TNF-alpha/TNFSF2 Protein, Mouse (156a.a, His)

Cat. No.: HY-P7090B
Handling Instructions

Tumour Necrosis Factor alpha (TNF alpha) is a potent pro-inflammatory cytokine. TNF alpha binds to its receptors, mainly TNFR1 and TNFR2, and then transmits molecular signals for biological functions such as inflammation and cell death. TNF alpha stimulates NF-κB pathway via TNFR2 promotes cancer growth, invasion, and metastasis. Anti-TNF-α MAb significantly suppresses the tumor development in colitis-associated cancer (CAC) mouse. TNF alpha as a proneurogenic factor activates the SAPK/JNK Pathway and can facilitate neuronal replacement and brain repair in response to brain injury. TNF-alpha/TNFSF2 Protein, Mouse (156a.a, His) is a recombinant protein with a N-Terminal His label, It consists of 156 amino acids (L80-L235) and is produced in E. coli.

Description

Tumour Necrosis Factor alpha (TNF alpha) is a potent pro-inflammatory cytokine[1]. TNF alpha binds to its receptors, mainly TNFR1 and TNFR2, and then transmits molecular signals for biological functions such as inflammation and cell death[2]. TNF alpha stimulates NF-κB pathway via TNFR2 promotes cancer growth, invasion, and metastasis. Anti-TNF-α MAb significantly suppresses the tumor development in colitis-associated cancer (CAC) mouse[3]. TNF alpha as a proneurogenic factor activates the SAPK/JNK Pathway and can facilitate neuronal replacement and brain repair in response to brain injury[4]. TNF-alpha/TNFSF2 Protein, Mouse (156a.a, His) is a recombinant protein with a N-Terminal His label, It consists of 156 amino acids (L80-L235) and is produced in E. coli.

Background

TNF alpha is produced by various types of cells including macrophages, monocytes, neutrophils, T cells, and NK-cells[2].
The amino acid sequence of human TNF alpha protein has low homology between mouse, rat, bovine, cynomolgus TNF alpha protein. While, human TNF alpha shares 94.85% aa sequence identity with cynomolgus TNF alpha protein, mouse TNF alpha shares 94.47% aa sequence identity with rat TNF alpha protein.
TNF alpha exists in two forms; a type II transmembrane protein (tmTNF-α) and a mature soluble protein (sTNF-α). TNF-α binds to its receptors, mainly TNFR1 and TNFR2, and then transmits molecular signals for biological functions such as inflammation and cell death. Both sTNF-α and tmTNF-α activate TNFR1, and process a death domain (DD) that interacts with the TNFR1-associated death domain (TRADD) adaptor protein. The TNFR2 signaling pathway is mainly activated by tmTNF-α. TNFR1 signaling tends to be pro-inflammatory and apoptotic. TNFR2 results in NF-κB and MAPKs and AKT activation, TNFR2 activation is associated with homeostatic bioactivities such as tissue regeneration, cell proliferation, and cell survival, as well as host defense and inflammation[1].
TNF-alpha is critical for normal immune response, abnormal secretion TNF alpha activates synovial fibroblasts, keratinocytes, osteoclasts, induces rheumatoid arthritis, inflammatory bowel disease, psoriatic arthritis (PsA), and noninfectious uveitis (NIU)[3]. TNF alpha positively regulates endogenous TNF-α expression levels independently of Pgp efflux activity, induces IHF cells proliferation[4]. TNF alpha in tissues may promote cancer growth, invasion, and metastasis. Besides, TNF alpha stimulates NF-κB pathway via TNFR2 and anti-TNF-α MAb significantly suppresses the tumor development in colitis-associated cancer (CAC) mouse[5]. TNF alpha as a proneurogenic factor activates the SAPK/JNK pathway and can facilitate neuronal replacement and brain repair in response to brain injury[6].

In Vitro

TNF alpha (mouse) (0, 2.5, 5, 10, 20, 40 ng/ml; 5 min) stimulates NF-κB Pathway and upregulates the phosphorylation of p65 and IκBα in CT26 cells in a dose-dependent manner[5].
TNF alpha (mouse) (1, 10 ng/mL; 7 days) induces neuronal differentiation in SVZ cells via TNFR1 activation[6].
TNF alpha (mouse) (1, 10; 100 ng/mL; 48 h) induces cell proliferation at 1 ng/mL and at high concentrations (10 and 100 ng/ml) TNF-α induces cell apoptosis in SVZ cells[6].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
