Detection of chrysotile asbestos by using a chrysotile ...
In the current studies, we found that the DksA protein from Escherichia coli binds strongly to chrysotile, which is the most commonly used form of asbestos. We developed a convenient colorimetric assay for chrysotile using a fusion of DksA and alkaline phosphatase along with 5-bromo-4-chloro-3-indol
