Polystyrene petri dishes

Manufactured by Corning
Sourced in United Kingdom

Polystyrene petri dishes are a type of laboratory equipment used for culturing cells, microorganisms, and other biological samples. They provide a flat, sterile surface for growth and observation. The dishes are made of a clear, disposable polystyrene material and come in various sizes to accommodate different experimental needs.

Engineered Surfaces for Cell Adhesion

Non-tissue culture treated polystyrene petri dishes (Corning, Corning, NY) were enclosed using a single well FlexiPerm gasket (Sigma-Aldrich, St. Loius, MO). A solution of 2 μg mL−1 of Protein A/G (Themo-Fisher Scientific, Waltham, MA) and 1 μg mL−1 of SDF-1α (R&D Systems, Minneapolis, MN) was applied and incubated overnight at 4°C. The surfaces were then washed three times with PBS before a 30 minute incubation of a 0.2% w/v solution of Pluronic F-127 (Sigma-Aldrich). The surfaces were washed again three times with PBS. Next, a solution of ICAM-1/Fc and/or E-selectin/Fc chimera (R&D Systems) was applied to the surface and incubated for three hours at room temperature. The completed surfaces were then washed again three times with PBS before use. For experimentally tested points, molar ratios of 1:0, 10:1, 1:1, 1:10, and 0:1 E-selectin/Fc:ICAM-1/Fc were chosen to highlight differences between similar surfaces. In addition, total protein concentrations were chosen to yield total site densities of 4–5, 35–45, 130–160, 310–360, 550–610, and 1200–1300 sites/μm2.

The surfaces were then washed three times with PBS before a 30-minute incubation of a 0.2% w/v solution of Pluronic F-127 (Sigma-Aldrich). The surfaces were washed again three times with PBS. Next, a solution of 8 µg/mL ICAM-1/Fc and 2 µg/mL P-selectin/Fc chimeras (R&D Systems) was applied to the surface and incubated for three hours at room temperature. The completed surfaces were then washed again three times with PBS before use.

Cell Culture Protocols for HeLa, NIH/3T3, and Jurkat

Check if the same lab product or an alternative is used in the 5 most similar protocols
HeLa CCL-2 cells and NIH/3T3 cells (ATCC, Manassas, VA) were grown under standard incubation conditions at 37 °C and 5% CO2 in sterile-filtered DMEM with 10% heat-inactivated FBS, 2.5% HEPES, 1% Glutamine, and 1% Penicillin/Streptomycin (all Gibco). Jurkat cells were grown under the same conditions described above using RPMI 1640 complete medium instead of DMEM. Cells were plated onto T-75 flasks at 20% confluence and passaged every 3 days. For live and fixed-cell imaging experiments, cells were plated onto cell culture treated polystyrene Petri dishes (Corning).

Design and Validation of Nanovibrational Stimulation Apparatus

Check if the same lab product or an alternative is used in the 5 most similar protocols
The nanovibrational stimulation apparatus was nominally identical to that used by both Nikukar et al and Curtis et al (25, 26) . To perform experiments with 35 mm Petri dishes, six aluminium support discs were cut to 32 mm diameter, 3 mm thickness, polished (to ensure a smooth bonding surface). Six 35 mm tissue culture treated polystyrene Petri dishes (Corning, UK) were bonded onto the six aluminium discs using Loctite 2-part epoxy (Loctite, Hempstead, UK). Each cultureware assembly was subsequently bonded to a piezo transducer (model no. 010-05H Physik Instrumente, Karlsruhe/Palmbach, Germany) by application of a non-solvent glue (Bostik, UK). The transducers provided the required nanoscale amplitudes when driven by a continuous sine wave output from a GWINSTEK AFG-2005 arbitrary function generator (Good Will Instrument Euro B.V., Velhoven, Netherlands). The functionality of the piezo/cultureware assemblies was verified by incrementally driving each one at an audible frequency, i.e. 5 kHz, and listening to the audible output generated. The final set-up of the nanovibrational stimulation apparatus is shown in Figure 1.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
