Also, Nick and I transformed DH5alpha comp cells from -80ºC iGEM box with extra pSB1AT3-J23100-Flu ligation Ben and Kevin made yesterday. Transformed according to [[Media:Direct Plating Transformation Protocol.pdf|Direct Plating Transformation Protocol]]. We also transformed ''P. putida'' and ''P. fluorescens'' with pSB1AT3 as a test. No dilutions were made. It was noted while plating the cells that the ''Pseudomonas'' strains somehow wound up with less than 50 uL of cells. And due to the cells flocculating during storage, the ''Pseudomonas'' strains also had be vortexed to resuspend the cells. |
