Although the original BCP assay underestimates the albumin concentration in uremic patients due to increased carbamylated albumin,33 ALBmBCP agreed well with nALB, suggesting that the mBCP assay converted the reduced form of albumin into the oxidized form successfully. 58 / Monday, March 26, 2012 / Rules and Regulations Date of issue: 08/13/2014 Revision date: 12/19/2016 Supersedes: 08/13/2014 Version: 1.1 12/19/2016 EN (English US) Page 1 SECTION 1: Identification . The aim of this paper was to examine the differences in albumin measurements between the Advia2400 BCG method (AlbBCG), Dimension RxL BCP (AlbBCP) and capillary zone electrophoresis (CZE). Background: Usually serum albumin is measured with dye-binding assay as bromocresol green (BCG) and bromocresol purple (BCP) methods.

Representative electrophoretic patterns of serum protein fractions separated on cellulose acetate membrane. With a few exceptions, such as multiple myeloma34 or penicillin G-treated patients,35 mBCP assay can be used to measure the serum albumin concentration precisely with sufficient accuracy. Mix 9 mL of the resulting solution with 1 mL of dilute glacial acetic acid (1 in 300). In our previous experiments, we added purified haptoglobin to albumin solutions and measured ALBBCG and ALBmBCP.23 Although albumin concentrations were exactly the same in all solutions, ALBBCG, but not ALBmBCP, was increased in a dose-dependent manner.23 In inflammation, hepatic synthesis of haptoglobin is induced by inflammatory cytokines.24 By contrast, the serum α2-macroglobulin concentration does not increase in inflammation in humans.25,26 In nephrotic syndrome, the haptoglobin concentration reached a plateau in the NS-2 group, and NS-1 and NS-2 groups showed similar haptoglobin concentrations (Table 2). window.figureViewer={doi:'10.1177/0004563215574350',path:'/na101/home/literatum/publisher/sage/journals/content/acbb/2016/acbb_53_1/0004563215574350/20170109',figures:[{i:'table1-0004563215574350',type:'table-wrap',g:[{m:'10.1177_0004563215574350-table1.gif',l:'10.1177_0004563215574350-table1.jpeg',size:'514 KB'}]} We measured serum albumin concentrations in 33 patients with NS and 13 reference healthy controls using BCG (ALBBCG) and mBCP (ALBmBCP) assays, and nephelometry (nALB) as a reference method. All of the immunoglobulins were decreased markedly in nephrotic syndrome. Colloid osmotic pressure correlated less strongly with total protein and with albumin by bromocresol purple than with albumin by the two bromocresol green methods. This study clearly indicates that α2-macroglobulin causes a positive bias for ALBBCG in nephrotic syndrome, especially in patients with severe hypoalbuminemia. All of the subjects agreed to participate in this study and provided written informed consent after being made fully aware of the study protocol. Title; Safety Data Sheet (SDS) Bromocresol green Certificates of Analysis. Among the five proteins classified into α1- and α2-globulins, the mean values of α1-microglobulin, α2-macroglobulin and haptoglobin were markedly increased in nephrotic syndrome (Table 2).

CHEMetrics' total alkalinity tests determine total or M alkalinity using a hydrochloric acid titrant and a bromocresol green/methyl red indicator. Such clinical features constitute nephrotic syndrome.8 The measurement of the serum albumin concentration is of great importance in the diagnosis and management of patients with nephrotic syndrome.9, In clinical practice, the serum albumin concentration is usually measured by dye-binding methods, such as the bromocresol green (BCG) assay or bromocresol purple (BCP) assay.10 The BCG assay reacts non-specifically with α-globulins (especially α2-globulin), concentrations of which are increased in inflammation.11,12 Although the BCP assay is more specific for albumin than is the BCG assay, the reactivity to albumin is different between the oxidized and reduced forms.2 However, the modified BCP (mBCP, an improved formula of the original BCP) assay reacts with reduced and oxidized albumin equally.2 Although earlier studies indicated that the BCG assay has the greatest reactivity with α2-globulin,13,14 α2-globulin is a collective term for various proteins with α2-mobility on electrophoresis, and it is likely that the composition of α2-globulin changes depending on clinical conditions.

Traditionally, serum albumin is a biomarker used to identify malnutrition in patients.1,2 Also, it is well established that albumin levels fall in patients with inflammatory disorders and other acute or chronic diseases by suppressing synthesis, increasing catabolism and/or vascular permeability, or a combination of these processes.1 Low serum albumin levels have been associated with higher mortality in a number of different populations, in pathways that may not result solely from malnutrition.

In vitro, when α2-macroglobulin was added to solutions containing identical albumin concentrations, α2-macroglobulin dose-dependently increased ALBBCG, but not ALBmBCP. The correlations of ΔALB with α2-macroglobulin (a) and haptoglobin (b) were examined. Order Status Contact Us Login.

Here, we warn that the BCG assay should never be used in nephrotic syndrome because it shows high reactivity with α2-macroglobulin, which is increased in these patients. Points to remember.

This difference rose to nearly 30% in the NS-1 group (Table 2). Human α2-macroglobulin is a multifunctional glycoprotein that forms a homotetramer of ∼725 kDa.22 α2-Macroglobulin binds non-specifically to various proteinases, which cleave the susceptible site (thioester) of α2-macroglobulin.
