Advantages of Sirius Red staining for quantitative morphometric collagen measurements in lungs.

abstract：BACKGROUND AND PURPOSE:Serum amyloid A (SAA), an acute-phase protein whose level tracks infection and inflammation, is the precursor protein of amyloid A (AA) fibrils that is thought to cause AA amyloidosis in human and animals. SAA protein has several isoforms based on the difference of amino acid sequence, such as SA...
