The availability of tick in vitro cell culture systems has facilitated many aspects of tick research, including proteomics. However, certain cell lines have shown a tissue-specific response to infection. Thus, a more thorough characterization of tick cell lines is necessary.

Journal of the American Society for Mass Spectrometry, 18(2), 201-207 (2006-10-28)
Development of a quantification method based on isotopic variants of O-methyl isourea (OMIU) in conjunction with reversed-phase (RP) liquid chromatography (LC) electrospray mass spectrometry is described for determining the relative quantification of tau-related peptides Ac-VQIVXK-NH2. Extracted ion chromatograms of the

Lysine epsilon-amino groups of human factor H were selectively converted to guanidino groups by treatment with 0.1 M O-methylisourea at pH 10.4. Guanidination resulted in a dose-dependent decrease in the capacity of the regulatory protein to accelerate decay dissociation of

The effect of modification of amino groups on RTX-III induced lethality in mice has been studied. The toxicity was not affected by guanidination of one or two lysine residues with O-methylisourea, but guanidination of three or four lysine residues decreased
