摘要:
A determination method quantifies a specific protein or peptide contained in a trace amount with high accuracy and in a simple manner without the need of using any expensive reagent. A protein or peptide of interest can be quantified by LC/MS/MS by using, as an internal standard, a protein or peptide including an amino acid sequence having the reshuffling the binding order of amino acid residues in the amino acid sequence for the protein or peptide of interest.

摘要:
The production of RANKL may be inhibited by orally ingesting a milk-derived basic protein. Thus, a RANKL production inhibitor containing a milk-derived basic protein fraction as an active ingredient; a therapeutic agent for a metabolic bone disease and a therapeutic agent for an immune disease each containing the RANKL production inhibitor; and a food/beverage and a feed each containing a specified amount of the RANKL production inhibitor and being characterized by inhibiting the production of RANKL have a remarkable effect of inhibiting the production of RANKL, can be ingested on a daily basis, and exhibit high safety even when being ingested over a long period.

摘要:
Provided are: an agent for promoting growth hormone-secretion, containing a milk-derived basic protein fraction as an active ingredient, with the promotion of growth hormone-secretion being mediated by the promotion of secretion of ghrelin having an effect for promoting growth hormone-secretion; and a method of promoting the secretion of ghrelin by using a milk-derived basic protein fraction. The agent for promoting growth hormone-secretion may be ingested on a daily basis and is highly safe even with its ingestion for a long period.
