Glycosylation peak height. Six dodecamers as individual trimers. N peak is counted full with each trimer. Same MO as many previous posts: y axis is grayscale 0-255, this peak is almost always prominent, one either side of the N term peak and present on most SP-D dodecamers (exceptions being when glycosylation is not present). Check out value from the first four dodecamers, here.
Six dodecamers: SP-D – tiny peak height (peak two, in each trimer, located (about half the time) on the down-slope of the N termini junction peak (peak 1) and just before the glycosylation peak (peak 6). This is detected by many of the signal processing programs, at this point it is an unreported peak in SP-D. Means, SD, median, etc listed below for each individual dodecamer of this set of 6, and as a group of 6. MO is the same as reporting on other peak widths-heights-and valleys. First set of 4 dodecamers, 134.7+/19.5 (grayscale 0-255) and all data for that set is here.
