Biological Activity

Description

TNF-alpha/TNFSF2 Protein, Mouse (His) is recombinant mouse tumor necrosis factor alpha (TNF-α) with his tag.TNF-alpha/TNFSF2 Protein, a major mediator of inflammation, is involved in a number of infectious and parasitic diseases.

Background

Tumor necrosis factor-α (TNF-α) is a pleiotropic cytokine produced by a wide variety of cell types of mostly hematopoietic, but also of nonhematopoietic, origin. TNFα is instrumental in the immune elimination of various infectious agents such as Candida albicans, Listeria monocytogenes, or mycobacteria and exerts potent proinflammatory effects, e.g. by inducing the expression of adhesion molecules such as VCAM-1, intercellular adhesion molecule 1 (ICAM-1), or E-selectin on endothelial cells and other cell types[1][2].

Verified Bioactivity

The ED50 is ≤0.06 ng/mL as measured by L-929 mouse fibrosarcoma cells, corresponding to a specific activity of ≥1.7 × 107 units/mg.

MCE Validation Data

  • Purity - SDS-PAGE

    Purity - SDS-PAGE

    ≥ 95%, as determined by reducing SDS-PAGE.

  • Bioactivity - Cell-Based Assay

    Bioactivity - Cell-Based Assay

    The ED50 is <0.05 ng/mL as measured by L-929 mouse fibrosarcoma cells, corresponding to a specific activity of >2 × 107 units/mg.

Product Properties

Appearance

Lyophilized powder.

Formulation

1.Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.
2.Lyophilized from a 0.22 μm filtered solution of 50 mM Tris-HCl, 300 mM NaCl, pH 7.4, 5% trehalose, 5% mannitol and 0.01% Tween 80.
Please refer to the lot-specific COA for specific buffer information.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

Endotoxin Level

<1.0 EU/μg, determined by LAL method.

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping

Room temperature in continental US; may vary elsewhere.
