An ELISA for grancalcin, a novel cytosolic calcium-binding protein present in leukocytes

Research output: Contribution to journalArticle


Grancalcin is a newly discovered cytosolic calcium-binding protein, belonging to the group of EF-hand proteins. Grancalcin is specifically associated with cells originating in the bone marrow. Grancalcin binds reversibly to secretory vesicles and plasma membranes in human neutrophils and might therefore play a role in the regulation of vesicle/granule exocytosis. We describe here the production of recombinant grancalcin, the generation of antibodies to the protein and the development of a specific, accurate and sensitive ELISA for the detection of human leukocytic grancalcin. This ELISA may be useful for monitoring leukocyte infiltration into tissues.
