The \u201cBoot Pocket\u201d named invention herein is a pair of cuffs that surrounds and secures to a pair of boots by means of a multiple fastener zipper system. The pH sensor comprises a substrate and an ion sensitive field effect transistor die comprising an ion sensing part that responds to pH, wherein the ISFET die is located over the substrate. The striker plate can also function adjacent other corrosive areas in a tank, such as along a seam in a tank wall, to reduce corrosion. Furthermore, the invention relates to antibodies directed to polypeptides according to the present invention and to pharmaceutical compositions and diagnostic reagents comprising such antibodies, polypeptides or polynucleotides.
