Fluorescent and colored compounds used in molecular biology labs may generate color quench in wipe test samples taken from such labs. The ability of conventional chemical quench curves to correct for color quench caused by fluorescent and colored compounds in

Tetracycline antibiotics (TCs) such as doxycycline (DOTC), chlortetracycline (CTC), oxytetracycline (OTC), and tetracycline (TC) react with Cu(II) in pH 3.5 BR buffer medium to form 1:1 cationic chelates, which further react with titan yellow to form 2:1 ion association complexes.
In photometry, where both the product formed and one or several reactants absorb light at the same wavelength, the absorbance of the "blank" of the sample at the end of the reaction may be less than that measured at the
The Magneson and Titan yellow tests were used to detect Mg in amyloid deposits in primary and secondary amyloidosis, in a pituitary tumour and in a case of equine cutaneous amyloidosis. Especially vascular amyloid deposits turned out to contain high

A resonance light scattering method for the determination of trace proteins was developed. In the presence of Triton X-100, proteins reacted with Titan yellow to form a combination product, resulting a significant enhancement of resonance light scattering (RLS). The deltaI(RLS)
