Sterile tissue culture plates

Manufactured by Corning
Sourced in United States

Sterile tissue culture plates are a type of laboratory equipment used for the in vitro cultivation of cells, tissues, or microorganisms. These plates provide a controlled and contamination-free environment for the growth and maintenance of these biological samples.

24 well sterile tissue culture plates (Corning, NY, USA) were coated with 4 µg/ml anti-CD3ε and 4 µg/ml anti-CD28 in 0.5 ml/well PBS at 37 °C for 2 h.
Purified CD4+ T-cells were washed using complete RPMI medium twice to eliminate the MACS buffer and then resuspended in complete RPMI media supplemented with 100 IU/ml recombinant human IL-2 (Peprotech; Rocky Hill, NJ, USA) and 5 ng/ml recombinant human TGF-β (Peprotech). 3 × 105 cells were added to the wells at a volume of 1 ml/well. Cells were cultured at 37 °C 5% CO2 for 3 days.

T Cell Differentiation and Expansion Protocols

Check if the same lab product or an alternative is used in the 5 most similar protocols
For iTreg and Tactivated cell differentiation, naive T cells were isolated and 24 well sterile tissue culture plates (Corning, Corning, NY) were coated anti-CD3ε (145–2C11, Biolegend) and anti-CD28 (37.51, Biolegend) as described 36 (link). Naive CD4+ T-cells were resuspended in complete RPMI media supplemented with 100 IU/ml recombinant human IL-2 for both iTreg and Tactivated, with additional 5 ng/ml recombinant human TGF-β for iTreg and 10 μg/ml anti-TGF-β (1D11.16.8, BioXcell, West Lebanon, NH) for Tactivated cultures. 3 × 105 cells were added to the wells at a volume of 1 ml/well. Cells were cultured at 37°C 5% CO2 for 3 days. Prior to experiments, live Tactivated and iTreg were FACS sorted based on their Foxp3-GFP expression status.
IL-2/anti–IL-2 mAb (JES6-1-A12, Bioxcell) complexes were prepared and injected as in 37 (link) to expand antigen-specific tTregs in vivo. Antigen-specific Tregs were isolated from spleens of the TCR transgenic animals by FACS sorting based on Foxp3 reporter expression. Alternatively, antigen-specific tTregs were expanded in vitro. For in vitro proliferation, Tregs were cultured for three days in the presence of plate bound anti-CD3ε (145–2C11; 2 ug/mL), anti-CD28 (37.51; 2 ug/mL) and IL-2 (100 U/mL). On day 3, cells were split 1:2 and cultured with only IL-2. Tregs were harvested on day 5 and FACS sorted for Foxp3 reporter.

6–8 weeks male Tipe2 KO and WT mice (five per experimental group) were sacrificed and spleens were collected into sterile complete RPMI. Single cell suspensions were obtained by mashing the spleen and passing cells through 70 μm cell strainer (BD, Franklin Lakes NJ, USA). Naïve CD4+ T cells were obtained according to the protocol of Miltenyi. 24 well sterile tissue culture plates (Corning, NY, USA) were coated with 4 μg/mL anti-CD3ε and 4 μg/mL anti-CD28 in 0.5 mL/well PBS at 37 °C for 2 h. Purified naïve CD4+ T cells which was isolated from Tipe2-/- or WT spleen were washed and resuspended in complete RPMI media supplemented with 100 IU/mL rhIL-2 (Peprotech, Cat#AF-200-02-10, Rocky Hill, NJ, USA) and 5 ng/mL rhTGF-β (Peprotech, Cat#100-21C-2). 3 × 105 cells were added to the wells at a volume of 1 mL/well. Cells were cultured at 37 °C 5% CO2 for 3 days and harvested for flow cytometry.

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.
