<p class="jove_step">Collagenase Preparation</p>
<ol>
<li>Weigh out the collagenase into a 50 ml conical and add <strong>isolation buffer</strong> to make the final concentration, as indicated in the table below. Dissolve the collagenase by vortexing.<br /><br /><br />(12 mice + 2 extra mice = 14 mice x 5 ml/mouse = 70 ml total collagenase solution)<br /><br /><br />(70 ml x 0.5 mg/ml or 0.3 mg/ml = 35 mg or 21 mg of collagenase P total)<br /><br /><br />
