Product overview
Cleaved Tau ELISA Kit (Human Asp738/Mouse Asp713) (ab269557) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Cleaved Tau (Human Asp738/Mouse Asp713) protein in cell culture supernatant, cell lysate, edta plasma, serum, cit plasma, hep plasma, tissue extracts, and cell culture media. It uses our proprietary SimpleStep ELISA® technology. Quantitate Cleaved Tau (Human Asp738/Mouse Asp713) with 0.075 ng/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
– Single-wash protocol reduces assay time to 90 minutes or less
– High sensitivity, specificity and reproducibility from superior antibodies
– Fully validated in biological samples
– 96-wells plate breakable into 12 x 8 wells stripsA 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Notes
Tau promotes microtubule assembly and stability; it might be involved in the establishment and maintenance of neuronal polarity. The C-terminus of Tau binds axonal microtubules while the N-terminus binds neural plasma membrane components, suggesting that Tau functions as a linker protein between both. Axonal polarity is predetermined by Tau localization (in the neuronal cell) in the domain of the cell body defined by the centrosome. Tau is expressed predominantly in neurons. Human Tau is expressed at least as 9 isoforms. The long PNS-tau isoform is expressed in the peripheral nervous system while the others are expressed in the central nervous system. The short isoforms allow plasticity of the cytoskeleton whereas the longer isoforms may preferentially play a role in its stabilization. Tau is phosphorylated at various serine and threonine residues. Tau phosphorylation impairs the Tau ability to bind microtubules and leads to microtubule depolymerization. Hyperphosphorylated Tau is the major component of paired helical filaments, the building block of neurofibrillary lesions in Alzheimer’s disease (AD) brain. Tau truncation can affect Tau pathologic characteristics, including its ability to acquire AD-related conformations and to assemble into filaments. Amyloid-beta protein can trigger caspase activation and cellular apoptosis. Several activated caspases, including caspase-3, caspase-7, and caspase-8, can cleave Tau at a highly conserved sequence present in all isoforms generating Cleaved Tau with …SSTGSIDMVD sequence at the carboxy terminus. This carboxy terminal Asp corresponds to, for example, Asp738 of human canonical PNS isoform, Asp421 of human Tau-F isoform, or Asp713 of mouse canonical PNS isoform. The cleavage of Tau at this site is an important inducer of Tau polymerization in AD. This kit is designed to detect all Tau isoforms only when cleaved at the above described site.

UncategorizedIgA Antibody
Original price was: $780.00.$650.00Current price is: $650.00. Add to cartIgA antibody is the most abundant antibody class in human serum and has a unique role in mediating immunity. IgA is a polyvalent antibody that is translocated to mucosal surfaces as the first line of defence against infections. Most of the secreted IgA lines the mucosal surfaces including respiratory, digestive and genitourinary tracts to protect against pathogens while maintaining gut homeostasis.
The importance of IgA in pathogen defence is highlighted by the numerous mechanisms used by pathogens to neutralize sIgAs, including sIgA-binding proteins and sIgA-specific proteases produced by certain pneumococci, neisseriae and haemophilus species of bacteria.
IgA Antibody Structure and Format
IgA antibodies consists of heavy (H) and light (L) chains. Each H chain is comprised of the Constant region (Cα1, Cα2, Cα3), hinge region and the Variable (V) region. Light chains consists of the CL and Vκ or Vλ elements. Altogether the combined molecular weight of IgA antibody is ~160 kDa. IgA antibodies possess a unique 18-amino acid tail piece at the C-terminus of the H chains which is key for oligomerization. As in the case of IgM antibody, IgA antibody monomers routinely dimerize with the help of a 15 kDa J chain. The secreted form of IgA (sIgA) is usually dimeric and contains an additional 80-85 kDa component.
