Human serum amyloid A (SAA)
Serum amyloid A apol ipoprote in family consists of three members that in human beings are coded by different genes: SAA1, SAA2, and SAA4 (reviewed in 1-3). SAA1 and SAA2 are so-called acute phase isoforms. Their expression is increased in response to inflammation. SAA4 is a constitutive isoform, the expression of which does not change during an acute-phase response. In addition, one more relat...
متن کاملHeparan sulfate dissociates serum amyloid A (SAA) from acute-phase high-density lipoprotein, promoting SAA aggregation.
Inflammation-related (AA) amyloidosis is a severe clinical disorder characterized by the systemic deposition of the acute-phase reactant serum amyloid A (SAA). SAA is normally associated with the high-density lipoprotein (HDL) fraction in plasma, but under yet unclear circumstances, the apolipoprotein is converted into amyloid fibrils. AA amyloid and heparan sulfate (HS) display an intimate rel...
متن کاملEvaluation of an in-clinic Serum Amyloid A (SAA) assay and assessment of the effects of storage on SAA samples
BACKGROUND An in-clinic assay for equine serum amyloid A (SAA) analysis, Equinostic EVA1, was evaluated for use in a clinical setting. Stability of SAA in serum samples was determined. METHODS Intra- and inter- assay variation of the in-clinic method was determined. The in-clinic method (EVA1) results were compared to a reference method (Eiken LZ SAA) with 62 patient samples. For samples with...
متن کاملEvaluation of a commercially available human serum amyloid A (SAA) turbidometric immunoassay for determination of equine SAA concentrations.
The aim of the present study was to evaluate whether equine serum amyloid A (SAA) concentrations could be measured reliably with a turbidometric immunoassay (TIA) developed for use with human serum. Intra- and inter-assay imprecision were evaluated by multiple measurements on equine serum pools. Assay inaccuracy was determined by linearity under dilution. The assay was subsequently used for mea...
متن کاملSome properties of antisera to serum amyloid A protein (SAA): inhibition of precipitation by complexing of SAA to albumin
Three potent rabbit antisera to human serum amyloid A protein (SAA) appear to be directed exclusibely to the carboxy terminal region not shared with the tissue amyloid A protein. Since binding to albumin completely blocks the reaction of these antisera with the antigen, and since SAA exists in serum complexed to albumin, the anti-SAA cannot be used to detect or quantitate this serum component. ...
