1-Fluoro-2,4,6-trimethylpyridinium tetrafluoroborate

Flow injection analysis of serum urea using urease covalently immobilized on 2-fluoro-1-methylpyridinium salt-activated fractogel and fluorescence detection.

D Narinesingh et al.

Analytical biochemistry, 188(2), 325-329 (1990-08-01)

Serum samples were analyzed for their urea content using fluorescence flow injection analysis incorporating an immobilized urease bioreactor and a gas permeable separator. The urease was immobilized under mild and facile conditions to a hydrophilic 2-fluoro-1-methylpyridinium-activated support. The ammonia released

2-hydrazino-1-methylpyridine: a highly sensitive derivatization reagent for oxosteroids in liquid chromatography-electrospray ionization-mass spectrometry.

Tatsuya Higashi et al.

Journal of chromatography. B, Analytical technologies in the biomedical and life sciences, 825(2), 214-222 (2005-10-11)

A derivatization reagent, 2-hydrazino-1-methylpyridine, was developed for the liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) of oxosteroids. The reagent quantitatively reacted with oxosteroids at 60 degrees C within 1h and the resulting derivatives of the mono-oxosteroids provided a 70-1600-fold higher sensitivity compared

Flow injection analysis of lactose using covalently immobilized beta-galactosidase, mutarotase, and glucose oxidase/peroxidase on a 2-fluoro-1-methylpyridinium salt-activated Fractogel support.

D Narinesingh et al.

Analytical biochemistry, 194(1), 16-24 (1991-04-01)

Milk samples were analyzed for their lactose content using flow injection analysis and incorporating immobilized beta-galactosidase or beta-galactosidase/mutarotase and glucose oxidase/peroxidase bioreactors. These enzymes were immobilized, under mild conditions, on to a 2-fluoro-1-methylpyridinium salt-activated Fractogel support. The use of a

Studies in C-terminal sequencing: new reagents for the synthesis of peptidylthiohydantoins.

N R Shenoy et al.

Journal of protein chemistry, 12(2), 195-205 (1993-04-01)

In previous studies aimed at the sequencing of peptides and proteins from the carboxy terminus, we have derivatized the C-terminus to a thiohydantoin using acetic anhydride and trimethylsilylisothiocyanate (TMS-ITC) and subsequently hydrolyzed it to form a shortened peptide capable of

Analysis of steroid estrogens in water using liquid chromatography/tandem mass spectrometry with chemical derivatizations.

Ying-Hsuan Lin et al.

Rapid communications in mass spectrometry : RCM, 21(13), 1973-1983 (2007-05-26)

Even in trace amounts, estrogens such as 17beta-estradiol (E2), estrone (E1), estriol (E3), and 17alpha-ethinyl estradiol (EE2) may have adverse effects on humans and the aquatic ecosystem. Therefore, it is essential to be able to measure trace amounts of steroid
