Application

Human TNF-alpha Protein, His Tag AIDD-Ready protein is designed for direct use in SPR assays. It is supplied in a sugar-free, glycerol-free formulation to eliminate refractive index interference in SPR. No desalting or buffer exchange is required before use, simplifying the SPR workflow and supporting high-throughput experimental validation to accelerate the transition from AI prediction to wet-lab validation.

Features and Advantages
  • Directly compatible with SPR: No desalting or buffer exchange required; supplied as a liquid to reduce sample preparation and improve experimental efficiency.
  • High batch-to-batch consistency: Each lot is released using SPR QC to ensure experimental reproducibility.
  • Validated with representative drugs: SPR binding activity is validated using representative drug antibodies to ensure suitability for drug screening and evaluation.
Synonyms

DIF, TNF-alpha, TNFA, TNFSF2, cachexin, cachectin, TNFα

Source

Human TNF-alpha Protein, His Tag (TNA-H5228AI) is expressed from human 293 cells (HEK293). It contains AA Val 77 - Leu 233 (Accession # P01375-1).

Predicted N-terminus: Val 77

Molecular Characterization

This protein carries a polyhistidine tag at the C-terminus.

The protein has a calculated MW of 18.3 kDa. The protein migrates as 17-18 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE).

The protein is designed as a trimer.

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.
