Protocol: Hyphal Tip Growth The null hypothesis is that mycalolide B lead not have an effect on fungous blossom growing and nuclear position. The alternative hypothesis is that mycalolide B leave have an effect on fungal rear festering and nuclear position. 1. Take off the tape and adopt a dislocate from petri dish that has an agar cushion that is smooth, devil-dimensional and no bubbles. 2. For the control, add 25 Âµl growth strength on hyphae with a Gilson pipette and yellow superlative and crown with a slip over it. Take note of the beat for separately swoop preparation. 3. Set up Kohler and observe the example on the slide with 10x neutral lens past choke to 40x objective lens, scourge from BF to fluorescence. 4. Once in focus draw up the ocular micrometer to be adjacent to the magnetic core to larn the position of the nuclei during growth. 5. Using the ocular micrometer, invoice and recruit the outer space the nucleus moves in 5 chip intervals. Do it with 3 unalike nuclei on champion slide prep and then throw away to another slide. 6. take observations for to each oneness nuclei and note the position, is it the similar distance or does it as well move forward. Calculate the fixedness also using s=distance/time. Make a add-in such as the one below and do one for each hyphal malarkey and for two different slides.
circuit card 1: Nuclear bit with Growth Medium (Slide 1) Time( momentutes)| outdistance (um)| Speed (um/ hour)| | 1| 2| 3| 1| 2| 3| 5 min| | | | | | | 10 min| | | | | | | 15 min | | | | | | | 20 min| | | | | | | 7. Aft er observing nuclei, switch back to BF and s! et up the ocular micrometer to be adjacent to fungal tip to determine fungal growth tip. 8. Using the ocular micrometer, measure and record the distance the tip grows in 5 secondment intervals. Do this with 3 different hyphal tips on one slide prep and then switch to another slide. 9. Record observations for each hyphal tip in table such as the one below but do one for each hyphal tip and for two different slides.
