Nucleofected cells into flask, imaging dish. transformations |

Make 250 µL 1 mM STLC from 100 mM stock: (2.5 µL + 250 µL DMSO) Add 10 µL 1mM stock to each 2mL well to make 5 µM STLC |
|

||
| Sun | 11/3 | Tom treats coverslips with STLC | ||
| 10 | 17 | M | 11/3 | Morning: Kate fixes (4% PFA) coverslips from 11/3 Block by adding 10% BSA 15 min before class Make primaries: tubulin (rat) & Ki67 (rabbit) Make secondaries: Anti-rat green, anti-rabbit red New protocol New protocol for BSC fix and IF knockdown HeLa; image |
| 18 | W | 11/5 | Fixed cell analysis to look for loss of Ki-67 and for the chromosome phenotype |
|
| 11 | 19 | M | 11/10 | Prepare plasmids for Gibson assembly reactions Restriction digest of PX458GFP, 2 per group in pcr tubes, in thermocycler. One uncut plasmid for control (Bbs1) (new from NEB freezer 10/31/25 R3539S) Small is available at NEBNow, need 2 or special order the large. Clone construct, prep vector 1% gel NEB 1Kb marker and gel extraction kit (1 per group – students combine their 2 cut plasmids) Nanodrop Traces are weird – unknown peak at about 245 nm, 260/280 ratios as high as 20! |
| 20 | W | 11/12 | Gibson assembly (isothermal) reaction with chosen DNA from Twist and PX458GFP *Magic Mix 15 µL: (enzymes from “Maresca” box) • T5 exonuclease • Phusion polymerase • Taq ligase Cut plasmid 50 – 100 ng Insert equimolar amount (we will measure this for you) DNAse-free water up to 20 µL Incubate at 50°C for 15 minutes Transform 5-10 µL of reaction into competent E. coli cells bacterial Transformation |
