Select online data sheet information is drawn from bioinformatics databases, occasionally resulting in ambiguous or non-relevant product information. It is the responsibility of the customer to review, verify, and evaluate the information to make sure it matches their requirements before purchasing the kit. Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved. If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order. We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual.

Small volumes of DSPP elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS059325 is a ready-to-use microwell, strip-or-full plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Dentin Sialophosphoprotein (DSPP) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing DSPP. The ELISA analytical biochemical technique of the MBS059325 kit is based on DSPP antibody-DSPP antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect DSPP antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, DSPP. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

DSPP_HUMAN

This gene encodes two principal proteins of the dentin extracellular matrix of the tooth. The preproprotein is secreted by odontoblasts and cleaved into dentin sialoprotein and dentin phosphoprotein. Dentin phosphoprotein is thought to be involved in the biomineralization process of dentin. Mutations in this gene have been associated with dentinogenesis imperfecta-1; in some individuals, dentinogenesis imperfecta occurs in combination with an autosomal dominant form of deafness. Allelic differences due to repeat polymorphisms have been found for this gene. [provided by RefSeq, Jul 2008]

DSPP: DSP may be an important factor in dentinogenesis. DPP may bind high amount of calcium and facilitate initial mineralization of dentin matrix collagen as well as regulate the size and shape of the crystals. Defects in DSPP are the cause of deafness autosomal dominant type 39 with dentinogenesis imperfecta 1 (DFNA39/DGI1). Affected individuals present DGI1 associated with early onset progressive sensorineural high-frequency hearing loss. Defects in DSPP are the cause of dentinogenesis imperfecta type 1 (DGI1); also known as dentinogenesis imperfecta Shields type 2 (DGI2). DGI1 is an autosomal dominant disorder in which both the primary and the permanent teeth are affected. It occurs with an incidence of 1:8000 live births. The teeth are amber and opalescent, the pulp chamber being obliterated by abnormal dentin. The enamel, although unaffected, tends to fracture, which makes dentin undergo rapid attrition, leading to shortening of the teeth. Defects in DSPP are a cause of dentinogenesis imperfecta Shields type 3 (DGI3). Patients with DGI3 do not have stigmata of osteogenesis imperfecta. The finding that a single defects in the DSPP gene causes both phenotypic patterns of DGI2 and DGI3 strongly supports the conclusion that these two disorders are not separate diseases but rather the phenotypic variation of a single genetic defect. Defects in DSPP are the cause of dentin dysplasia type 2 (DTDP2); also known as dentin dysplasia Shields type 2. DTDP2 is an autosomal dominant disorder in which mineralization of the dentine of the primary teeth is abnormal. On the basis of the phenotypic overlap between, and shared chromosomal location with DGI2 it has been proposed that DTDP2 and DGI2 are allelic. From the results of recent studies, it is clear that different types of mutations in DSPP lead to the two different phenotypes.
