Emerging Targets for Cancer Immunotherapy Research

星期二, 四月 18, 2017 - 09:27
Emerging Targets for Cancer Immunotherapy Research

The most successful strategies for cancer immunotherapy have focused on targeting the T cell co-stimulatory and co-inhibitory molecules that regulate T cell activation. Monoclonal antibodies directed against the T cell co-inhibitory receptors, CTLA-4 and PD-1 have been shown to have potent anti-tumor effects, suggesting that other immune checkpoint regulators may also serve as immunotherapeutic targets. CTLA-4 and PD-1 are members of the CD28 family and they each bind...

Good Manufacturing Practice (GMP) for Cell Therapy Manufacturing: What does this mean?

星期五, 四月 14, 2017 - 14:29
gmp cytokines and growth factor use in cell therapy process

 

Several suppliers, including R&D Systems, offer growth factors and cytokines made specifically for culturing cells that will be used for cell therapy. They are only to be used during the cell culture process and residual protein is washed away before the cells actually come into contact with a patient. These reagents are commonly referred to as GMP (Good Manufacturing Practice), a term that has traditionally been reserved for materials made with oversite from federal regulatory authorities like the FDA. Despite the...

Paul Maye, Ph.D., Assistant Professor, University of Connecticut Health Center

Bone marrow stromal cells have been one of the more intensively studied adult stem cell types over the past 50 years. There is great interest within regenerative medicine and wound healing for this adult stem cell type because of its complex biological properties including its ability to support a hematopoietic environment, possess anti-inflammatory qualities, and differentiate down multiple lineages. This webinar discusses research that helps us understand their origin, identity, and biological complexity. This includes:

  • Ways to isolate and culture stromal cells.
  • in vitro assays of multipotency.
  • Assays to quantify stromal cells.
  • Benefits of murine transgenic animal models to study stromal cells and...

Luminex HP Assays 101 – Sensitivity Matters

星期一, 三月 13, 2017 - 13:49
cartoon phd lab data

Sensitivity is critical for immunoassays so that analytes present at low levels can be accurately measured. Without proper sensitivity, low abundance analytes can be missed completely even if they are present in a sample. Additionally, it can be difficult to compare healthy vs. disease samples since analytes that are overexpressed in disease states are often present at very low levels in healthy individuals. Our Luminex High Performance Assays provide superior sensitivity, and here's how:

Proven Assay Development Expertise

R&D Systems has over 25 years of experience designing, testing, and optimizing immunoassays to ensure the highest level of performance in analyte quantification. Luminex High Performance assays are driven by the same expertise...

Why Use Standardized Kits When Differentiating Pluripotent Stem Cells

星期四, 二月 23, 2017 - 13:35

Standardized pluripotent stem cell differentiation kits, such as the StemXVivo® Differentiation Kits from R&D Systems, offer a number of benefits over both home-brew protocols or the direct purchase of pre-differentiated iPS cells. This post provides a brief discussion of those benefits:

Consistent Method for Assessing Pluripotency – Researchers creating iPS cell lines must verify the pluripotency of their newly generated cells. The teratoma assay and the embryoid body assay are the historical standard for validation. However, they are time consuming and inconsistent. Differentiation kits are ideal for applying a fast and standardized method to pluripotency validation because they...

Xeno-free, Serum-free, What’s for me? - Mesenchymal Stem Cell Media

星期三, 二月 1, 2017 - 07:46

Mesenchymal stem cells (MSC) hold significant promise for tissue engineering and regenerative medicine. While the use of MSCs for both translational and basic research requires their efficient expansion, the desired media formulations for growing MSCs can vary by application. Specific formulations of MSC media now exist to address these various applications, including serum-containing, serum-free, xeno-free, and GMP-grade media. For many researchers, deciphering which variant of MSC media best suits their needs can be a daunting prospect. This post is meant to help clarify MSC media nomenclature and provide a quick reference for understanding the various media options and when to use them in your research.

星期五, 十二月 16, 2016 - 08:50

Joy Aho, PhD, Manager of Stem Cells Research and Development Bio-Techne
Ernesto Resnik, PhD, Manager of Antibody Research and Development Bio-Techne

In this peer-reviewed video publication, featured in the Journal of Visualized Experiments (JoVE), Bio-Techne scientists provide data supporting new methods for reliably inducing epithelial to mesenchymal transition (EMT) in vitro. EMT is essential for proper morphogenesis during development. Misregulation of EMT is attributed to fibrosis and the progression of carcinomas metastasis. Creating reliable cell culture models for EMT induction and analysis is key for gaining insights into the field of wound healing and cancer metastasis. In this video, we demonstrate a straightforward method for the induction of EMT in a variety of cell types,...
