A method includes introducing a treatment fluid into a wellbore penetrating a subterranean formation, the treatment fluid including a polymer gel having a water-soluble polymer, a proppant, and a polymer gel-preserving amount of chlorine dioxide, the placing step includes applying the treatment fluid at a sufficient pressure and at a sufficient rate to fracture the subterranean formation. Each of the syringes for attachment to the syringe interface includes at least one mounting flange, and each of the plurality of syringes has a different mounting flange dimension. The first and second side flaps are folded over the second panel for closing the sides of the box. The molecules regulate gene expression in the bacterium.
