Fig. 6From: An optimum study on the laser scanning confocal microscopy techniques for BiFC assay using plant protoplastThe correlation between inner diameter of pipette tips and protoplast intactness. A The broken ratio of protoplasts decreased when protoplast samples were pipetted using tips with cut ends. B The inner diameter of different tip ends. The broken ratio of protoplasts was calculated using the equation: broken protoplasts/total protoplasts. Protoplast samples were pipetted at a speed of 2–3 s per pipetting action. The test was repeated three timesBack to article page
