T細胞擴增GT-T551 H3無血清培養(yǎng)基

產品英文名稱：GT-T551 H3 Culture medium, 1L Bottle

產品中文名稱：GT-T551 H3無血清培養(yǎng)基

適用：淋巴細胞、DC細胞、NK細胞培養(yǎng)

特別應用：T細胞擴增，與CD3單抗一起活化T細胞

保存：2℃ to 8℃

產品形態(tài)：透明液體

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

GT-T551培養(yǎng)基適合人T淋巴細胞（T細胞）的擴增。培養(yǎng)基添加了人白蛋白（醫(yī)藥級別），重組人胰島素，L-谷氨酰胺和鏈霉素，不含其它蛋白和生長因子。不論是否添加血清，GT-T551都能支持細胞穩(wěn)定生長。

GT-T551培養(yǎng)基支持Anti-CD3/IL-2介導的T細胞刺激活化。用這種方法激活T細胞時，如添加RetroNectin重組人纖維蛋白片段可以增強T細胞的擴增，而且所得T細胞比單獨使用CD3單抗產生更多 naïve T cells（初始T細胞）。

GT-T551 培養(yǎng)基產品特點

日本*無血清培養(yǎng)基，已經加入人血白蛋白組分。

支持淋巴細胞的高密度細胞培養(yǎng)。

在日本多家醫(yī)院用于臨床治療的細胞培養(yǎng)。

配制用水符合國家藥監(jiān)局《人體細胞治療研究和制劑質量控制指導原則》中注射用水標準。

GT-T551 培養(yǎng)液在使用前加入病人0.6%自體血漿，性能可以和許多高價培養(yǎng)液效果相同。

GT-T551 H3 是GT-T551的升級版培養(yǎng)基，采用全新的緩沖系統(tǒng)，可用于無血漿培養(yǎng)，CD3+CD56+比例高。如果培養(yǎng)時添加病人自體血漿，效果更為顯著。

GT-T551培養(yǎng)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.

細胞擴增速度

人PBMCs（外周血單個核細胞）經CD3單抗刺激活化4天后，使用GT-T551培養(yǎng)基擴增培養(yǎng)。相比其他培養(yǎng)基，GT-T551在沒有添加人AB血清的情況下仍然能保持T細胞穩(wěn)定生長。

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.

培養(yǎng)體系：GT-T551培養(yǎng)基，CD3單抗，CultiLife培養(yǎng)袋，添加0.6%的熱滅活血漿。添加RetroNectin重組人纖維蛋白片段后，T細胞擴增大幅上升，并且得到高比例的初始T細胞。

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

GT-T551和CultiLife 培養(yǎng)袋一起使用后，T細胞擴增效率更高。

T細胞擴增方法詳見TAKARA GT-T551說明書。

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.
