Fig. 2From: New simple and quick method to analyze serum variant transthyretins: direct MALDI method for the screening of hereditary transthyretin amyloidosisDetection of variant TTRs by using direct MALDI. a Mass peaks of TTRs in serum samples obtained by means of direct MALDI. Arrows point to variant TTR peaks. b Correlation between measured and theoretical mass shifts (y = 0.9937x + 0.0834; r2 = 0.9969)Back to article page
