That does not make B12 useless
subcutaneous or intramuscular injection
It's about building good lab habits that respect the science and the investment you've made in your research materials
Notably, controlled fluid flow introduces sustained perfusion and physiologically relevant shear forces, both of which modulate cellular behaviour and allow for a more accurate assessment of nanoparticle transport, distribution and cellular uptake than static in vitro models [175, 176]
