CD1a Information for Pathologists


CD1a is a T cell surface antigen found on subsets of normal T cells. It is important in antigen presentation to dendritic cells, particularly glycolipids and lipopeptide antigens that traffic through early endocytic pathways. CD1a is also referred to as Leu6.

Common Uses By Pathologists:

CD1a immunostaining is used to diagnose Langerhans cell histiocytosis and to exclude other entities that are CD1a negative. It is also a useful means of identifying Langerhans cells in inflammatory or neoplastic disorders.

Limitations and Warranty

This antibody is manufactured in accordance with clinical good manufacturing practices in an ISO13485:2016 certified production facility. It is intended for multiple uses including in vitro diagnostic use and research use only applications. Please see vial label for expiration date. We strive to always deliver antibodies with a shelf life of at least two years.
