Isolectin GS-IB4 From Griffonia simplicifolia, Alexa Fluor™ 488 Conjugate (Invitrogen™)

Isolectin GS-IB4 is a 114,000-dalton glycoprotein that is part of a family of five tetrameric type I isolectins (IA4, IA3B, IA2B2, IAB3, and IB4) isolated from the seeds of the tropical African legume Griffonia simplicifolia. The A subunit prefers N-acetyl-D-galactosamine end groups while the B subunit is selective for terminal a-D-galactosyl residues. The green fluorescent Alexa Fluor® 488 isolectin GS-IB4 conjugate can be used in fluorescence microscopy or flow cytometry.

Lectin PHA-L From Phaseolus vulgaris (red kidney bean), Alexa Fluor™ 594 Conjugate (Invitrogen™)

Lectin phytohemagglutinin-L (PHA-L) is strongly inhibited by N-acetylglucosamine β(1-2) mannopyranosyl residues.[ALTREF PN29369] This lectin has been shown to agglutinate leukocytes and induce mitogenic activity in T-lymphocytes[ALTREF PN29369,PN29368] and has also been used as an anterograde tracer for the study of neuronal pathways.[ALTREF PN20284]

Concanavalin A, succinylated, Alexa Fluor™ 488 Conjugate (Invitrogen™)

This green-fluorescent Alexa Fluor 488 conjugate of succinylated concanavalin A (Con A) selectively binds to α-mannopyranosyl and α-glucopyranosyl residues. In acidic solutions (pH 4.5—5.6), Con A exists as a dimer with molecular weight of approximately 52,000 daltons; above pH 7, it is primarily a tetramer with a molecular weight of 104,000 daltons. Succinylation of Con A prevents tetramer formation, thus greatly reducing the lectin's agglutination activity but not its reactivity with glucose and mannose residues.
