Human TWEAK/TNFSF12 Antibody

• Species Reactivity
  Human
• Specificity
  Detects human TWEAK in direct ELISAs and Western blots. In direct ELISAs, less than 5% cross-reactivity with recombinant human (rh) BAFF, rhFas Ligand, rhGITR Ligand, rhOX40 Ligand, rhTRAIL and less than 1% cross-reactivity with rhAPRIL, rhLIGHT, rhTNF-alpha, rhVEGI, and rhTRANCE is observed.

• Neutralization
  Measured by its ability to neutralize TWEAK/TNFSF12-induced inhibition of proliferation in the HT‑29 human colon adenocarcinoma cell line. Yu, K. Y. et al. (1999) J. Biol. Chem. 274:13733; Harrop, J. A. et al. (1998) J. Biol. Chem. 273:27548The Neutralization Dose (ND₅₀) is typically 2-8 µg/mL in the presence of 1  µg/mL Recombinant Human TWEAK/TNFSF12.

TWEAK/TNFSF12 Inhibition of Cell Proliferation and Neutralization by Human TWEAK/TNFSF12 Antibody. Recombinant Human TWEAK/TNFSF12 (Catalog # 1090-TW) inhibits proliferation in the the HT‑29 human colon adenocarcinoma cell line in a dose-dependent manner (orange line). Activity elicited by Recombinant Human TWEAK/TNFSF12 (1  µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human TWEAK/ TNFSF12 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1090). The ND50 is typically 2-8 µg/mL.

TWEAK/TNFSF12 in MDA-MB-231 Human Cell Line. TWEAK/TNFSF12 was detected in immersion fixed MDA-MB-231 human breast cancer cell line using 10 µg/mL Goat Anti-Human TWEAK/TNFSF12 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1090) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).
