objective: estrogen receptor alpha protein status is determined by routine immunohistochemistry analysis in all malignant breast tumors. this assay has its limitations. rna based techniques are potential complements for immunohistochemistry but it must be noticed that gene silencing may occur at different levels from rna to protein. the aim of this study was the comparison of the results from t...

Objective: The aim of this experiment was to determine chemical composition, protein quality of corn gluten meal (CGM) and its effect on growth performance of broiler chicks. Methods: Chemical composition and nitrogen corrected true metabolizable energy of CGM was determined by standard and precision-fed cockerel assay methods.  For evaluating of protein quality, 90 male broiler chicks in a com...

Protein A immobilized on various chromatography media is commonly used to purify antibodies. Even when covalently attached, Protein A can leach off of the chromatography support and co-elute with the antibody. For applications such as the therapeutic use of the antibody, contamination with Protein A must be minimized to avoid any adverse patient effects. This immunoassay method provides sensiti...

There has been an increase in the number of colorimetric assay techniques for the determination of protein concentration over the past 20 years. This has resulted in a perceived increase in sensitivity and accuracy with the advent of new techniques. The present review considers these advances with emphasis on the potential use of such technologies in the assay of biopharmaceuticals. The techniq...
