(a) Negative ion ATD profile (unsmoothed) of Man4GlcNAc2 (15, 18, 21, [M+H PO ]− ions) from gp120. (b) ATDs of the diagnostic 6-antenna-specific fragment ions from Man4GlcNAc2 from gp120 (“Mean” smoothing algorithm from MassLynx, window size = 2, number of smooths = 2). Ions are identified as in Figure 2.
