    Membranipora in situ Syt1a and Nanos 

    In situ with Membranipora for testing the newly fixed material with glutaraldehyde. I’m using 4 conditions and 2 genes:

    ProtK Time Gene Gene
    0.5x 10 min Syt1a Nanos
    0.5x 20 min Syt1a Nanos
    1x 20 min Syt1a Nanos
    2x 20 min Syt1a Nanos

    31/10/12

    Developing the in situ. Wells with nanos already showing the background all around with no difference from treatments. Synaptotagmin looks more promising, no background still. First well seems to have a slight purpleish regions, but others are plain white. Exchanged the AP twice and let it overnight in cold room.

    01/11/12

    Nanos is completely background. On syt1a I think there is signal in the last two treatments (1x and 2x). The lighter treatments seem to have some background. I exchanged the AP twice and will stop the reaction today.

    02/11/12

    It seems that synaptotagmin works.

    Membranipora in situ with new material 

    Starting an in situ with the newly fixed material of Membranipora. I took 200 µL from X, X, X, X days and mixed. Since samples were fixed with 3.7% PFA + 0.2% Gluta I am testing the time in proteinase K for 2 genes, Synaptotagmin and Nanos (a strong one and a known one), with 30s and 1:30s.

    30s 1m30s
    Mm gene Syt1a Syt1a
    Mm gene Nanos Nanos

    17/10/12

    Started developing at 11h30. By night a weak background began to appear in the shell.

    18/10/12

    Change AP at 10h. Background became stronger and apparently no real signal neither in syt or nos. Some larvae in the syt wells do not have much background. Crystals appeared in the afternoon… Kept developing at 4 °C.

    21/10/12

    Stopped developing.

    24/10/12

    Checked under microscope… only background it seems.

    More Membranipora genes: Mex3, Fez, PL10, FoxG, Syt1a, Syt1b 

    Set a PCR to clone: Mex3, Fez, PL10, FoxG, Syt1a, Syt1b

    02/04/12

    Bands with expected lengths. Purified DNA, set ligation reaction for 1h45 at RT, heatshock transformation and plated colonies with Xgal.

    03/04/12

    Plates were wetty, so colonies did not spread well… some were forming strings; but enough to pick. Picked white colonies for colony PCR:

    09/04/12

    Sequencing PCR and dropped in the SeqLab.
