Cd3 cd28 magnetic dynabeads cts

Manufactured by Thermo Fisher Scientific

The CD3/CD28 magnetic dynabeads (CTS) are laboratory equipment used for the activation and expansion of T cells. They consist of superparamagnetic beads coated with antibodies against the CD3 and CD28 surface receptors on T cells. These beads can be used to stimulate T cell proliferation and differentiation in cell culture applications.

Leukapheresis products from anonymous healthy human donors were purchased from STEMCELL Technologies, Inc. and isolated using an EasySep human T-cell isolation kit (Cat #17951). Isolated CD3+ T cells were activated at 1 × 106 cells/ml in a 1:1 ratio with CD3/CD28 magnetic dynabeads (CTS, Thermo Fisher Scientific), 100 U/ml IL-7 and 10 U/ml IL-15 (R&D Systems) for 48 h in complete XVivo15 medium (Lonza) (5% FBS, 50 μM 2-mercaptoethanol, 10 mM N-acetyl l-cysteine). Following the 48-h activation period, CD3+ T cells were debeaded with an EasySep magnet (STEMCELL Technologies, Inc.) prior to resuspension and electroporation at 0.5–1 × 106 cells/ml in P3 buffer (Lonza). Following electroporations with RNPs and HDR templates, fresh medium and cytokines were added every 2–3 days.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
