<p>MALDI MS peak analysis for ovine Candidate 7500 identified as sSgII-70.</p>

Analysis based on C-terminal truncation and water losses. Masses are for the native 70mer polypeptide sSgII-70 down to a 60mer (with predictions generated by Expasy Compute pI/Mw [14] and double-checked via an MS/MS fragment ion calculator: see S3 File). A mean deviation of m/z 2.66 is delivered at a mean error (i.e., difference as a percentage of match) of 0.035%; seven integer or next-integer matches (58%); ∑Observed (n = 12) 91120/∑Calculated Matches 91113 x100 = 100.01%; and chi-squared P = 0.024, significant (S3 Table 5 in S3 File). An extended version of Table 1 is provided as S3 Table 1 in S3 File.
