GDF-15 Antibody (23B3.D2.H5) - C-terminus

Western Blot: GDF-15 Antibody (23B3D2.H5) [NBP1-42719] - Pichia pastoris whole cell lysates: lane 1 - yeast cell lysate expressing NAG-1 H variant with SUMO expression tag at 36 kDa; lane 2 - yeast cell lysate expressing NAG-1 D variant with SUMO expression tag at 36 kDa; lane 3 - yeast cell lysate expressing NAG-1 H variant; and lane 4 - yeast cell lysate expressing NAG-1 D variant. Recombinant NAG-1 proteins without SUMO correspond to monomer (15 kDa) and dimer (30 kDa) bands as indicated by the arrowheads. All lysates were run under reducing conditions. Primary antibody was used at a 1:1,000 dilution in TBS containing 1% BSA and 0.2% Tween, and reacted overnight at 4C. For detection, a 1:40,000 dilution of peroxidase conjugated Gt-a-Mouse IgG secondary antibody was used in Blocking Buffer for Fluorescent Western Blotting for 30 min at room temperature.

GDF-15 Antibody (23B3.D2.H5) - C-terminus Summary

• Description: This product was purified from concentrated tissue culture supernatant Protein A chromatography
  
  Store vial at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.
• Immunogen: This Protein A purified GDF-15 Antibody (23B3.D2.H5) was prepared by repeated immunizations with a synthetic peptide corresponding to a region near the carboxy terminal end of human GDF-15 protein. A residue of cysteine was added to facilitate coupling to KLH. (Uniprot: Q99988)
• Specificity: This antibody reacts with the C-terminus of endogenous GDF-15 protein from human tissues.
• Isotype: IgG1 Kappa
• Clonality: Monoclonal
• Host: Mouse
• Gene: GDF15
• Purity: Protein A purified

Applications/Dilutions

• Dilutions:
  • ELISA 1:2000
  • Western Blot 1:1000
• Application Notes: This Protein A purified This product has been tested by ELISA and western blotting for human NAG-1 protein. For detection of NAG-1 in human serum, a sandwich ELISA is suggested using this antibody in combination with anti-NAG-1/GDF15 (N-terminal), H variant or D variant specific antibodies. Specific conditions for reactivity should be optimized by the end user. Expect bands in Western blots of native protein of approximately 13 and 26 kDa in size corresponding to NAG-1 monomer and dimer, respectively, using the appropriate cell lysate or extract.

Reactivity Notes

A BLAST analysis suggests reactivity with GDF-15 from chimpanzee and macaque based on a 100% homology. Partial reactivity is expected against rat based on an 86% homology with the immunizing sequence. Cross-reactivity with GDF-15 from other sources has not been determined.

Background

Non-steroidal anti-inflammatory drug (NSAID) activated gene (NAG-1) is a member of the transforming growth factor-beta (TGF-beta) superfamily. NAG-1 is also known as Macrophage Inhibitory Cytokine-1 (MIC-1), Growth Differentiation Factor 15 (GDF15), Placental Bone Morphogenetic Protein (PLAB), or Prostate Derived Factor (PDF). NAG-1 is expressed in human placenta, prostate and colon. It possesses antitumorigenic and proapoptotic activities. NAG-1 expression is dramatically increased in inflammation, injury and malignancy. Increase of NAG-1 expression is a feature of many cancers including breast, colon, pancreas and prostate. In a number of studies, NAG-1 expression was increased by a number of NSAIDs. This increase in expression may correlate with the chemopreventive effect NSAIDs seem to have with certain cancers. NAG-1 expression is also induced by PPAR gamma ligands and by several dietary compounds such as conjugated linoleic acids (CLAs), naturally occurring fatty acids in ruminant food products, indoles, epicatechin gallate, and genistein. Induced expression of NAG-1 results in stimulation of apoptosis and inhibition of cell growth. Inhibition of NAG-1 induced expression by small interference RNA (siRNA) results in repression of induced apoptosis. NAG-1 expression is regulated by a numbers of transcription factors such as ERG-1 and Sp1. EGR-1 may be necessary for NSAID-induced NAG-1 expression. The study of expression of NAG-1 proteins, including variants, is important to define their potential role as serum biomarkers for cancer diagnosis, treatment monitoring, epidemiology study, and nutrition surveys.
