Recombinant trail

Manufactured by Enzo Life Sciences

Recombinant TRAIL is a protein produced using recombinant DNA technology. It functions as a ligand that can bind to death receptors on the cell surface, potentially inducing programmed cell death.

Apoptosis and Necrosis Quantification

Cells were stimulated with the indicated genotoxic and proapoptotic agents, including bleomycin (Medac), hydrogen peroxide, thapsigargin, tunicamycin, brefeldin A (all from Sigma), as well as recombinant TRAIL and FasL (both from Enzo Life Sciences). After cell harvest using trypsin for differentiated cells and accutase (Millipore) for iPSCs, supernatants containing dead cells and the detached cells were combined. Subsequently, cells were stained with FITC-annexin-V and PI following the instructions of the manufacturer (BD Biosciences) and analyzed by flow cytometry. Cells with positive annexin-V but negative PI staining were considered apoptotic, whereas double-positive cells were considered necrotic.

High-Throughput TRAIL Cytotoxicity Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
H460-M cells were dispensed in two sets of 1536-well plates (Greiner
Bio-One) at 1000 cells/well. After overnight incubation, compounds were added at
multiple doses beginning at 46 μmol/L and diluted 3-fold with DMSO.
After 48 hours, each set of plates received 1 μL of PBS or recombinant
TRAIL (30 ng/mL final concentration, Enzo Life Sciences). Cell viability was
assessed at four hours post-TRAIL addition (PBS for vehicle set) using
CellTiter-Glo reagent (Promega) and luminescence (RLU) was quantified using a
ViewLux (PerkinElmer). A more detailed description of the qHTS is provided as

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.
