Thawing of eukaryotic cells

New Phoenix cell stocks were thawed:

cryotube was thawed at 37°C water bath until almost defrosted
stock was filled in 9 ml warm completed growth medium and centrifuged at 900 rpm for 2 min
medium was removed and refilled with 10 ml warm completed growth medium
cells were seeded on 100 mm plates

Testing optimal cell density of mouse fibroblasts

NIH 3T3 have a really fast growth so that we tested the optimal cell number for seeding NIH 3T3 for having around 60% cell density on the next day. NIH 3T3 cells grow very fast; therefore we have tested the optimal seeding cell number to obtain 60% cell density on the next day. Results indicate that the optimal cell number is 1 &ndash 1.5x10^5 cells per well ( = 0.5 – 0.75 cells/ml)

Transduction mouse cells (different incubation times)

NIH 3T3 cells (60% density) were transduced with MuLV IRES EGFP and incubated for 8, 16, 24 and 2 x 8 hours. Virus was taken from different supernatants (an older one and a newer one) to see, if it makes any difference. Cells were infected with supernatant (500µl viral supernatant, 500µl completed growth medium + 1µl Polybrene/ml) harvested at different time points. Results indicate that there was no difference between older and newer virus; best results were given with an infection time of 2 x 8 hours.

For testing, if centrifugation brings better transduction efficiencies, mouse cells were infected with the different viral supernatants and centrifuged for 45 min, 1800 rpm, 32°C. In two wells it was tested if the double amount of Polybrene brings better transduction efficiencies. However, we found out that cells were death after centrifugation.

Transfection of HEK cells with receptor

HEK293 were transfected with the receptor plus mCherry to see, if the virus infect only cells expressing the receptor (the two plasmids should infect same cells). In parallel cells were transfected with the blue light and the red light positive control (PMZ422 and PSAM200) and the receptor inducible by the light systems. After 24 h cells (expressing the receptor) were infected with MuLV IRES EGFP.

The light induced receptor was induced by light scatter.

HEK293T cells were transfected with the light system and the light induced receptor (p14ls_003) labeled with mCherry. Cells were illuminated using a photo mask that covered parts of the cell culture and prevented them from light exposure. However, the receptor expression was activated also outside of the pattern.

-<p>It looked like ePDZb hadn&rsquo;t been totally digested. The second lane lay short under 1 kb lane and not at 600 bp. WPRE RFC 10, SEAP RFC 10 and P2A didn&rsquo;t show expected results. Especially it seemed that SEAP RFC 10 was actually identical with GAL 4 RFC 25 due to the lanes at 500 bp, which were expected for GAL4 RFC 25.</p>

-<p>Eight colonies from containing PCR 40 were picked for ONC.</p>
