Principle of the Assay: BEST1 ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-BEST1 antibody and an BEST1-HRP conjugate. The assay sample and buffer are incubated together with BEST1-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 BEST1 concentration since BEST1 from samples and BEST1-HRP conjugate compete for the anti-BEST1 antibody binding site. Since the number of sites is limited, as more sites are occupied by BEST1 from the sample, fewer sites are left to bind BEST1-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The BEST1 concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a member of the bestrophin gene family. This small gene family is characterized by proteins with a highly conserved N-terminus with four to six transmembrane domains. Bestrophins may form chloride ion channels or may regulate voltage-gated L-type calcium-ion channels. Bestrophins are generally believed to form calcium-activated chloride-ion channels in epithelial cells but they have also been shown to be highly permeable to bicarbonate ion transport in retinal tissue. Mutations in this gene are responsible for juvenile-onset vitelliform macular dystrophy (VMD2), also known as Best macular dystrophy, in addition to adult-onset vitelliform macular dystrophy (AVMD) and other retinopathies. Alternative splicing results in multiple variants encoding distinct isoforms.[provided by RefSeq, Nov 2008]
Uniprot Description
BEST1: Forms calcium-sensitive chloride channels. Highly permeable to bicarbonate. Defects in BEST1 are the cause of vitelliform macular dystrophy type 2 (VMD2); also known as Best macular dystrophy (BMD). VMD2 is an autosomal dominant form of macular degeneration that usually begins in childhood or adolescence. VMD2 is characterized by typical 'egg-yolk' macular lesions due to abnormal accumulation of lipofuscin within and beneath the retinal pigment epithelium cells. Progression of the disease leads to destruction of the retinal pigment epithelium and vision loss. Defects in BEST1 are the cause of retinitis pigmentosa type 50 (RP50). A retinal dystrophy belonging to the group of pigmentary retinopathies. RP is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. 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 BEST1 are a cause of adult-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 BEST1 are the cause of bestrophinopathy autosomal recessive (ARB). A retinopathy characterized by central visual loss, an absent electro-oculogram light rise, and a reduced electroretinogram. Defects in BEST1 are the cause of vitreoretinochoroidopathy autosomal dominant (ADVIRC). A disorder characterized by vitreoretinochoroidal dystrophy. The clinical presentation is variable and may be associated with cataract, nanophthalmos, microcornea, shallow anterior chamber, and glaucoma. Belongs to the bestrophin family. 3 isoforms of the human protein are produced by alternative splicing.

Product Notes
The Human BEST1 best1 (Catalog #AAA7231054) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA7231054 ELISA Kit recognizes Human BEST1. It is sometimes possible for the material contained within the vial of "Bestrophin 1 (BEST1), 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
