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 PRPH2 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.

MBS9316624 is a ready-to-use microwell, strip plate ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the peripherin 2 (retinal degeneration, slow) (PRPH2) 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 PRPH2. The ELISA analytical biochemical technique of the MBS9316624 kit is based on PRPH2 antibody-PRPH2 antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect PRPH2 antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, PRPH2. 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(%).

PRPH2_HUMAN

The protein encoded by this gene is a member of the transmembrane 4 superfamily, also known as the tetraspanin family. Most of these members are cell-surface proteins that are characterized by the presence of four hydrophobic domains. The proteins mediate signal transduction events that play a role in the regulation of cell development, activation, growth and motility. This encoded protein is a cell surface glycoprotein found in the outer segment of both rod and cone photoreceptor cells. It may function as an adhesion molecule involved in stabilization and compaction of outer segment disks or in the maintenance of the curvature of the rim. This protein is essential for disk morphogenesis. Defects in this gene are associated with both central and peripheral retinal degenerations. Some of the various phenotypically different disorders are autosomal dominant retinitis pigmentosa, progressive macular degeneration, macular dystrophy and retinitis pigmentosa digenic.

PRPH2: May function as an adhesion molecule involved in stabilization and compaction of outer segment disks or in the maintenance of the curvature of the rim. It is essential for disk morphogenesis. Defects in PRPH2 are the cause of retinitis pigmentosa type 7 (RP7). RP leads to degeneration of retinal photoreceptor cells. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. Defects in PRPH2 are a cause of retinitis punctata albescens (RPA). Defects in PRPH2 are a cause of *****-onset vitelliform macular dystrophy (AVMD). AVMD is a rare autosomal dominant disorder with incomplete penetrance and highly variable expression. Patients usually become symptomatic in the fourth or fifth decade of life with a protracted disease of decreased visual acuity. Defects in PRPH2 are a cause of patterned dystrophy of retinal pigment epithelium (PDREP). Patterned dystrophies of the retinal pigment epithelium (RPE) refer to a heterogeneous group of macular disorders. Three main types of PDREP have been described: reticular (fishnet-like) dystrophy, macroreticular (spider-shaped) dystrophy and butterfly-shaped pigment dystrophy. Defects in PRPH2 are a cause of choroidal dystrophy central areolar type 2 (CACD2). It is a disorder which affects the posterior pole of the eye, and early lesions consist of a non-specific area of granular hyperpigmentation at the fovea. The characteristic sign of the disorder, a zone of atrophy that develops in the macula of the eye and involves the retinal pigment epithelium and the choriocapillaris, occurs several decades after onset. Defects in PRPH2 are found in different retinal diseases including cone-rod dystrophy, retinitis pigmentosa, macular degeneration. The mutations underlying autosomal dominant retinitis pigmentosa and severe macular degeneration are largely missense or small in-frame deletions in a large intradiscal loop between the third and fourth transmembrane domains. In contrast, those associated with the milder pattern phenotypes or with digenic RP are scattered more evenly through the gene and are often nonsense mutations. This observation correlates with the hypothesis that the large loop is an important site of interaction between PRPH2 molecules and other protein components in the disk. Belongs to the PRPH2/ROM1 family.
