T细胞扩增GT-T551 H3无血清培养基

产品英文名称：GT-T551 H3 Culture medium, 1L Bottle

产品中文名称：GT-T551 H3无血清培养基

适用：淋巴细胞、DC细胞、NK细胞培养

特别应用：T细胞扩增，与CD3单抗一起活化T细胞

保存：2℃ to 8℃

产品形态：透明液体

组份：GT-T551 Culture medium, 1L Bottle  1,000 mL

GT-T551培养基适合人T淋巴细胞（T细胞）的扩增。培养基添加了人白蛋白（医药级别），重组人胰岛素，L-谷氨酰胺和链霉素，不含其它蛋白和生长因子。不论是否添加血清，GT-T551都能支持细胞稳定生长。

GT-T551培养基支持Anti-CD3/IL-2介导的T细胞刺激活化。用这种方法激活T细胞时，如添加RetroNectin重组人纤维蛋白片段可以增强T细胞的扩增，而且所得T细胞比单独使用CD3单抗产生更多 naïve T cells（初始T细胞）。

GT-T551 培养基产品特点

日本*无血清培养基，已经加入人血白蛋白组分。

支持淋巴细胞的高密度细胞培养。

在日本多家医院用于临床治疗的细胞培养。

配制用水符合国家药监局《人体细胞治疗研究和制剂质量控制指导原则》中注射用水标准。

GT-T551 培养液在使用前加入病人0.6%自体血浆，性能可以和许多高价培养液效果相同。

GT-T551 H3 是GT-T551的升级版培养基，采用全新的缓冲系统，可用于无血浆培养，CD3+CD56+比例高。如果培养时添加病人自体血浆，效果更为显著。

GT-T551培养基性能

Human PBMCs were cultured for 4 days with anti-CD3 stimulation and further cultured for 10 days with GT-T551 culture medium or competitors’ media products. GT-T551 showed stable expansion of T cells even without the addition of human serum.

细胞扩增速度

人PBMCs（外周血单个核细胞）经CD3单抗刺激活化4天后，使用GT-T551培养基扩增培养。相比其他培养基，GT-T551在没有添加人AB血清的情况下仍然能保持T细胞稳定生长。

PBMCs and autologous plasma were prepared using 50 ml of blood from two healthy volunteers on the basis of informed consent. The effect of RetroNectin (RN) co-stimulation on T-cell expansion was tested using a culture system consisting of GT-T551 Culture medium, IL-2, anti-CD3 mAb, and CultiLife Culture bags, with or without RN. Heat-inactivated plasma at a final concentration of 0.6% was added to the GT-T551 Culture medium at Day 0 and Day 4. RN co-stimulation resulted in a dramatic increase in T-cell expansion and the population contained a high proportion of naïve T cells.

培养体系：GT-T551培养基，CD3单抗，CultiLife培养袋，添加0.6%的热灭活血浆。添加RetroNectin重组人纤维蛋白片段后，T细胞扩增大幅上升，并且得到高比例的初始T细胞。

GT-T551 is effective at expanding T lymphocytes in combination with CultiLife culture bags, as seen here.

GT-T551和CultiLife 培养袋一起使用后，T细胞扩增效率更高。

T细胞扩增方法详见TAKARA GT-T551说明书。

GT-T551 is a culture medium ideally suited for expansion of human T lymphocytes (T cells). It is supplemented with human albumin (pharmaceutical grade), recombinant human insulin, L-glutamine, and streptomycin; no additional proteins or growth factors are added. The medium can support stable growth in the presence or absence of serum.

Anti-CD3/IL-2 T-cell activation can also be performed in this medium (Wang et al. 2013; Ai et al. 2014; Dodo et al. 2014). When using this activation method, the additional presence of RetroNectin enhances the proliferation of T cells (Yu et al. 2008; Ishikawa et al. 2014; Hosoi et al. 2014; Sakamoto et al. 2015; Li et al. 2015) and results in an expanded cell population that shows a higher proportion of naïve T cells than anti-CD3 antibody stimulation alone (Hosoi et al. 2014).

Features

Used for extended culture or expansion of T cells

Supplemented with human serum albumin, human insulin, L-glutamine, and streptomycin

Endotoxin tested (endotoxin <0.3 EU/ml)

Compatible with CultiLife Culture Bags for large-scale expansion of T cells

Anti-CD3/IL-2 T-cell activation in the presence of RetroNectin enhances proliferation and leads to a higher proportion of naïve T cells. For more information, the user manual can be found under the Documents tab.

The method of T-cell expansion by RetroNectin stimulation requires a license from Takara Bio Inc. for uses other than research.
