Wet-Lab Protocol

22.05.2018
Opening pollen with Trypsin
-Resuspending 20µg Trypsin in 200 µl of water
-Splitting solution in 4 eppis with 50 µl each => approxamittly 5 µg of Trypsin in each eppi
-5000 U/mg=Proportionalitycalculation
-50mg of pollenmaterial
-3 active Trypsin-eppis (incubating at 30 °C for 15 minutes)
-Approxamittly 15 µg of Trypsin available
Calculating units:
-1 mg= 5000 U
-1 solution: 15 µg= 0.015 mg= 75 U=> 1:3.3
-2 solutions: 7.5 µg=0.0075 mg= 37 U=> 1:6.6
-3 solutions: 5 µg=0.005 mg= 25 U => 1:10
-Proportionality=weight Trypsin : weight pollen
-Add 50 µg of pollen to 10µl Trypsin and 120µl Ammoniumhydrocarbonate
-Incubating at 37°C over night
=> analyzed with light microscopy on 23.05.: did not work

-Microscopy Birchpollen (100x)
-Microscopy Birchpollen (400x)
-Microscopy Willowpollen (100x)
-Microscopy Willowpollen (400x)
-Microscopy Sprucepollen (100x)
-Microscopy Sprucepollen (400x)

Extraction of pollen
-Putting male infructescence into a electrostaticly loaded plastic tube
-Vortexing tube => pollen stick to walls of the tube
-Extracting pollen
-Analyzing with light microscopy if only one type of pollen is in each tube

23.05.2018

Electromicroscopy

-Prepare samples
-> 1: birchpollen
-> 2: Spruce-trypsin supernatant
-> 3: Spruce-trypsin sediment
-> 4: SPruce and spruce ribolysed

-Dried in etikator
-Evaporated with gold
-DNA-extraction pollen
-50 mg in rybolyser tubes
-Constant shaking in rybolyser (6500*2*30*30)
-> centrifugate for 10 min (1100 rpm)

Results:
-Two layers:
-> over the upper one: white shroud
-> light-brown layer of pollen: abstraction with chemical droppper
-> 400µl lysebuffer, centrifugate 1 min (11000 rpm)
-> DNA-extraction: machery nagel plant NUcleo spin III Kit
