General description

HPLC Plus grade water is useful for the UHPLC (Ultra-High Pressure Liquid Chromatography) gradient elution and HPLC studies.

Application

Water has been used in the following studies:
  • To prepare the diluted hydrochloric acid solutions required for the preparation of standard solutions of amino acid.
  • In the sample extraction step during the gas chromatography mass spectrometric (GC-MS) analysis of free (FAA) and combined amino acids (CAA) in aerosol samples.
  • Preparation of tryptic digests from the standard protein samples and milk digests from milk samples.
  • Preparation of C60-aminopropylsilica.

The analysis of amino acids by gas chromatography mass spectrometry (GC-MS) after their derivatization with N-(t-butyldimethylsilyl)-N-methyltrifluoroacetamide was investigated as an alternative approach for the determination of free (FAA) and combined amino acids (CAA) in aerosols. This technique showed excellent linearity

Phosphorylation of proteins is an important cellular regulatory process. The analysis of protein phosphorylation is challenging due to the high dynamic range and low abundance natures of phosphorylated species. Mass spectrometry (MS) of phosphopeptides obtained from tryptic protein digests is

Linear ubiquitination is a newly discovered posttranslational modification that is currently restricted to a small number of known protein substrates. The linear ubiquitination assembly complex (LUBAC), consisting of HOIL-1L, HOIP, and Sharpin, has been reported to activate NF-κB-mediated transcription in

Oseltamivir-resistant H1N1 influenza viruses carrying the H275Y neuraminidase mutation predominated worldwide during the 2007-2009 seasons. Although several neuraminidase substitutions were found to be necessary to counteract the adverse effects of H275Y, the order and impact of evolutionary events involved remain

Closing gaps in draft genome assemblies can be costly and time-consuming, and published genomes are therefore often left 'unfinished.' Here we show that genome-wide chromosome conformation capture (3C) data can be used to overcome these limitations, and present a computational
