Anti-Human TNF-β

Purified Recombinant Human TNF-β (>98%)

This antigen affinity purified polyclonal antibody has been 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 containing 5.0% w/v trehalose with no calcium, magnesium, or preservatives present.

Lyophilized

The lyophilized antigen affinity purified polyclonal antibody can be stored desiccated at -20°C to -70°C for twelve months from date of receipt. The reconstituted antibody can be stored for at least four weeks at 2-8°C. For long-term storage of the reconstituted antibody, aseptically aliquot into working volumes and store at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. No detectable loss of activity was observed after six months.

Neutralization: Measured by its ability to neutralize Lymphotoxin‑ alpha /TNF‑ beta -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 0.01-0.03 µg/mL in the presence of 0.25 ng/mL Recombinant Human Lymphotoxin‑ alpha /TNF‑ beta and 1 µg/mL actinomycin D.

Rabbit Anti-Human Tumor Necrosis Factor-Beta (TNF-β) recognizes Human TNF-β. This antigen affinity purified polyclonal antibody was purified using a proprietary chromatographic technique that includes covalently immobilizing the antigen proteins or peptides to agarose based beads. This purification method enhances specificity, reduces nonspecific binding of extraneous IgG and provides you with the most reliable reagent available for your early discovery research.

Tumor necrosis factor-beta (TNF beta) also known as lymphotoxin alpha (LT alpha), is a multifaceted pro-inflammatory cytokine which may mediate some of the significant changes in cellular homeostasis which accompany the invasion of the mammalian host by viruses, bacteria, and parasites.¹ TNF beta has been implicated in the pathogenesis of several autoimmune diseases and it plays a significant role in the etiopathogenesis of multiple sclerosis (MS).²
