Preparing a Brain-Mimetic 3D Matrix for Culturing Human Pluripotent Stem Cells
This is a protocol for culturing human pluripotent stem cells (hPSCs) using a 3D matrix. It provides instructions for preparing a brain-mimetic 3D scaffold that can support neuronal growth and for culturing hPSCs. This injectable scaffold can be potentially employed in the field of regenerative medi... More

Radiolabelling Nucleic Acids with [γ-32P] ATP for Analytical Assays
Nucleic acids are readily modified with tags that enable detection, purification, or tracking their interactions with other molecules. One of the standard labels used to generate nucleic acid probes includes radioactive phosphates because they allow for sensitive and rapid detection. This protocol d... More

Evaluate Cell Therapy Product Purity with Aura CL
The CAR-T development workflow is a multi-step process that includes transfection of T cells with a viral vector to express a chimeric antigen and activation/expansion of the CAR-T using a molecule like a Dynabead conjugated to CD3/CD28. Each of these steps is a potential source of contamination tha... More
