Features:

LipidFlex T Cell Kit is a lipid nanoparticle (LNP) reagent mix. It is a highly efficient lipid formulation used to synthesize mRNA LNP for optimized gene delivery to primary human T cells. Using the NanoGenerator Flex-S system and CHIP-MIX-4 cartridge, customers can conveniently prepare potent mRNA LNP with high efficiency.

With PreciGenomes LipidFlex T cell kit, the mean fluorescence intensity increased at least 200 fold (blue) compared to the negative control (red).

Protein expression level is dependent on the mRNA LNP dose. This can be seen as the mean fluorescence intensity increases with mRNA dose in T cells.

Over 90% of the cells are alive after the treatment which corresponds to the negative control in human T-cells and Jurkat cells. 

脂质纳米颗粒与合成:

脂质纳米粒 (LNP) 或固体脂质纳米粒 (SLNs, sLNPs) 是由脂质组成的纳米粒子,具有固体 脂质 核心矩阵能够 溶解 亲脂性的 分子。通常它们是球形的,平均直径在 10 到 1000 纳米之间。

脂质纳米颗粒已成为整个制药行业的一种有前途的载体,可以提供多种治疗方法。 它们是一种新型药物给药系统和制剂。 LNP 在 2020 年底变得更加广为人知,因为一些使用 RNA 疫苗技术的 COVID-19 疫苗用聚乙二醇化脂质纳米粒子作为其运载工具来包裹脆弱的 mRNA 链。

脂质体是 LNP 的早期版本,是一种多功能的纳米药物递送平台。许多脂质体药物已被批准并应用于医疗实践。脂质体是具有至少一个脂质双层的球形囊泡。该脂质体可用作营养素和药物给药的载体。 
脂质体是复合结构,由磷脂组成,尤其是磷脂酰胆碱。它可能含有少量其他分子。尽管脂质体的尺寸范围可以从低微米到几十微米不等,但单层脂质体(如下图所示)通常在具有各种靶向配体的较低尺寸范围内。配体附着在它们的表面上,允许它们在病理区域进行表面附着和积累以治疗疾病。
