Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is: 1.0 microgram per one million cells in 100 microliter volume or 100 microliter whole blood. Immunohistochemistry-frozen/paraffin. Western Blot was reported in scientific literature. It is recommended that the reagent be titrated for optimal performance for each application.

Background
CD74 is a type II transmembrane glycoprotein, also known as MHC Class II associated invariant chain, invariant chain, Ii, MHC class II chaperone, or MIF receptor. CD74 exists in 4 isoforms with the molecular sizes 33, 35, 41, and 43 kDa depending on genetic splicing. CD74 is primarily expressed on antigen presenting cells, including B cells, monocytes/macrophages, dendritic cells, and Langerhans cells. It is also expressed by activated T cells, activated endothelial and epithelial cells as well as the carcinomas of lung, renal, gastric and thymic origin. The primary function of CD74 is for intracellular sorting of the MHC class II molecules, regulation of loading exogenous peptides onto MHC class II. It is also involved in the modulation of B cell differentiation and positive selection of CD4+ T cells. It has been reported that CD74 binds MIF (macrophage migration inhibitory factory) and signaling through CD44 to regulate innate and adaptive immunity, and that the H. pylori infection is through urease B binding CD74 on gastric epithelial cells and inducing cell activation.

CD74 - a central player in antigen presentation by MHC class II Cluster of differentiation 74 (CD74) is an important integral membrane protein that serves as a chaperone for MHC class II molecules. CD74, also known as the invariant chain or Ii, is needed for the proper folding and trafficking of MHC class II in... Read full blog post.
