    In situ Novocrania and Terebratalia 


    Warning: preg_match_all(): Compilation failed: invalid range in character class at offset 7 in /home/customer/www/phd.organelas.com/public_html/wp-content/themes/p2/inc/mentions.php on line 77

    In situ using Nano longer probes to try to get a better signal to ratio. Also fgf8 probe, important for the brain boundary. I also need better hedgehog pictures, so I’m repeating the in situ with a new probe in Ttra and also trying to get a good early gastrula, bilateral gastrula e late larvae of engrailed.

    Nano wnt5 Nano smo2 Nano fgf8 Nano ptc1
    Ttra hh Ttra en late blastula / early gastrula Ttra en bilateral gastrula / late larva

    10 min ProtK for all. Incubated at 65 °C at 2000.

    31/01/2015

    Diluted probes to 1 ng/µL and added at 0800.

    02/02/2015

    First day of washes. Added anti-dig-ap at 1600.

    03/02/2015

    Washed off antibody with 3x 5min followed by 4x 15 min and 5x 30 min. Developed with nbt/bcip at 1600. All wells showed good signal/noise ratio. The worst is wnt5, but it is still better than the other in situ. I exchanged the AP for all wells at 1930 and stopped all except hedgehog and en bilateral (exchanged AP).

    04/02/2015

    Exchanged the AP for the two Terebratalia wells, I’ll let them develop longer.

    Stopped at 1500 and did ethanol washes. Let overnight in 70% glycerol.

    Mounting and pictures.

    Cloning more segmentation genes 


    Warning: preg_match_all(): Compilation failed: invalid range in character class at offset 7 in /home/customer/www/phd.organelas.com/public_html/wp-content/themes/p2/inc/mentions.php on line 77

    I selected alternate primers for getting longer fragments and improving the quality of Novocrania in situs.

    Nano ptc2, wnt1, smo1, smo2, fgf8, Mmem wnt4

    2015-01-20 11.02.32

    wnt1 did not work again, bad ptc2 again, smo1 and smo2 weakly worked, fgf8 worked, Mmem wnt4 not… Re-run Nano ptc2 with different primers:

    2015-01-20 17.51.33

    Combination of primers 3F and 2R (395 bp fragment) was the only one that worked. Transformed:

    2015-01-23 17.16.01

    T7
    Na wnt5 BV352
    Na wnt5 BV353
    Na smo2 BV354
    Na fgf8 BV355
    Na fgf8 BV356
    Na ptc2 BV357
    Na ptc2 BV358
