Ferret TNF-alpha / TNFA ELISA Pair Set

DatasheetReviewsRelated ProductsProtocols
Ferret TNF Materials provided
Capture Ab:0.5 mg/mL of rabbit anti-ferTNFα monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 2 μg/mL in PBS before coating.
Detection Ab:0.2 mg/mL mouse anti-ferTNFα monoclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % HRP-Protector, pH 7.4, store at 4℃). Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.
Standard:Each vial contains 70 ng of recombinant ferTNFα. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A six-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 5 ng/mL is recommended.
Ferret TNF Sensitivity
The minimum detectable dose of Ferret TNF-alpha / TNFA was determined to be approximately 156.25 pg/mL. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
Ferret TNF Principle of the product
The Ferret TNF-alpha / TNFA ELISA Pair Set is for the quantitative determination of Ferret TNF-alpha / TNFA.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for TNF-alpha / TNFA coated on a 96-well plate. Standards and samples are added to the wells, and any TNF-alpha / TNFA present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated mouse anti-TNF-alpha / TNFA monoclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of TNF-alpha / TNFA present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
Ferret TNF Storage
Capture Antibody: Aliquot and store at -20℃ to -80℃ for up to 6 months from date of receipt. Avoid repeated freeze-thaw cycles.

Detection Antibody: Store at 4℃ and protect it from prolonged exposure to light for up to 6 months from date of receipt. DO NOT FREEZE!

Standard: Store lyophilized standard at -20℃ to -80℃ for up to 6 months from date of receipt. Aliquot and store the reconstituted standard at -80℃ for up to 1 month. Avoid repeated freeze-thaw cycles.
Ferret TNF ELISA Pair Set Standard Curve
TNF-alpha/TNFA/TNFSF2 Background

Tumor necrosis factor alpha (TNF-alpha), also known as TNF, TNFA or TNFSF2, is the prototypic cytokine of the TNF superfamily, and is a multifunctional molecule involved in the regulation of a wide spectrum of biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. Two receptors, TNF-R1 (TNF receptor type 1; CD120a; p55/60) and TNF-R2 (TNF receptor type 2; CD120b; p75/80), bind to TNF-alpha. TNF-alpha protein is produced mainly by macrophages, and large amounts of this cytokine are released in response to lipopolysaccharide, other bacterial products, and Interleukin-1 (IL-1). TNF-alpha is involved in fighting against the tumorigenesis, thus, is regarded as a molecular insight in cancer treatment.
