Dear researchers,
Can anyone help me to identify these odd mammary glands in Ornithorynchus anaticus ?
I struggle to understand its mecanism :
The secretion from all these flat lobes have a pore, or is it the central canal that erupt from the the skin ?
Is it compound tubules or acinii in nature ? Or just tubules that radiated around a canal ?
I really want to compare this gland structure to Eutherian mammals.
Thank you very much !

Answer
Although it has mammary glands, it lacks nipples; milk is released through the pores of the skin. The female has grooves in the abdomen that form rafts of milk that allow the young to lick her. I don't know how dense the milk is, I suppose it is to avoid spreading before the baby can lick it. It is like the case of the cetaceans that the young do not breastfeed due to the morphological constitution of their mouths, however the milk is so rich in fat and dense that when the mother releases it, it takes time for the baby to take it before it is released. dilute in water.

Is there any way in Europe to get a small amount of frozen citrate plasma (several microliters should be enough) of platypus and echidna from Australia?
The research would involve cross-check reaction of some monotreme plasma proteins on antibodies against human plasma proteins by western-blotting.
If anyone has an access to the animals and knows how to organize such matter I would be grateful for personal contact.

I know this is now quite old, but you could try Frank Grutzner at the University of Adelaide, or Paul Waters at University of NSW (I think). Also, Kathy Belov.

Hello, I am working with AFM and I need to deposit different polymers on ultra flat stripped gold chips on silicon wafer. I would like to purchase the ultra flat stripped gold from platypus
I know these chips are meant for one use only, but there is someone aware of a good cleaning procedure I could use to remove the polymer and the possible contaminations and reuse the chip more than once?
Thank you very much for your help.

Answer
You can try to dissolve your polymer film with appropriate organic solvent and deionized water rinse with subsequently treatment in oxygen plasma.
