Is CD44 degraded in lysosome together with hyaluronan after CD44 mediated endocytosis of hyaluronic acid?

Also when RHAMM binds hyaluronic acid, they get internalized, will RHAMM also be degraded? Or both CD44 and RHAMM will be transferred back to the cell membrane? Asking for breast cancer cell line...

What could be some reasons why unstimulated monocytes are getting activated?

Im doing PBMC isolation -> CD14+ enrichment using magnetic beads -> stimulation setup. My negative control is just cells in cRPMI but they seem to get activated over and over again.

Should we reduce the standard unit of length to 0.31951540592 meter ?

The reasoning behind this question is to align the ratios of the proton potential in energy per charge to the speed of light in distance per time. As these two dimensions appear to be related,...

Heavy metals do not never degradate! They can be absorbed.

Remember that also absorption is always an equilibrium proces! Thus a real 100 % absorption is never achieved.

Henrik Rasmus Andersen

Sorption is an equilibrium reaction. If you didn't reduce the concentration in water enough, use more sorbent or even better, use treatment in series of repeated treatment - or make a column of the sorbent to remove the metal completely.
