Simultaneous detection of endogenous lectins and their binding capacity at the single-cell level--a technical note

Folia Biol (Praha). 1999;45(4):157-62.

Abstract

Endogenous lectins are proteins/glycoproteins which selectively recognize distinct saccharide ligands and are different from immunoglobulins and carbohydrate-utilizing enzymes. Expression of these molecules can be detected immunohistochemically using nonblocking monoclonal antibodies (A1D6: anti-galectin-3, MR-15-2-2: anti-175 kD mannose receptor). Alternatively, biotinylated (neo)glycoconjugates which are recognized by a studied lectin can be employed as convenient probes to demonstrate specific binding of sugar epitopes by carbohydrate recognition domains (CRD) of endogenous lectins. In this study, we describe a new procedure for immunocytochemical visualization of the expression of endogenous lectins and glycochemical visualization of the reactivity of carbohydrate recognition domain(s), performed simultaneously at the single-cell level.
