The mechanical performance was evaluated under three curing environments (laboratory conditions, wet chamber, and outer environment) to represent different conditions concrete may be subject to.
1.1 ml of this cell suspension were plated in triplicate into 35 mm Petri dishes (Greiner Bio-One, Frickenhausen, Germany) and incubated in a wet chamber at standard cell culture conditions.
A large number of tensile, compression and bending tests were carried out in two conditions, dry (in terms of the environment) and wet (after 3 weeks in wet chamber).
It is shown that both, Tonkin Cane and Ku Zhu, in spite of low change in weight after 3 weeks in wet chamber have lower values of mechanical properties.
The functionality of the immobilized antibodies with the Protein A method was tested with S.typhimurium in a wet chamber and the frequency decrease was compared to results of a similar system activated with PEI GA immobilization.
Slides were blocked for 1 h in blocking buffer (10% v/v goat serum, 1% w/v BSA in PBS) followed by overnight incubation with 4B7 mAb (1 500) or test antiserum (1 1000) in 1% (w/v) BSA in PBS at 4 °C in a wet chamber.
The slide was incubated at room temperature for 10 15 min in a wet chamber (covered with aluminium foil), and unattached cells were washed off gently with PBS.
Additional sections were incubated with terminal deoxynucleotidyl transferase (TdT), a fluorescein-labeled nucleotide mixture, in a wet chamber at 37°C for 1 hr.
This depression was filled with a 1 1 mixture of cornmeal agar and 1% agarose for two days in a wet chamber at 27°C.
Afterwards, the microarrays were incubated for 16 h in a wet chamber to ensure efficient covalent binding of the oligonucleotides to the surface.
The hemocyte pellet was resuspended in PBS, and deposited on clean slides (a drop on each) in the wet chamber for 1 h.
