An observation that magnetic particles are transported through organogel encouraged us to investigate its feasibility of liquid-phase displacement in DNA extraction using magnetic particles. Organogel for this study was prepared from a gelator, 12-hy

Human basic fetoprotein (BFP), found in fetal serum and tissue extracts as well as in extracts of various cancer tissues, has long been known as a marker protein for cancers; however, the primary sequence has not yet been reported. This paper describ

N- and C-terminal amino acid sequences of human epidermal growth factor receptor-2 (HER2), purified from breast cancer cell lines (SK-BR-3 and BT-474), were analyzed at the protein level using mass spectrometry. Two N-terminal peptides and one C-term

We describe here an optimization study of the sample preparation conditions for sensitive detection of peptides by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS). Among many factors in the conditions, we varied the percent a

This paper describes an improved method for the sequence analysis of Arg-containing glycopeptide by MALDI mass spectrometry (MS). The method uses amino group derivatization (4-aza-6-(2,6-dimethyl-1-piperidinyl)-5-oxohexanoic acid N-succinimidyl ester

Melanization is one of the major immune responses in arthropods. Prophenoloxidases (proPOs) catalyze the oxidation of mono- or o-diphenols, a reaction that is the key initial step of melanin formation. Well-characterized proPOs from crustaceans are s

Many eukaryotic proteins are blocked at the α-amino group of their N-terminal with various modifications, thereby making it difficult to determine their N-terminal sequence by protein sequencer. We propose a novel method for selectively isolating th

A novel method for selectively labeling and isolating N-terminal peptide from protein has been developed. An N(alpha)-amino group of protein was converted to a carbonyl group through transamination reaction and the resulting carbonyl group was modifi

We describe a mass spectrometric method for distinguishing between free and modified forms of the C-terminal carboxyl group of peptides and proteins, in combination with chemical approaches for the isolation of C-terminal peptides and site-specific d
