Spindle Angle Measurements
Authors:  Julien Cau, Nathalie Morin and Guillaume Bompard, date: 10/05/2013, view: 10516, Q&A: 0
Spindle angles measures derive from the measures of spindle poles positions that were taken from fixed and immunostained adherent cells. To determine spindle angles (α), z-stack images of metaphasic cells immunostained with anti γ-tubulin (spindle ...
