High-quality human embryonic stem cell kits for expansion and differentiation into all three germ layers

Cellartis human embryonic stem (ES) cell line kits contain human ES cells that have been ethically derived under feeder-free conditions, then banked and characterized according to the highest industry standards. The human ES cells are adapted to the Cellartis DEF-CS culture system, an easy-to-use, complete culture system for pluripotent cell expansion in a defined, feeder-free environment that maintains high levels of pluripotency. The reproducible nature of the DEF-CS system coupled with the stable high growth rate of these stem cell lines is ideal for small- or large-scale expansion, as well as any major downstream applications.

  • Cells are extensively analyzed for purity, recovery after thawing, absence of mycoplasma and bacteria, expression of stemness markers, absence of differentiation markers, and expected karyotype
  • Cellartis hES cell lines are available from four donors and are supplied from fully characterized cell banks
  • The derivation process follows all applicable laws in Sweden and the EU and is approved by a regional ethical authority

Trypsin mini spin columns for rapid, complete protein digestion

Capturem Trypsin digests proteins completely in less than two minutes at room temperature, allowing for an uninterrupted proteomic analysis workflow. It consists of membrane-immobilized trypsin in a mini spin column format which is based on our novel Capturem technology. Capturem Trypsin offers the following advantages over in-solution trypsin digestion:

  • Digestion of protein samples in less than two minutes instead of overnight
  • More efficient and complete protein digestion
  • Fewer autolyzed trypsin fragments and protein modifications
  • More effective peptide and protein identification in MS analysis

Move beyond traditional immunoprecipitation (IP) and co-immunoprecipitation (Co-IP) workflows

Although IPs and Co-IPs are still frequently used to study protein interactions, the traditional purification methods used for isolation of the antigen-protein complexes can be time-consuming. The Capturem IP & Co-IP Kit combines high-capacity, membrane-based Capturem Protein A columns with optimized lysis, wash, and elution buffers for a complete, easy-to-use solution.

  • Isolates antibody-bound protein complexes in just 15 minutes—from incubation of antibody with sample through elution
  • Reduces the chances of aggregation, loss of activity, and complex disassociation
  • Includes Capturem Protein A columns and optimized IP buffers

CRISPR/Cas9 editing made faster by protein delivery

Guide-it Recombinant Cas9 (Electroporation-Ready) is the newest addition to our line of products for CRISPR/Cas9 gene editing experiments. Delivery of Cas9-sgRNA ribonucleoprotein complexes provides a fast turnaround for gene-editing experiments while minimizing the likelihood of off-target effects compared to vector-based approaches.

  • Works well in hard-to-transfect cell lines
  • Minimizes off-target effects—better than plasmid-based delivery systems 
  • Enables highly efficient editing when combined with our Guide-it Complete sgRNA Screening System
  • Provides a faster turnaround for gene editing experiments

Inducible, lentiviral-mediated CRISPR/Cas9 genome editing

The Lenti-X Tet-On 3G CRISPR/Cas9 System is a complete system for lentiviral-mediated CRISPR/Cas9 genome editing. This system incorporates the Tet-On 3G transactivator protein, which enables users to induce Cas9 expression via the addition of doxycycline.

  • Viral delivery of the Cas9 gene and an sgRNA allows for genome editing in hard-to-transfect mammalian cells
  • Lenti-X Packaging Single Shots make generating high-titer lentivirus extremely simple
  • Tightest possible control of Cas9 expression allows you to minimize the likelihood of toxicity and off-target effects associated with persistent Cas9 expression in cell culture

New Xeno-Free and GMP-Grade Stem Cell Media Products to Accelerate Discovery

Moving human pluripotent cell-based therapies from the lab to the clinic involves jumping over key hurdles in the process, and our Cellartis brand xeno-free media products are designed with these challenges in mind. Stemming from more than 15 years of expertise in pluripotent cell generation and differentiation, our new additions to the xeno-free media product family aim to maximize the potential of your cell therapy and ultimately influence human health.

  • Our original xeno-free medium promotes robust 2D monolayer expansion and is suitable for preclinical and research applications.
  • Our NEW xeno-free 3D spheroid culture medium is optimized for scale-up of iPSCs as 3D spheroids for downstream directed differentiation—5 x 109 cells in a 1 liter bioreactor within 3–4 passages.
  • Our NEW xeno-free GMP-grade basal medium is manufactured with clinical-quality materials and traceable production processes, and is ideal for small- or large-scale production of pluripotent cells for downstream use in clinical research settings.

Efficient T-Cell Culture and Expansion Medium

Promoting robust T-cell expansion is an important prerequisite for basic and preclinical studies, including adoptive cell therapy studies. GT-T551 Culture medium, 1L Bottle is ideally suited for expansion of T cells, and is recommended in our protocol for anti-CD3/IL-2 T-cell activation in conjunction with RetroNectin. This protocol results in an expanded cell population that shows a higher proportion of naïve T cells than anti-CD3 antibody stimulation alone. This T cell medium is:

  • 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
