* Approximate absorption (Abs) and fluorescence emission (Em) maxima, in nm, for conjugates. † Lectin sources: Concanavalin A (Con A) isolated from Canavalia ensiformis (jack bean); Wheat Germ Agglutinin (WGA) isolated from Triticum vulgaris; IB4 isolated from Griffonia simplicifolia (an African legume); GS-II isolated from Griffonia simplicifolia; PHA-L isolated from Phaseolus vulgaris (red kidney bean); HPA isolated from Helix pomatia (edible snail); SBA isolated from Glycine max (soybean); PNA isolated from Arachis hypogaea (peanut). ‡ Succinylated Alexa Fluor 488 concanavalin A is also available, C21401. § The properties and applications of Qdot nanocrystal conjugates are described in Qdot Nanocrystals—Section 6.6. NA = Not applicable.

For researchers interested in testing our fluorescent WGA conjugates in their application, we also offer a Wheat Germ Agglutinin Stain Sampler Kit (W7024), which contains 1 mg quantities each of WGA conjugates of the Alexa Fluor 350, Oregon Green 488, tetramethylrhodamine and Texas Red-X dyes.
