可达1.2 g/ml。 它还被用于一系列其他应用中。
Preparation Note
水的浓度可达到50% (w/v)。 Ficoll应在持续搅拌下缓慢加入。
Sigma测试Ficoll 400的溶解度，其1g溶于10ml去离子水中时呈透明到微模糊，无色到淡黄色的溶液。 Ficoll在碱性和中性溶液中稳定。当pH值低于3时，它会迅速水解，尤其是在高温下。 Ficoll可在110oC的中性pH下高压灭菌30分钟。 应避免使用强氧化性和还原性试剂。

Seronegative brucellosis is occasionally encountered in clinical practice especially in localized disease where diagnosis is reached mainly through positive blood culture. Cellular immune responses are pivotal for protection against intracellular bacteria such as Brucella. This study was performed to evaluate
