For posterity: As far as I can tell so far, when receptors are expressed constitutively at decent levels, ligands are usually limiting. Receptors that are conditionally expressed are usually limiting. Haven't figured out how hard 'limiting' applies in either case.
This is from conversations rather than primary research, so #CaveatEmptor.

If you want to build a career in biotech, should you get a PhD after college or join a company directly (as a Research Associate/RA, usually)?
There's no single answer, but I have the conversation often enough that I thought I'd share some pros/cons... (1/n)
First, see this thread about different types of biopharma companies. For reasons I'll get into, I think early stage (probably founder led) biotech is your best bet unless you still want to do PhD later.
(PS if you want to be a professor, it's 💯 PhD) 2/n
PhD will give you more options.
Some companies (incl. @GordianBio) will help you grow from RA to Scientist role (and beyond). But many, esp larger, companies have a glass ceiling if you don't have a PhD. Even if you pick one w/o glass ceiling, you'll be worse off it if fails. 3/n
All these points resonate, for early stage biotech at least. @erlichya touches on this, but I think worth separating "industry" into different clusters that will feel quite different to someone coming from academia (still oversimplified, of course):
Pharma (eg Pfizer) vs biotech:
You wear fewer hats, see less of the company but company as a whole spans wider range of expertise, fewer changes in direction, often higher income but no chance of getting rich. Both have job insecurity: pharma doesn't go die but programs do.
Clinical vs R&D stage biotech:
Clinical may still have R&D but it's no longer the biggest driver of success vs failure. Assay validation/rigor > assay development/invention. Clinical can feel more like pharma, but with more urgency/stakes: one program = life or death of co.
#SciTwitter After a lot of research and asking around, I'm making the lab equipment recommendations 🧵 I wish I'd had 2 months ago. RT/share with a #newPI or startup 🔬⚗️🛒
Note, much of the equipment hasn't arrived yet, will add comments after actual use.

Less clear, many viable options. We ended up getting a split of PHC MDF -30 (recommended as quieter) and much cheaper Corepoint Scientific/@VWR, will see which we prefer. Thermo hasn't failed #MBCbiolabs, but $$$ and several people said poor customer support.
As with all experiments, I expect that some of these will disappear and that others will be a central part of science in ten years.
But them happening at all is enough to renew a conversation about how science is funded and conducted.
🦸🏽 While I've been doing most of the tweeting, the Longevity Apprentices @LNuzhna@kush__sharma@edmarferreira & Tara Mei are the real heroes for running the operations.
This has been a great Apprenticeship project, merging action and exposure to research martinborchjensen.com/apprenticeship
🚅 The review + awards process was fairly smooth, thanks in part to @kush__sharma's custom reviewer UI. Several reviewers told us unprompted that it was their best review experience ever; the UI took 2 wks to make, so there's low hanging fruit for other agencies in that area.
Thrilled to announce the Longevity #Impetus Grants, $21M+ towards basic research that could accelerate our understanding and control of human aging.
We welcome proposals from researchers in- and outside the #Aging field. Please share!
Impetus Grants are $10k-500k (w max 10% overhead). Smaller requests favored, to support more projects. No project period and no strings attached. Scientists at non-profits worldwide can apply with ideas that shift perspectives & capabilities in #Aging research, starting Sep 13th.
Inspiration came from @tylercowen & @patrickc's #COVID19 Fast Grants. Their team made funding decisions in 2 weeks, and the grants have already led to both discoveries and better tools for #testing.
If it's feasible to fund science this way, shouldn't we? future.a16z.com/what-we-learne…
