Atrosab
Based on 1 publication(s) in Google Scholar
Atrosab is a humanized IgG1 antagonistic anti-TNFR1 antibody. Atrosab inhibits TNF-mediated Apoptosis induction and IL-6 and IL-8 production. Atrosab reduces neurological deficits. Atrosab can be used for research of inflammatory disease. The recommend isotype control is Human IgG1 kappa, Isotype Control (HY-P99001).

Atrosab (0.1-1000 nM, preincubate with antibody for 1 h, then add the stimulant TNF and co-incubate for 7 hours) inhibits in a dose-dependent manner the TNF-induced apoptosis of Kym-1 cells [1].
Atrosab (0.1-1000 nM, preincubate with antibody for 1 h, then add the stimulant TNF and co-incubate for 7 hours) inhibits release of IL-6 from HeLa cells and IL-8 from HT1080 cells induced by TNF dose-dependently[1].
Atrosab (100 μg/mL,24 h) reduces endothelial cell expression of adhesion molecules and T cell adhesion[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Flow cytometric analysis of 1X106 FaDu cells with Atrosab (HY-P990008, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. AF 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa (HY-P99001, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black). -
Immobilized Human TNFR1,His Tag can bind Atrosab. The EC50 for this effect is 8.161 ng/mL. -
Loaded Atrosab on AHC2 biosensor, can bind TNFRSF1A Protein, Human (His, HY-P70801) with an affinity constant of 1.151E-08 M as determined in BLI assay.
