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.

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

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

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
