in situ Hybridization!

Molly and super special guest Dr. Elena Kramer, Professor of Organismic & Evolutionary Biology at Harvard University, perform an in situ hybridization to detect gene expression in a columbine flower bud.

    It's uncanny how identical your lab looks to my old lab when I was at the University of Missouri! And that was some mighty fine in situ work you did there.

    This is a super cool video! I am interested in whole mouth in situ hybridisation and currently isolating H4 gene for my plant of interest. I've been doing some research about how different ISH and WMISH are from each other and I didn't understand what are the differences in practical level. I would be so happy if you can give me a hand!

    This topic is not under my expertise. But because the several solutions, it seems this kind of experiment is very laborious. Congratulations for the scientific efforts!

    You are absolutely right, it is an *intensely* laborious 2-3 days-long experiment! Very disheartening when it doesn't work because you have to start from scratch, but SO satisfying when you finally get results!

    We use a Zeiss Axioimager & their Zen Blue software - we often counterstain our in situs with calcofluor white to get better contrast on our cell walls, so in that case we overlay the brightfield image (to visualize the probe) with the fluorescent image that detects the calcofluor (and helps the cells that don't have probe show up better in the final image)

    Can you please do a video on the design process of this experiment? How did you design the rna probe and antibody? Is there a simple online tool where I can design a tool and have a company manufacture it for me?

    Great idea, I would love to make a video about this one day! In the meantime, here is some info: Luckily you don't need to design the antibody - we use the commonly available anti-DIG antibody, so you just need to incorporate DIG-labeled NTPs into your probe during transcription. You can amplify your probe fragment from cDNA - you just want to make sure it's in a specific region of your gene of interest so that you don't detect closely related genes. We usually design our probes with one end in the UTR to ensure specificity, but definitely do an alignment with other members of the gene family to check where the conserved regions are. Here is our lab's protocol - this is a slightly older version, again I just amplify from cDNA and use that fragment directly in the topo reaction. There might be a service that would make probes for you but I imagine it would be very pricey! kramerlab.oeb.harvard.edu/files/kramerlab/files/in_situ_protocol_corrected-2.pdf?m=1430323911

    @@milesgiehtbrock8510 we don't have stable transgenics in Aquilegia yet so I can only use VIGS (Virus induced gene silencing) to target genes of interest, unfortunately. For VIGS we usually use the same target fragment as our in situ hybridizations.
