脂质组学分析

提供多样化的脂质定量分析服务,涵盖了无与伦比生物脂质组的范围,包含了超过10,000种的脂质及其衍生物。

脂质组学的目标在于建立整个细胞或组织内的所有脂质的综合脂质图谱,已成为联系脂质生物学、技术和医学的一门独立学科。近期在脂质组学研究领域的发展风潮主要归功于分析技术的进步,特别是用于定性和定量细胞脂质组中一系列众多脂质种类的新型质谱和色谱仪器的发展(Lam SM et al., 2013 and 2017)。在中科脂典,我们提供多样化的脂质定量分析服务,涵盖了无与伦比生物脂质组的范围,包含了超过10,000种的脂质及其衍生物。
       对于只含有痕量脂质的人类泪液的脂质组学描述的署名工作中,我们的脂质组学技术的能力得到了证实。我们关于人类泪液的脂质组学的研究在Journal of Lipid Research上发表了一系列的论文(Lam SM et al., 2014, 2014, 2014) 并被ASBMB TODAY推荐。此外,我们对血清、血浆、尿液、牛奶等各种生物体液以及不同类型的生物组织和器官(Shui G et al., 2012; Wang W et al., 2012; Chua EC et al., 2013; Nguyen LN et al., 2014)脂质组分析有着丰富的经验。更多的详细信息,请参阅我们的脂质组服务介绍视频(视频链接)。凭借我们在脂质研究领域的丰富经验,我们还为感兴趣的客户提供有关选择脂质分析覆盖率选择的咨询服务以便最好地满足客户需求。
