PRINCIPLE (The method is based on the specific binding of bromocresol green (BCG), an anionic dye, and the protein at acid pH 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. α2-Macroglobulin contributed a 58 – 92% increase in ALBBCG values. Community Bureau of Reference of the Commission of the European Communities. This product could help you, Accessing resources off campus can be a challenge. 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. Store it in the dark. Bromocresol Purple TS —Dissolve 250 mg of bromocresol purple in 20 mL of 0.05 N sodium hydroxide, and dilute with water to 250 mL.

Bromocresol green is green at pH levels between 3.8 and 5.4. In some patients with nephrotic syndrome, the monomeric haptoglobin was detected in the urine, and urine/serum haptoglobin ratio was high.28 Proteomic analysis using two-dimensional gel electrophoresis also indicated that haptoglobin is one of the urinary proteins characteristic of massive proteinuria in patients.29 These findings suggest that a significant amount of haptoglobin leaks into the urine in such patients. Software Solutions. The indicator is made from bromocresol green powder dissolved in ethanol. In nephrotic syndrome, ΔALB, calculated by subtracting nALB from ALBBCG, was significantly correlated with the concentration of α2-macroglobulin, but not with that of haptoglobin (Figures 3(a) and (b)). This might explain why the serum haptoglobin concentration was not higher in the NS-1 group compared with the NS-2 group in this study (Table 2). Bromocresol green CAS 76-60-8 indicator ACS,Reag. Test Solution) B-297 | 62625-32-5 | Spectrum Chemical.

The molecular weight of the largest phenotype (Hp2-2) exceeds 400 kDa, which is more than half that of α2-macroglobulin. Some researchers proposed to set different reference intervals for serum albumin concentration in the BCG and BCP assays.30 In fact, ALBBCG was highly correlated with nALB in the present study (Figure 1). The color intensity of the complex is photometrically measured and is proportional to the concentration of albumin.
