In Drosophila Robo3 guides axons independently of the canonical repellent, Slit. The authors' findings challenge current models moving the field deeper into understanding the nervous system development!  🪰🌟 doi.org/10.1016/j.yd...

Lower images show anti-Robo3 channel alone from the same embryos. In wild type embryos, endogenous Robo3 protein is detectable on longitudinal axons within the outer two-thirds of the neuropile. Robo3 protein is undetectable in embryos homozygous for the robo3 loss of function and deletion alleles.

Apologies for the missing Alt text
Fluorescent microscopy images of stage 16–17 Drosophila embryonic ventral nerve cords form wild type, mutant, and modified robo3 alleles, stained with anti-HRP (magenta; labels all axons) and anti-Robo3 (green) antibodies.

RRID:CVCL_D603 was used by the authors of the FEBS Letters paper "Glu592 of the axon guidance receptor ROBO3 mediates a pH‐dependent interaction with NELL2 ligand". We appreciate the author's support of reproducibility. #ReproducibleResearch #RRID

Then again I like all the Lethal Weapon movies, which got more bombastic and inanely over-the-top after the first movie, so maybe I should give it a chance

I will probably not watch Robo3 tho lol

There are no large-scale defects detectable with anti-HRP in the axon scaffold.
In homozygous slit2 null mutants, all axons collapse at the midline due to a complete lack of midline repulsion, but Robo3 protein is still localized properly to axons.

The authors included RRIDs in their in bioRxiv paper! RRIDs improve reproducibility in scientific research. #accelerateopenscience #BetterScience #OpenScience

www.twitch.tv/j3xrg beep bop boop bop... yup. Robo3 today. I"m playing some #teamfighttactics now, little #LeagueOfLegends ranked later, maybe arams? Then to end the night we shall plate up!
j3xrg - Twitch
I'm here for one thing and one thing only... suffering... Kidding. some Tft/LoL until we plate? Reminder 24 hr coming up friyay.

#Robo3 antibodies are crucial for detecting the Roundabout Guidance Receptor 3 protein & studying neuraldevelopment & #axonnavigation—but reliable #antibodies are in short supply.

IPI just released two anti-ROBO3s that might help.

These days I enjoy video essays on games in genres I don't play. I love hearing in depth about what makes these things interesting and important to people, even if I'm not going to spend the time.

Just go in knowing that yes, Robo3 is PG-13, but it's still dark af. It's free on tubi right now!
