Specificity The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product.
Characteristics The product does NOT contain any epitope tags. The protein has a calculated MW of 17.4 kDa. The protein migrates as 18 kDa on a SDS-PAGE gel under reducing (R) condition.
Purity >95 % as determined by reduced SDS-PAGE.
Sterility 0.22 μm filtered
Endotoxin Level Less than 1.0 EU per μg by the LAL method.
Grade Ultra Sensitive
ProductDetails: Biological Activity Comment Biological Activity: Measured by its binding ability in a functional ELISA.Immobilized Human TNFR1/CD120a Protein,C-Fc Tag (Catalog # TN1-H5251) at 5 μg/mL (100 μL/well) can bind Human TNF-alpha Protein, Biotinylated (Catalog # TNA-H8211) with a linear range of 0.8-10 ng/mL.

SDS-PAGE: The primary amine of Biotinylated TNFa was labeled by biotin for detection in ELISA, dot blot or western blot using streptavidin or avidin-conjugated probes.
Background Tumor necrosis factor alpha (TNFα) is a cytokine produced primarily by monocytes and macrophages. It is found in synovial cells and macrophages in the tissues.The primary role of TNFα is in the regulation of immune cells. TNFα is able to induce apoptotic cell death, to induce inflammation, and to inhibit tumorigenesis and viral replication. Dysregulation of TNFα production has been implicated in a variety of human diseases, including major depression, Alzheimer's disease and cancer. Recombinant TNFα is used as an immunostimulant under the INN tasonermin. TNFα can be produced ectopically in the setting of malignancy and parallels parathyroid hormone both in causing secondary hypercalcemia and in the cancers with which excessive production is associated.

Comment

A chemically labeled biotinylated protein with ultra sensitivity.
The product is produced using a chemical labeling approach. The primary amines in the side chains of lysine residues and the N-terminus of protein are conjugated with biotins.
Chemical labeling usually results in multiple biotin attachment on a single protein molecule, which could potentially lead to higher detection sensitivity.
