Application

Nerve cells accumulate certain FITC-labelled lectins, with much greater accumulation in nerves that are regnerating after traumatic damage. Uptake is seen with Con A and wheat germ agglutinin, but not agglutinins from Dolichos biflorus, peanut, Ulex europaeus, or soybean.

Physical form

lyophilized powder, containing phosphate buffer salts and NaCl

Cytofluorometric quantification of the accumulation of somatopetally transported fluoroisothiocyanate (FITC)-labelled wheat germ agglutinin (WGA) and Concanavalin A (Con A) were performed on sections of the mouse facial nucleus. The lectins were injected bilaterally in the snout region of six-week-old mice
