DEF-CS是单个干细胞基因操作的理想选择，和目前市场上的相关产品不同的是，DEF-CS在设计上就是支持单细胞生长的。

DEF-CS 500诱导多能干细胞无血清培养基

英文名称：Cellartis® DEF-CS™ 500 Culture System

中文名称：Cellartis® DEF-CS™ 500人iPS细胞无血清培养系统

特点：成分确定 无血清 无饲养层 *培养基

用途：iPS细胞大规模培养，单细胞培养，转染和Scaffold接种。

保存：基础培养基和包被剂2-8°C，添加剂-20°C

DEF-CS系统是一个强大的培养系统，用于在无饲养层和确定环境下高效扩增人诱导多能干细胞（iPS）。该系统能够实现稳定的生长速率，适合传统iPS细胞培养，细胞批量生产和单细胞培养。用此培养系统生长的细胞保持未分化状态，不会有可检测的背景分化，无需细胞选择。酶法传代的单细胞可用于单细胞相关应用，包括高通量筛选，转染和支架接种（scaffold seeding）。

☆ 成分确定、无血清、无饲养层培养

☆ All-In-One型：培养液+添加剂+包被剂

☆ 细胞单层生长，可进行单细胞传代

☆ 维持未分化状态，无需筛选分化细胞

☆ 单个干细胞基因操作实验的理想选择

产品应用

·放大和大规模生产人类iPS诱导多能干细胞

·人类iPS诱导多能干细胞的单细胞培养

·转染和重编程

·高通量筛选

·组织工程（支架接种）

DEF-CS是单个诱导多能干细胞基因操作的理想选择

Human iPS和Human ES增殖用培养基(DEF-CS Culture System, all-in-one format)

作为一款创新型的产品，Cellartis DEF-CS培养系统使得单细胞干细胞操作成为常规的操作。该产品是专门针对人类诱导多能干细胞（hiPS）和人类胚胎干细胞（hES）研发的高效率增殖用培养基产品体系。该产品系统为all-in-one型，包括了所有组分，客户不需要另外求购组分。该产品是成分确定的培养基产品，而且不需要饲养层。DEF-CS既可以实现单细胞培养，也可以用于传统的iPS培养模式以及大规模干细胞增殖。在使用DEF-CS培养基增殖干细胞时，几乎没有背景分化的问题，这使得细胞筛选不再必需。作为一款创新产品，利用DEF-CS培养干细胞时，可以使用酶消化法（enzymatic passaging）实现需要单细胞操作，这一特点十分有利于高通量细胞鉴别筛选（high-throughput screening）、转染（transfection）、支架接种（scaffold seeding）等。

诱导多能干细胞培养性能

单细胞传代

Human induced pluripotent stem (iPS) cells can be passaged as single cells in the Cellartis DEF-CS Culture System. A single GFP-actin iPS cell was isolated and placed in the well of a culture dish. Twenty-four hours after seeding, morphology was assessed by fluorescence microscopy at 20x (Panel A) and 40x (Panel B) magnification. Sixteen days later, the single GFP-actin iPS cell had proliferated into numerous cells as evidenced by microscopic observation at 4x (Panel C), 10x (Panel D), 20x (Panel E), and 40x (Panel F) magnification.

扩增潜力

Expansion potential of a characterized working bank of human induced pluripotent stem (iPS) cells in the Cellartis DEF-CS Culture System. The Cellartis DEF-CS Culture System can produce 2 x 109 human iPS cells within 4 passages (18–20 days) from frozen cells (2.0–2.5 x 106 cells).

多能干性维持

Human pluripotent stem cells remain undifferentiated when cultured in the Cellartis DEF-CS Culture System. Human iPS cells cultured for 23 passages in the Cellartis DEF-CS Culture System were characterized by Oct-4 staining (A) and nuclear staining (B).
