Reviewed in references 29 and 31. Type 1 precursor has β-1,3 linkage, found in Lea, Led, and Leb; type 2 precursor has β-1,4 linkage, found in H type 2, Lex, and Ley.
Glc, glucose; R, polyacrylamide with or without biotin (-PAA-biotin or -PAA, respectively); Fuc, fucose; Gal, galactose; GlcNAc, N-acetylglucosamine; Lac, lactose; GalNAc, N-acetylgalactosamine.
0, no binding; (+), weak binding; + to ++++, lower to higher strength of binding.
—, not a terminal moiety.
