Mouse Spectrin alpha chain, brain (SPTAN1) ELISA Kit

Alpha-Fodrin is an intracellular, actin-binding, organ-specific protein of the cytoskeleton. The network of actin and fodrin situated below the plasma membrane of secretorial cells, is important for the alignment of secretorial vesicles to the plasma membrane during secretorial processes. During apoptosis the alpha-fodrin dimer is cleaved into a 120 kDa breakdown product, which is found abundantly in the salivary gland. This proteolysis of fodrin may be a consequence of protease activation during apoptosis. The cleavage product of 120 kDa alpha-fodrin was found to be an important autoantigen in the pathogenesis of organ-specific autoimmune esponse. Clinical studies have shown, that in patients with Sjögren Syndrome alpha-fodrin is involved in the stimulation of peripheral blood T-cells.

Mouse Spectrin alpha chain, brain (SPTAN1) ELISA Kit has high sensitivity and excellent specificity for detection of Mouse SPTAN1. No significant cross-reactivity or interference between Mouse SPTAN1 and analogues was observed.

This Mouse Spectrin alpha chain, brain (SPTAN1) ELISA Kit employs a two-site sandwich ELISA to quantitate SPTAN1 in samples. An antibody specific for SPTAN1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySPTAN1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SPTAN1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SPTAN1 bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.
