Description PRINCIPLE OF THE ASSAY This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant human VEGFA has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Ranibizumab in the sample competitively binds to the pre-coated protein with biotin-labeled Ranibizumab. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in inversely proportion to the amount of Ranibizumab bound in the initial step. The color development is stopped and the intensity of the color is measured.
Applications Used for the quantitative determination of Ranibizumab concentration in serum and plasma.
Stability and Storage When the kit was stored at the recommended temperature for 6 months, the signal intensity decreased by less than 20%.

Background Ranibizumab is a monoclonal antibody fragment (Fab) created from the same parent mouse antibody as bevacizumab. Ranibizumab was developed by Genentech and is marketed in the United States by Genentech and elsewhere by Novartis, under the brand name Lucentis. Ranibizumab is used to treat wet age-related macular degeneration (AMD; an ongoing disease of the eye that causes loss of the ability to see straight ahead and may make it more difficult to read, drive, or perform other daily activities). It is also used to treat macular edema after retinal vein occlusion (an eye disease caused by blockage of blood flow from the eye that leads to blurry vision and vision loss), diabetic macular edema (an eye disease caused by diabetes that can lead to vision loss), and diabetic retinopathy (damage to the eyes caused by diabetes). It inhibits angiogenesis by inhibiting Vascular endothelial growth factor A (VEGF-A), and its effectiveness is similar to that of bevacizumab. Its rates of side effects also appear similar. However, ranibizumab typically costs $2,000 a dose, while the equivalent dose of bevacizumab typically costs $50.
