Total protein detection method |
| abstract |
Disclosed is an improved assay for the determination of total protein in an aqueous test fluid such as urine. The assay involves combining the test fluid with a molybdate or tungstate salt and a dye which forms a complex with molybdate or tungstate ion at a pH of 1.0 to 3.0 to shift the absorption band of the complex in the presence of protein. There is introduced into the assay a substituted phenolsulfonephthalein dye having a pKa which enables it to operate at a pH of from about 1.0 to 3.0 and whose affinity for protein is such that it will provide a detectable response only in the presence of greater than 50 mg/dL of protein to increase the scope of the assay. |
