title: Hop cone with lupulin glands removed 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 September 2011. 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 lupulin glands.
