Transfer the intestine to a 50 mL tube (n4) containing the 10mL digestion medium (at 37). Just like for the IEL isolation protocol: Incubate the 50mL falcon tubes at 37 and 220 rpm for 15 min. (inside plastic beakers–4 tubes or within a falcon tube help fixed to the shaker plate) Following incubation, using a plastic transfer-pipet pipet up and down the option containing the intestine. With all the identical transfer-pipet transfer the option and filter it via a 70m cell strainer placed on new 50mL tube (n5) containing ice cold total T cell Medium + 100L of 4mM EDTA. Gather the tissue within the cell strainer and repeat the process in measures two, two much more instances (applying the exact same tube n4). After filtering the last time, having a syringe lid (green) smash the pieces of tissue left behind inside the strainer adding some a lot more 4 complete T cell medium.
