Despite low PBMC cell numbers, due to my ineffective media change, we were able to proceed with the virus addition as scheduled. Ash is confident that we will still get a few colonies.

First we transferred the PBMCs to a new 24-well plate with fresh media. The reprogramming process, as outlined previously, is deceptively simple and involved adding a specific volume of each viral vector (total of 3 vectors) to the PBMC culture. Thankfully, Ash calculated the miniscule amounts required.

The virus must be kept cold. As such, the 3 vials were collected and kept on ice during the transduction process.

After the virus was added, the PBMC culture was placed back in the incubator for 24 hours.
