Specificity and Use

PDCD4 antibody was raised against synthetic peptide from human PDCD4.
Amino acids 447-465 of human Pdcd4 protein.
Immunohistochemistry: LS-B487 was validated for use in immunohistochemistry on a panel of 21 formalin-fixed, paraffin-embedded (FFPE) human tissues after heat induced antigen retrieval in pH 6.0 citrate buffer. After incubation with the primary antibody, slides were incubated with biotinylated secondary antibody, followed by alkaline phosphatase-streptavidin and chromogen. The stained slides were evaluated by a pathologist to confirm staining specificity. The optimal working concentration for LS-B487 was determined to be 1.25-2.5 ug/ml.


0.02 M potassium phosphate, 0.15 M sodium chloride, pH 7.2, 0.01% sodium azide.
Long term: -20°C; Short term: +4°C. Avoid repeat freeze-thaw cycles.
For research use only.

This gene encodes a protein localized to the nucleus in proliferating cells. Expression of this gene is modulated by cytokines in natural killer and T cells. The gene product is thought to play a role in apoptosis but the specific role has not yet been determined. Two transcripts encoding different isoforms have been identified. PDCD4 inhibits the translation initiation factor E1F4A.

Western Blot

Western Blot
Anti-Pdcd4 pS457 - Western Blot. Western blot of affinity purified anti-Pdcd4 pS457 antibody shows detection of Pdcd4 phosphorylated at Ser 457 (arrowheads). Lanes 1 & 2 each contain 100 ng recombinant Pdcd4. Lanes 3 & 4 each contain 30 ug of whole cell extract from 293 HEK cells treated with 20 nM TPA and MG132 proteosome inhibitor for 8 hours. The signal can be competed off with peptide phosphorylated at Ser 457 (Lanes 2 & 4). Personal Communication, M Young & A Jansen, NCI, Bethesda, MD.
