Immunofluorescent localization of beta2-microglobulin in the human kidney

Using antisera to human beta2-microglobulin and an immunofluorescent technique, beta2-microglobulin was found to be localized along tubular and glomerular basement membranes of renal bipsies studied. Since beta2-microglobulin is a subunit of HLA preparations, it may also serve as an indirect marker for the presence of HLA antigens in these structures.
