    Meara in situ for RNA binding proteins 

    Starting in situ with mixed stages of Meara. 15 min protk.

    ago a ago b boule bruno a
    gus a mago orb2 staufen


    Added probes.


    First day of washes. Some small juveniles have ripped tissues. I guess the 15min protk is too much for them, the rest looks ok.


    Regular 5 PBT and 5 PTw antibody washes. Kept rocking in cold room.


    Developing day. Stopped argonaute after ~3h, they were becoming too dark. Bruno, Staufen are clearly there. Boule is weaker, but something. The rest there is nothing. Putting new AP in cold room.


    In addition to Argonaute I also stopped Bruno, Staufen and Orb2 before going to the collection trip. The rest are developing overnight a bit more (also included Orb2 to develop overnight.

    Meara miniprep check 

    Ran a PCR to check the miniprep swap I did last time. I selected 2 sequences that will be used for in situ probes and ran a PCR with primers from both genes (boule and gus a). The correct gene should be amplified by its primer pairs and confirm the identity of the miniprep. As it can be seen in the gel I did indeed swap the labels of the miniprep, so BV226 is gus a and BV229 is boule.

    Cloning of Meara RNA binding proteins 

    Initial cloning of Meara RNA binding proteins. Selection: ago a, ago b, ago c, boule, bru a, bru b, gus a, mago, mex3, orb2, stau.


    Only 3 genes had visible bands: boule, gus a, and stau:

    2013-03-10 17.12.53

    Ligated these overnight.


    Transformation and plated the genes.


    Colony PCR with 6 colonies from each:

    2013-03-12 16.58.53


    Put colonies to grow.

    boule c1 BV226 BV229
    boule c2 BV227 BV230
    boule c3 BV228 BV231
    gus a c1 BV229 BV226
    gus a c2 BV230 BV227
    gus a c3 BV231 BV228
    stau c1 BV232
    stau c2 BV233
    stau c3 BV234


    Extracted plasmid and did sequencing PCR for all using T7 primer. Dropped tubes into sequencing facility.


    Checking sequences and they look good, but there is a problem! Minipreps BV226, 227, 228 aligned with gus a and not with boule!!! Check why…

    Checked in new primers for Meara RNA binding proteins. Let the cloning begin!

    Today Andi, Aina, and me went on the boat to collect Novocrania anomala and Meara stichopi.

    N. anomala was collected by dredging rocky bottom and looking for specimens attached to rocks and shells. Rocks were kept in a large box with sea water and transferred to S4 tanks with flowing sea water at Sars.

    M. stichopi was also collected by dredging, but on mud bottom. Around 20 specimens were captured in a new spot: 60°14.946 N, 05°08.481 O
