title: Hop lupulin glands from Apollo (Yakima, USA collection)
organism: Humulus lupulus
description: Lupulin glands were isolated from mature female inflorescences (cones) of the high-alpha acid hop cultivar 'Apollo' collected in Yakima, USA in August 2009. Glands were removed from dissected cone bracts and bracteoles by stirring in liquid nitrogen, followed by filtration through a 1 mm mesh screen to remove cone materials.
