#Collect trypsinized cells from each small well: use 3.5 mL medium, pipette up and down to make an even cell suspension. Transfer into the 6mL medium in one of the 10 cm plates. Spread cells by moving plate up/down/back/forth. Repeat for two remaining samples. | |||

SummaryThe transfection from earlier in the week had a very low efficiency, but we're going to expand that cell line just in case, transferring the cells into 10cm petri dishes. Meanwhile, we'll also be setting up another batch of U2OS cells for transfection by advancing them to another 6 well plate, as well as passaging the line from PS-1 to PS-2. Lastly, we'll be using the PS-1 backup flask to create more frozen stock of U2OS. Goals
