Immunofluorescent analysis of Metadherin in U2OS cells using a Metadherin recombinant rabbit oligoclonal antibody (Product # 710202) followed by detection using an Alexa Fluor 488-conjugated goat anti-rabbit secondary antibody (green) (Image A). Nuclei were stained using DAPI (Image B). Image C shows membrane-bound glycoconjugates on the cell surface stained with Alexa Fluor 594 wheat germ agglutinin (red). Image D is a composite image showing nuclear localization of Metadherin.

ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale and purified with Protein A.
ABfinity™ oligoclonal antibodies comprise a selection of multiple different recombinant monoclonal antibodies, providing the best of both worlds—the sensitivity of a polyclonal antibody with the specificity of a monoclonal, all delivered with the consistency only found in a recombinant antibody. While functionally the same as a polyclonal antibody—recognizing multiple epitope sites on the target and producing higher detection sensitivity for low abundance targets when compared with monoclonal antibodies—an oligoclonal antibody has a known mixture of light and heavy chains. This exact population can be produced in every lot, circumventing the biological variability typically associated with polyclonal antibody production.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
Metadherin (MTDH) was originally identified as an oncogene, and plays a role in promoting proliferation, invasion, survival, and enhancing chemoresistance. Expression of MTDH is associated with Ha-ras, PI3K/Akt, NF- kappaB and Wnt/ beta-catenin signaling pathways. Immunoflurescence and histochemical analysis has shown perinuclear, nucleolar, and cytoplasmic staining, while upregulated MTDH expression has been shown to enhance nuclear localization. The protein has three putative lysine-rich nuclear localization signals and this antibody has been raised specifically against the NLS3 region.
