PromoCell Mononuclear Cells (MNC) represent the lymphocyte and monocyte fraction isolated from umbilical cord blood or peripheral blood. They are prepared by optimized low-density gradient centrifugation, which effectively reduces the granulocyte content. Red blood cells are gently but thoroughly depleted by proprietary techniques instead of osmotic lysis. This results in ultra-pure mononuclear cells with superior viability and unchanged biological function. In addition, the cells do not clump after thawing, allowing for easy handling and reproducible results.
The MNC can be used directly for experiments or as a starting material for the isolation of several cell types, e.g., hematopoietic and endothelial progenitors, monocytes, and lymphocyte subpopulations.
NEW: Our hMNC are now also available from HLA-typed donors.
Available formats:
- Cryopreserved: Cryogenic vial containing 25.000.000 viable cells.
- Cell pellet: 1 million cells dissolved in 200µl RNAlater© for subsequent RNA, DNA or protein analysis. Cell pellets cannot be revived.

抗原与其所诱导产生的抗体或致敏淋巴细胞特异性结合的能力。抗原性的强弱与抗原分子的大小、化学成分、抗原决定簇的结构、抗原与被免疫动物亲缘关系的远近等有密切关系。通常认为抗原的分子量愈大、化学组成愈复杂、立体结构愈完整以及与被免疫动物的亲缘关系愈远,则抗原性愈强。抗原的物理状态也对抗原性发生影响,例如蛋白质,聚合状态的比单体的抗原性强,一般球形分子的比纤维形分子的抗原性强。抗原加入佐剂改变物理状态后,抗原性也得到增强。例如,分子量高达10万的明胶由于缺乏苯环氨基酸,稳定性较差,在进入机体后容易被酶降解成低分子物质,如果加入少量酪氨酸(苯环氨基酸),就能增强其抗原性。

抗原性介绍:流感病毒按抗原性
1.抗原性是指抗原与其所诱导产生的抗体或致敏淋巴细胞特异性结合的能力。抗原性的强弱与抗原分子的大小、化学成分、抗原决定簇的结构、抗原与被免疫动物亲缘关系的远近等有密切关系。通常认为抗原的分子量愈大、化学组成愈复杂、立体结构愈完整以及与被免疫动物的亲缘关系愈远,则抗原性愈强。
2.免疫原性是指能够刺激机体形成特异抗体或致敏淋巴细胞的能力。即指抗原能刺激特定的免疫细胞,使免疫细胞活化、增殖、分化,最终产生免疫效应物质抗体和致敏淋巴细胞的特性。也指抗原刺激机体后,机体免疫系统能形成抗体或致敏T淋巴细胞的特异性免疫反应。
