Frog Fish and Chick people: what protocol do you use to remove yolk?

A protocol question from Prof Malgorzata Kloc:

“For many years I have used Freon to remove yolk from Xenopus egg/oocyte extracts.
For some time, Freon is not allowed in the lab. Is there any other method(s) to remove yolk?”

Please post you answers here. You can also contact Malgosia directly:
