Tumor Necrosis Factor alpha (TNF-alpha) is a 17.3kD multi-functional pro-inflammatory cytokine primarily secreted by macrophages, but also produced by T and B lymphocytes, activated monocytes and fibroblasts.
TNF-alpha exists in both a transmembrane and mature soluble form and has many biological properties, including activation of transcription factor NF-KappaB, the induction of apoptosis in various tumor cell lines and the stimulation of cell differentiation and proliferation under certain conditions.
Studies have revealed a role for TNF-alpha in inflammation, septic shock, autoimmune disease and rheumatoid arthritis.
Applications: Suitable for use in neutralization, ELISA, and Western Blot.
Other applications have not been tested.
Recommended Dilution:Neutralization: 0.012-0.014ug/ml required to yield one-half maximal inhibition [ND50] of hTNF-a (0.25ng/ml).
ELISA: 0.2-0.4 ug/ml (using 100ul/well antibody solution) Used in conjunction with compatible secondary reagents, allows the detection of at least 0.2ng/well of recombinant hTNF-a.
Western Blot: 0.1-0.2ug/ml.
Used in conjunction with compatible secondary reagents the detection limit for recombinant hTNF-a is 1.5-3.0ng/lane, under either reducing or non-reducing conditions
Optimal dilutions to be determined by the researcher.
Storage and Stability:May be stored at 4°C before opening.
DO NOT FREEZE! Stable at 4°C as an undiluted liquid.
Dilute only prior to immediate use.
Stable for 12 months after receipt.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Further dilutions can be made in assay buffer.
Freezing alkaline phosphatase conjugates will result in a substantial loss of activity.
Note: Applications are based on unconjugated antibody.
