Optimization of carbamylation conditions and study on the effects on the product ions of carbamylation and dual modification of the peptide by Q-TOF MS.

Cheng Guo et al.

European journal of mass spectrometry (Chichester, England), 24(5), 384-396 (2018-07-26)

Modified peptides fragmented by collision-induced dissociation can offer additional sequence information, which is beneficial for the de novo sequencing of peptides. Here, the model peptide VQGESNDLK was carbamylated. The optimal conditions were as follows: temperature of 90℃, pH of 7

Tissue-specific signatures in tick cell line MS profiles.

Dmitry S Loginov et al.

Parasites & vectors, 12(1), 212-212 (2019-05-08)

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.

Lysine residues, but not carbohydrates, are required for the regulatory function of H on the amplification C3 convertase of complement.

M H Jouvin et al.

Journal of immunology (Baltimore, Md. : 1950), 133(6), 3250-3254 (1984-12-01)

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

Relative quantification of tau-related peptides using guanidino-labeling derivatization (GLaD) with online-LC on a hybrid ion trap (IT) time-of-flight (ToF) mass spectrometer.

Jessica Z Bereszczak et al.

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

Heat stability of milk: influence of modification of lysine and arginine on the heat stability-pH profile.

S I Shalabi et al.

The Journal of dairy research, 49(4), 607-617 (1982-11-01)

Several dicarbonyl compounds (glyoxal, substituted glyoxals, diacetyl and 1, 2-cyclohexanedione) had a marked stabilizing effect on the heat stability of milk, especially in the presence of urea. These reagents are believed to modify arginine more or less specifically suggesting an
