This next field season I will be collecting both blood and feather samples and I wondered how best to store the samples. The blood samples will be used for microsatellite and/or SNP analysis. The feather samples will be used for genetic sexing and/or microsatellite analysis.
Feathers: can these be stored in envelopes at "room" temperature? I've seen mixed answers in the literature. They are plucked feathers and so may have a bit of blood or tissue at the tip. If they are used for microsatellite analysis, I want to ensure this DNA is not degraded. I will be storing them frozen at my field site, but our partners at other sites may not have access to freezers.
Blood: we will be collecting blood into capillary tubes. I have a few Whatman FTA cards, but not enough. So I'm planning to freeze the blood in the capillary tubes. Are there better options than this? I'm planning to use non-heparinized tubes. Out of curiosity, has anyone used blood from FTA cards for microsatellite or SNP analysis? Can I expect sufficient DNA quantity and quality? Bird DNA is nucleated, so I should get more bang for my buck (volume-wise).
I appreciate your help!
