In clinical settings, human serum albumin (HSA) is widely quantitated on the basis of change in the color of bromocresol purple (BCP) bound to HSA. However, the binding sites of BCP on HSA are hitherto unknown. We have identified these

Polyvinyl chloride (PVC) dyed with bromocresol purple was investigated as a high-dose radiation dosimeter. The absorbance at 417 nm depends linearly on the dose below 50 kGy. The response depends neither on dose rate nor on the irradiation temperature. The

Hypoalbuminemia is known to occur in critically ill patients and is associated with increased mortality. Severe hypoalbuminemia is defined in the literature as serum albumin levels lower than 24 g/L. Albumin levels were measured in our laboratory using the bromocresol

Determination of thermodynamic parameters of water oxidation at the photosystem II (PSII) manganese complex is a major challenge. Photothermal beam deflection (PBD) spectroscopy determines enthalpy changes (ΔH) and apparent volume changes which are coupled with electron transfer in the S-state
