Identification of salivary proteins at oil-water interfaces stabilized by lysozyme and beta-lactoglobulin.

In this research, we investigated the interaction occurring between oil-in-water emulsion droplets, stabilized by different emulsifiers, i.e. lysozyme and beta-lactoglobulin (beta-lg), and salivary proteins (SPs) with a molecular mass (M(r)) above about 10kDa.

Presence of cytosolic peroxiredoxin 2 in the erythrocyte membrane of patients with hereditary spherocytosis.

We studied 82 Portuguese individuals, 57 with hereditary spherocytosis (HS) and 25 unaffected controls. We performed standardized diagnosis tests, including electrophoretic membrane protein analysis to identify and quantify protein deficiencies underlying HS. Membrane bound hemoglobin (MBH) and band 3 profiles were determined as oxidative stress and aging markers.

Analysis of the human saliva proteome.

Interest in the characterization of the salivary proteome has increased in the last few years. This review discusses the different techniques and methodologies applied to the separation and identification of salivary proteins. Nowadays, proteomic techniques are the state of the art for the analysis of biologic materials and saliva is no exception.
