Background: Alkaline Phosphatases (phoA) are ubiquitous membrane bound glycoprotiens that catalyze the hydrolysis of phosphate monoesters at basic pH levels with release of inorganic phosphate(2). They are used as reporter enzymes in different assays such as Western Blotting and in situ hybridization(3). The phoA was linked to the ScFv sequence as a chromogenic reagent, meaning the when the phoA is mixed with with 5-Bromo-4-Chloro-3-indolyl phosphate  (BCIP) expresses a blue color in the 615 nm range which is visible to the naked eye. Alkaline phosphatase is linked to the C-terminus of the ScFv’s light chain through (GGGS) [glycine] linkers. Thus, the ScFv is responsible for binding to OspA and will only express color if once the ScFv binds to the target OspA protein.
