The depolymerizing effect of the colchicine solution on MTs was established using HeLa cells and flow cytometry to detect mitotic arrest. |
For low concentrations of added BSA the MTs form a nematic, whereas at higher concentrations the rectangular bundle phase is observed. |
Note that the acentrosomal spindle pole completely lacks astral MTs and is associated with much less ER than the centrosome-containing pole. |
Then came the period of rhyolitic flows, the centers of volcanic activity being as before Mts. |
Experimental electron micrographs show that, upon rapid disassembly of MTs, the protofilaments peel off and curl. |
Many of the skulls had been trepanned, and these are brought into direct association with the full-blood Berbers of the Aures Mts. |
