Honey bee colonies maintain viable queens in part through communication with Queen Mandibular Pheromone (QMP), a mixture that signals the queen's presence and reproductive quality to workers. In turn, workers are thought to provide retinue queen care

Honey bees (Apis mellifera) collect and store both honey and pollen in preserved forms. Pollen storage involves the addition of honey or nectar and oral secretions to pollen granules. It is controversial whether the duration of pollen storage alters

This protocol quantifies cysteine residues from small amounts of pollen (10 mg) after phenylisothiocyanate (PITC) derivatization (adapted from Manneberg et al 1995). Quantification of cysteine by other methods is difficult because of its instability

This protocol quantifies total lipid contents of pollen through colorimetric oxidation of lipids by chromic acid (adapted from Amenta, 1970). Small pollen samples (10 mg) are fractured by cell homogenization and lipids are extracted by Folch extracti

This protocol uses FAME (Fatty Acid Methyl Esterification) techniques adapted from Seppanen-Laasko et al., 2002 to quantify fatty acid contents in small samples (10 mg) of anther pollen, corbicular pollen, or stored pollen. Pollen is initially fractu
