Principle of the Assay: The microtiter plate provided in this kit has been pre-coated with an antibody specific to Fibrillin-2. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated polyclonal antibody preparation specific for Fibrillin-2 and Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Only those wells that contain Fibrillin-2, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm +/- 2 nm. The concentration of Fibrillin-2 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is a component of connective tissue microfibrils and may be involved in elastic fiber assembly. Mutations in this gene cause congenital contractural arachnodactyly. [provided by RefSeq, Jul 2008]
Uniprot Description
FBN2: Fibrillins are structural components of 10-12 nm extracellular calcium-binding microfibrils, which occur either in association with elastin or in elastin-free bundles. Fibrillin-2- containing microfibrils regulate the early process of elastic fiber assembly. Regulates osteoblast maturation by controlling TGF-beta bioavailability and calibrating TGF-beta and BMP levels, respectively. Defects in FBN2 are the cause of distal arthrogryposis type 9 (DA9). A form of distal arthrogryposis, a disease characterized by congenital joint contractures that mainly involve two or more distal parts of the limbs, in the absence of a primary neurological or muscle disease. DA9 is a connective tissue disorder characterized by contractures, arachnodactyly, scoliosis, and crumpled ears. Belongs to the fibrillin family. 2 isoforms of the human protein are produced by alternative splicing.

Product Notes
The Human FBN2 fbn2 (Catalog #AAA9428644) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA9428644 ELISA Kit recognizes Human FBN2. It is sometimes possible for the material contained within the vial of "Fibrillin-2, 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
