Lymphotoxin-α (LT-α), also known as tumor necrosis factor-beta (TNF-β), is a potent lymphoid factor that exerts cytotoxic effects on a wide range of tumor cells and certain other target cells. LT-α possesses a signal peptide sequence and is a secreted protein; however, LT-α is also present on the surface of activated T, B and LAK cells as a complex with LT-β. Bioactive LT-α exists as a homotrimer.Product Details
- Antibody Type
- Host Species
- E. coli expressed, recombinant human LT-α.
- Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
- The antibody was purified by affinity chromatography, and conjugated with biotin under optimal conditions. The solution is free of unconjugated biotin.
- 0.5 mg/ml
- Storage & Handling
- The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze.
ELISA Detection - Quality tested
ELISPOT Detection, ICFC - Reported in the literature
- Recommended Usage
Each lot of this antibody is quality control tested by ELISA assay. For ELISA detection applications, a concentration range of 0.25-1.0 µg/ml is recommended. For flow cytometric staining, the suggested use of this reagent is ≤ 0.25 µg per 106 cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
ELISA or ELISPOT Detection1,2: The biotinylated 359-81-11 antibody is useful as a detection antibody for a sandwich ELISA or ELISPOT assay, when used in conjunction with purified 359-238-8 antibody (Cat. No. 503002/503004) as the capture antibody.
Flow Cytometry3: The fluorochrome-labeled 359-81-11 antibody is useful for intracellular immunofluorescent staining and flow cytometric analysis to identify LT-α -producing cells within mixed cell populations. View intracellular cytokine staining protocol.
Neutralization1,2: The 359-81-11 antibody can neutralize the bioactivity of natural or recombinant LT-α. The LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm filtered) is recommended for neutralization of human LT-α bioactivity (Cat. No. 503108).
Additional reported applications (for the relevant formats) include: immunohistochemical staining of paraformaldehyde-fixed, saponin-treated frozen tissue sections, and immunocytochemistry.
