Abstract
Macherey-Nagel Nucleospin 96 Food protocol for bee pollen
Protocol materials
Lysis Buffer CFMacherey-NagalCatalog #740946
Proteinase KMacherey-NagalCatalog #740506
Binding Buffer C4Macherey-NagalCatalog #740366.250
Elution Buffer CEMacherey-Nagal
Wash Buffer CQWMacherey-NagalCatalog #740313.125
Wash Buffer C5Macherey-NagalCatalog #740931
UV sterilize supplies for 2 96 well plates worth of extractions: 4 50mL centrifuge tubes, 2 15mL centrifuge tubes, zirconia beads, 2 96 deep well plates and clear strip caps, 2 s-blocks, 2 96 well elution plates, 14 1000uL tip boxes, 2 200uL tip boxes, 2 10uL tip boxes, 6 reagent troughs, and 6 96 well microplates
Aliquot Lysis Buffer CFMacherey-NagalCatalog #740946 into sterile centrifuge tube and warm in 65 °C water bath. You will need to aliquot 30 mL per 1/2 plate (48 samples)
Add 540 µL Proteinase KMacherey-NagalCatalog #740506 to each warmed 30 mL
Lysis Buffer CFMacherey-NagalCatalog #740946 aliquot and invert gently to mix
Add 560 µL Lysis Buffer CFMacherey-NagalCatalog #740946 + Proteinase KMacherey-NagalCatalog #740506 solution to each sample
Note
Each sample will receive 550 µL Lysis Buffer CFMacherey-NagalCatalog #740946
and 10 µL Proteinase KMacherey-NagalCatalog #740506
Place in tissue lyser and run at 10 Hz for 00:01:00
Note
Make sure pollen ball is removed from bee leg after lysing. If still attached, repeat this step, increasing Hz if needed

Using sterile tweezers, remove bee leg, rinse with 200 proof ethanol, and place leg into labeled sterile microcentrifuge tube. Sterilize tweezers between each use with flame. Leave leg tubes open in fume hood until remaining ethanol has evaporated, then store at -80 °C
Note
If extracting pollen not attached to bee leg, skip steps 5-7
Add ~100 µL zirconia beads to each pollen sample
Place in tissue lyser and run at 24 Hz for 00:01:30 , rotate plates 180 degrees, and lyse again at24 Hz for 00:01:30

Place in 65 °C water bath for 00:30:00
Note
Incubation time may be increased up to overnight if extraction of DNA from pollen during lysis was not sufficient

35m
Transfer 300 µL of supernatant into 96 deep well plate
Note
Samples may be stored at -20 °C after this step
Add 300 µL (or equal volume) Binding Buffer C4Macherey-NagalCatalog #740366.250
and 300 µL (or equal volume) 200 proof ethanol
Note
Binding Buffer C4Macherey-NagalCatalog #740366.250 and ethanol may be combined ahead of time. Check note on reagent bottle. If already combined, add 600 µL Binding Buffer C4Macherey-NagalCatalog #740366.250 /EtOH solution. Binding Buffer C4Macherey-NagalCatalog #740366.250 with EtOH added may be stored at room temperature for up to 1 month
Safety information
Binding Buffer C4Macherey-NagalCatalog #740366.250 contains guanidine salt - do not mix with bleach
Vortex samples until thoroughly combined
Centrifuge 1500 x g for 00:00:30
Note
Do not centrifuge at a higher g-force or for a longer duration - this will precipitate out DNA
30s
Place food binding plate onto s-block and transfer sample to food binding plate. Seal with gas-permeable foil
Centrifuge 3220 x g, 00:09:00 , discard flowthrough

While centrifuging, aliquot out 12 mL per plate of Elution Buffer CEMacherey-Nagal and place in 70 °C water bath
Add 500 µL Wash Buffer CQWMacherey-NagalCatalog #740313.125 and seal
Safety information
Wash Buffer CQWMacherey-NagalCatalog #740313.125 contains guanidine salt - do not mix with bleach
Centrifuge 3220 x g, 00:04:00 , discard flowthrough
