Sialic acid (closed square), galactose (open diamond), GlcNAc (closed circle) and mannose (open square).

n.d., not detected.

^aThe purified phAT, rhAT-Manα, rhAT-Manβ, rhAT-Comα and rhAT-Comβ were employed as samples.

^bMolar ratios calculated versus GlcNAc composition.

^cMol sugar/oligosaccharide chain.

^dSchematic of the major oligosaccharide structures detected by MALDI-TOF MS are described above.
