Product Details
Alternative Name: | Apo-2L, TNFSF 10, CD253 |
|
Source: | Produced in E. coli. The extracellular domain of human TRAIL (aa 95-281) is fused at the N-terminus to a His-tag and a linker peptide. |
|
UniProt ID: | P50591 |
|
Formulation: | Liquid. In 20mM HEPES, pH 7.4, containing 150mM sodium chloride, 0.005% Tween 20, 1% sucrose, 1mM DTT. |
|
Purity: | ≥98% (SDS-PAGE) |
|
Purity Detail: | Affinity purified. |
|
Endotoxin Content: | <10EU/µg protein (LAL test; Bio Whittaker). |
|
Species reactivity: | Human, Mouse
|
|
Specificity: | Binds to human and mouse TRAIL receptors and osteoprotegerin (OPG). |
|
Biological Activity: | Induces apoptosis in a concentration range of 10-100ng/ml.
Note: This protein does not require a cross-linking enhancer for its potent biological activity. For cell lines that require extensive cross-linking of the TRAIL-Rs for killing (e.g. Jurkat) use SUPERKILLERTRAIL® (Prod. No. ALX-201-115). |
|
Specific Activity: | ED50: 20ng/ml (BJAB cells) |
|
Reconstitution: | For a special storage and dilution buffer see KillerTRAIL™ Storage and Dilution Buffer (Prod. No. ALX-505-005). |
|
Shipping: | Dry Ice |
|
Long Term Storage: | -80°C |
|
Handling: | Avoid freeze/thaw cycles. After opening, prepare aliquots and store at -80°C. |
|
Regulatory Status: | RUO - Research Use Only |

Figure: Apoptosis of TRAIL-sensitive cells. Concentration dependence of apoptosis induction in Jurkat and BJAB cells by
KillerTRAIL™, Soluble (human) (recombinant) (Prod. No.
ALX-201-073) reveals high activity even at concentrations of 10-100ng/ml.
Method: 5x10
4 human Jurkat (JK) or BJAB cells were cultured in 100µl RPMI 1640 medium containing 10% fetal calf serum for 16 hours at 37°C in a 96-well plate in the presence of the indicated concentrations of
KillerTRAIL™. Concentrations of
KillerTRAIL™ required to induce apoptosis may vary depending on the cell type studied. Cell death was quantified by forward/sideward scatter (FSC/SSC) combined with propidium iodide (PI) staining analysed by flow cytometry."

Figure: Specificity of
KillerTRAIL™-induced apoptosis. Concentration dependent blocking of apoptosis induction of BJAB cells using MAb to TRAIL (human) (2E5) (Prod. No.
ALX-804-296) reveals specificity of
KillerTRAIL™-mediated killing.
Method: Human BJAB cells were treated with
KillerTRAIL™, Soluble (human) (recombinant) (at 300ng/ml) in the presence or absence of the indicated concentration of the MAb to TRAIL (human) (2E5) or a control IgG1 mouse monoclonal antibody. After 16 hours apoptosis was evaluated by forward/sideward scatter (FSC/SSC) combined with propidium iodide (PI) stain analysed by flow cytometry."
