Compositions and methods are disclosed for use in the analysis and quantitation of conjugated and unconjugated bilirubin in patient or other samples. The compositions have the general formula:
1
wherein:
R
1
and R
2
are independently selected from alkyl and aryl,
R
3
and R
4
are independently selected from hydrogen, alkyl, alkenyl, tauryl, aryl, and glucoronyl, and
R
5
, R
6
, R
7
, R
8
, R
9
and R
10
are each independently selected from hydrogen and alkyl, and are resistant to oxidation, as occurs in bilirubin upon exposure to light and air. These properties make them ideal for use in calibration and control solutions for use in medical and research bilirubin analysis, or other applications where stable reagents for bilirubin analysis is desirable.
本发明公开了用于分析和定量患者或其他样本中结合胆红素和非结合胆红素的组合物和方法。这些组合物的通式如下
