实验试剂
Heat inactivated Fetal Calf Serum (FCS). Recombinant mouse IL-2 (human IL-2 can also be used).
实验设备
Flat bottom tissue culture plates or tissue culture flasks of suitable size.
实验步骤
1. Dynabeads Washing Procedure
Dynabeads should be washed before use.
1) Resuspend the Dynabeads Mouse T-Activator CD3/CD28 in the vial.
2) Transfer the desired volume of Dynabeads to a tube.
4) Place the tube on a magnet for 1 min and discard the supernatant.
2. Activation of Mouse T Cells
1) Start with 8 × 104 purified T cells in 100-200 µl medium in a 96-well tissue culture plate.
5) Transfer the supernatant containing the cells to a new tube.
2) Add Dynabeads Mouse T-Activator CD3/CD28 at a bead-to-cell ratio of 1:1.
6) Count the cells at least twice weekly after thorough re-suspension.
2) Add Dynabeads Mouse T-Activator CD3/CD28 at a bead-to-cell ratio of 1:1.
4) Incubate in a humidified CO2 incubator at 37°C for the length of your specific experiment.
6) Count the cells at least twice weekly after thorough re-suspension.
5. Expansion of Mouse Regulatory T Cells
2) Add Dynabeads Mouse T-Activator CD3/CD28 at a bead-to-cell ratio of 2:1.
4) Incubate in a humidified CO2 incubator at 37°C for the length of your specific experiment.
6) Count the cells at least twice weekly after thorough re-suspension.
8) Treg cells retain FoxP3 expression after 2 weeks expansion.
注意事项
2. This product should not be used with Dynal MPC™-1.
3. Never use less than the recommended volume of Dynabeads.
4. Carefully follow the recommended pipetting volumes.
