The correlations between relative reactivities of s-IgG and i-IgG glycans with lectins.

Correlations between lectins relative reactivity s-IgG vs. i-IgG	Spearman rank coefficient (r)
RCA-I vs. RCA-I	r = 0.226 p = 0.02
GLS-II vs. GLS-II	r = 0.440 p = 0.000005
GSL-II/RCA-I vs. GSL-II/RCA-I	r = 0.365 p = 0.0002
SNA vs. SNA	r = 0.421 p = 0.00001
MAA vs. MAA	r = 0.487 p = 0.000000
MAA/SNA vs. MAA/SNA	r = 0.449 p = 0.000003

Serum native IgG—s-IgG; serum IgG isolates—i-IgG. GSL-II: Griffonia simplicifolia lectin II, recognizing terminal GlcNAc; RCA-I: Ricinus communis agglutinin I, recognizing terminal Gal; MAA: Maackia amurensis agglutinin, recognizing sialic acid α2,3-linked; SNA: Sambucus nigra agglutinin, recognizing sialic acid α2,6-linked. A two-tailed p-value of less than 0.05 was considered as significant.
