Immunofluorescence analysis of Tau (red) in human glutamate neurons derived from iPSCs. The cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with 0.2% Triton X-100 in PBS for 10 minutes, and blocked with 5% donkey serum in PBS for 15 minutes at room temperature. Cells were stained with a Tau rabbit oligoclonal antibody (Product # 710080) at 1:500 and a Map2 monoclonal antibody (Product # MA5-12826) diluted at 1:1000 in 5% donkey serum overnight at 4°C, and then incubated with a Goat anti-rabbit IgG (H+L) secondary antibody, Alexa Fluor 546 conjugate (Product # A11010, red)) and Goat anti-Mouse IgG (H+L), Alexa Fluor® 488 conjugate (Product # A28175, green) at a dilution of 1:1000 for 1 hour at room temperature.

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.
710080 was used to successfully detect Tau protein in human glutamate neurons derived from iPSCs.
Tau protein plays a very important role in nucleation and stabilization of microtubules by associating with tubulin subunits. In humans, Tau is predominantly expressed in the brain, and is involved in neurodegeneration when the protein is misfolded, hyperphosphorylated, or self-assembles into tangles. Six isoforms of Tau with varying degree of affinity to tubulin exist. Numerous serine/threonine kinases, including GSK-3 beta, protein kinase A, and casein kinase II (CK2) phosphorylate Tau. Phosphorylation of the serine 396 residue is triggered through GSK-3beta and cdk5. The gene encoding the Tau protein consists of 16 exons, and is located at chromosomal locus 17q21.
