Principle of the Assay: CLN3 ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-CLN3 antibody and an CLN3-HRP conjugate. The assay sample and buffer are incubated together with CLN3-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the CLN3 concentration since CLN3 from samples and CLN3-HRP conjugate compete for the anti-CLN3 antibody binding site. Since the number of sites is limited, as more sites are occupied by CLN3 from the sample, fewer sites are left to bind CLN3-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The CLN3 concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a protein that is involved in lysosomal function. Mutations in this, as well as other neuronal ceroid-lipofuscinosis (CLN) genes, cause neurodegenerative diseases commonly known as Batten disease or collectively known as neuronal ceroid lipofuscinoses (NCLs). Many alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2008]
Uniprot Description
CLN3: Involved in microtubule-dependent, anterograde transport of late endosomes and lysosomes. Defects in CLN3 are the cause of neuronal ceroid lipofuscinosis type 3 (CLN3); also known as Batten disease. A form of neuronal ceroid lipofuscinosis. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. The hallmark of CLN3 is the ultrastructural pattern of lipopigment with a fingerprint profile, which can have 3 different appearances: pure within a lysosomal residual body; in conjunction with curvilinear or rectilinear profiles; and as a small component within large membrane-bound lysosomal vacuoles. The combination of fingerprint profiles within lysosomal vacuoles is a regular feature of blood lymphocytes from patients with CLN3. Belongs to the battenin family. 5 isoforms of the human protein are produced by alternative splicing.

Product Notes
The Human CLN3 cln3 (Catalog #AAA7206914) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA7206914 ELISA Kit recognizes Human CLN3. It is sometimes possible for the material contained within the vial of "Battenin (CLN3), ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
