Recognizes human Lymphotoxin alpha chains in alpha 2 beta 1 or alpha 1 beta 2 trimers and also human TNF-beta. In direct ELISAs, less than 10% cross-reactivity with recombinant human (rh) APRIL, rhBAFF, rhEDA-A2, rhFas Ligand, rhLIGHT, rhGITR Ligand, rhOX40 Ligand, recombinant mouse RANKL, rhTNF-alpha, rhTRAIL, rhTRANCE, rhTWEAK, or rhVEGI is observed.
Monoclonal Mouse IgG1 Clone # 135125
Protein A or G purified from hybridoma culture supernatant
S. frugiperda insect ovarian cell line Sf 21-derived recombinant human Lymphotoxin alpha / beta
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize Lymphotoxin alpha 2/ beta 1-induced cytotoxicity in the L‑929 mouse fibroblast cell line. Matthews, N. and M. L. Neale (1987) in Lymphokines and Interferons, A Practical Approach. Clemens, M. J. et al. (eds): IRL Press. 221. The Neutralization Dose (ND50) is typically 0.15-0.9 µg/mL in the presence of 10 ng/mL Recombinant Human Lymphotoxin alpha 2/ beta 1 and 1 µg/mL actinomycin D.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Cytotoxicity Induced by Lymphotoxin alpha 2/ beta 1 and Neutralization by Human Lymphotoxin Antibody.
Recombinant Human Lymphotoxin alpha 2/ beta 1 (Catalog # 679-TX) induces cytotoxicity in the the L‑929 mouse fibroblast cell line in a dose-dependent manner (orange line), as measured by Resazurin. Cytotoxicity elicited by Recombinant Human Lymphotoxin alpha 2/ beta 1 is neutralized (green line) by increasing concentrations of Mouse Anti-Human Lymphotoxin Monoclonal Antibody (Catalog # MAB1370). The ND50 is typically 0.15‑0.9 µg/mL in the presence of the metabolic inhibitor actinomycin D (1 µg/mL).

Lymphotoxin alpha, also known as tumor necrosis factor (TNF) beta, and Lymphotoxin beta are members of the TNF superfamily and have been designated TNFSF1 and TNFSF3, respectively. Secreted Lymphotoxin alpha forms a homotrimer (TNF-beta) and heterotrimeric complexes with the type II membrane protein, Lymphotoxin beta (either alpha 2 beta 1 or alpha 1 beta 2 timers). These trimers serve as ligands for Lymphotoxin beta receptor, TNF RI and TNF RII and play a role in the development and maturation of the immune system.
